WEBVTT 00:00.280 --> 00:00.640 Well. 00:00.640 --> 00:05.440 Hello Mac people and Linux people, welcome to your setup video series. 00:05.440 --> 00:07.720 If you're a PC user, then what are you doing here? 00:07.720 --> 00:09.000 We just set up your environment. 00:09.000 --> 00:09.680 You're set. 00:09.720 --> 00:11.160 Go on to the next lecture. 00:11.480 --> 00:14.280 All right, Mac people, I had a rough time with the PC lot. 00:14.320 --> 00:16.760 I am this is this is my sweet spot. 00:16.800 --> 00:21.720 I'm a I'm a mac user, so this hopefully is going to be very easy and fun. 00:22.040 --> 00:22.640 All right. 00:22.640 --> 00:24.800 So I'm in a finder window here. 00:24.800 --> 00:29.880 And I've gone into utilities applications utilities to show you that that's where you can find terminal 00:29.920 --> 00:32.800 to open up a terminal if you're not familiar with that. 00:32.800 --> 00:36.760 But I'm going to now assume that you know about this and open up a terminal. 00:36.840 --> 00:39.640 Here's one right here and make that a bit bigger for you. 00:39.760 --> 00:40.480 Hang on. 00:40.600 --> 00:45.960 So this this is where we are going to do some of the next few steps. 00:46.240 --> 00:50.080 And we've actually got a five step process for setting up your environment. 00:50.080 --> 00:56.600 And this is the first step which is about cloning the repo or getting a copy of the code for the class 00:56.600 --> 00:58.000 onto your local box. 00:58.160 --> 01:01.610 Now I'm in my home directory here if I do PWD. 01:01.650 --> 01:06.330 If you're not familiar with the command prompt, I've included a guide to get you more comfortable more 01:06.330 --> 01:08.490 confident using the command line. 01:08.850 --> 01:13.730 It's common for people to have a directory called projects in their home directory where they put all 01:13.730 --> 01:15.690 of their their work projects. 01:15.690 --> 01:19.210 And if you have that, then if you do CD projects, it will go in there. 01:19.250 --> 01:25.930 Now it looks like I don't have one, so I have to make one with make directory projects and then change 01:25.930 --> 01:26.970 to projects. 01:26.970 --> 01:31.850 And now I'm in my empty projects directory, but you may have a few projects in there. 01:32.050 --> 01:36.530 So the next step is now to bring the GitHub repo here. 01:37.130 --> 01:45.450 And so what we now do is we go using our favorite browser to a, a page where we have the repo which 01:45.450 --> 01:47.210 is linked in the course materials. 01:47.210 --> 01:52.650 This is what the repo looks like when you go to GitHub to my name and you see the repo here, here are 01:52.650 --> 01:57.570 all of the directories, one for each of the weeks that we have coming up ahead of us, and then some 01:57.570 --> 01:58.130 general stuff. 01:58.130 --> 02:01.940 And if you scroll down you see something that's known as the project Readme. 02:01.940 --> 02:04.340 And it's really important because it's got great stuff in there. 02:04.340 --> 02:07.580 And I urge you to read the readme and the things it links to. 02:07.620 --> 02:11.900 It begins with some stuff which includes another appeal to LinkedIn with me. 02:11.940 --> 02:14.100 I seem to be quite desperate on this front. 02:14.300 --> 02:17.380 And then comes the setup instructions. 02:17.380 --> 02:18.700 And there's a link for windows. 02:18.700 --> 02:20.300 Instructions for the other guys. 02:20.300 --> 02:22.540 There's a link for Mac and Linux. 02:22.780 --> 02:25.860 Come follow that link to get step by step instructions. 02:25.860 --> 02:30.300 And to be honest, those instructions are going to be way clearer than than this video. 02:30.300 --> 02:32.740 And I'm going to keep them updated when people have problems. 02:32.740 --> 02:35.500 So that should really be your first place to go. 02:35.540 --> 02:38.260 And this video see it as like a video that goes along through it. 02:38.260 --> 02:40.060 So you get get a sense for it. 02:40.500 --> 02:45.820 But the Readme also has lots of useful resources and a ton of important stuff on API costs that I urge 02:45.820 --> 02:47.820 you to read, because I know this is a sensitive topic. 02:47.860 --> 02:54.100 And so please do look through it and read all the other stuff and the links to the guides and so on. 02:54.940 --> 02:58.780 And I should probably mention that if you've not used GitHub before, you might need to create a new 02:58.870 --> 03:01.230 account with GitHub to get to this point. 03:01.670 --> 03:07.590 Now, just before we clone this repo locally, I'd like to go back to the terminal window and I just 03:07.590 --> 03:14.350 want you to type git minus minus version to check that you've got git installed on your Mac, and it 03:14.350 --> 03:17.470 should come up like mine does with a version number. 03:17.750 --> 03:20.430 If it doesn't, you might need to run this command. 03:20.470 --> 03:27.630 Xcode select minus minus install, which installs some of the basic developer tools on your Mac. 03:27.670 --> 03:30.150 I've got a link to that in the setup instructions. 03:30.150 --> 03:34.710 I won't do it since I already have Xcode and Developer tools installed. 03:34.750 --> 03:39.590 Okay, so with that, if you're typing git minus minus version, you're getting a number there. 03:39.590 --> 03:46.310 You come to the repo, you've signed in to GitHub, there's this green code button on the top right. 03:46.510 --> 03:47.990 And you press there. 03:48.110 --> 03:52.950 And probably I recommend that at this point you select the Https version. 03:53.070 --> 03:56.470 I'm going to pick this version because I have that kind of credential. 03:56.470 --> 03:58.470 But but you can also pick the other one. 03:58.560 --> 04:04.040 and then you copy that into your clipboard by pressing the copy button right there. 04:04.400 --> 04:10.520 So once you've copied this text, which is the link to this, this repo, you then come back to the 04:10.520 --> 04:11.240 command line. 04:11.240 --> 04:16.360 And in your projects directory there I am I'm inside users ed projects. 04:16.360 --> 04:23.720 I'm now going to type git clone, and then the repo link that I've pasted from my clipboard. 04:23.920 --> 04:27.640 And I press enter and in it comes and it's done. 04:27.840 --> 04:31.640 If I now have a look you'll see that there is a directory called agents. 04:31.760 --> 04:38.400 If I go into agents I now see that I have directories for the full project. 04:38.840 --> 04:44.280 And I want to mention that where we are right now in this directory that's in my projects directory, 04:44.280 --> 04:45.840 the agents directory. 04:46.000 --> 04:50.120 This here, this is known as the project root directory. 04:50.120 --> 04:54.720 If you're inside the sort of top level directory of your project of agents. 04:54.880 --> 04:56.200 So this is the project root. 04:56.200 --> 04:58.970 And you'll hear that referred to during the course and generally. 04:58.970 --> 05:00.810 And so it's worth knowing that that's what it is. 05:00.810 --> 05:04.250 But that is step one of the setup complete. 05:04.890 --> 05:05.290 Okay. 05:05.290 --> 05:07.530 Welcome to step two of the setup for Mac. 05:07.530 --> 05:13.050 We're going to now install cursor the I IDE which is great. 05:13.050 --> 05:13.930 It is fabulous. 05:13.930 --> 05:14.850 And you're going to love it. 05:14.890 --> 05:17.410 If you've already got cursor then of course you can skip this step. 05:17.650 --> 05:20.650 Otherwise bring up your favorite browser and go to cursor. 05:22.090 --> 05:25.250 And here we have the screen for installing cursor. 05:25.290 --> 05:29.610 You will need to begin by creating an account using the sign up button over here. 05:29.610 --> 05:32.250 If you don't have one already and it will just guide you through. 05:32.250 --> 05:40.330 I use my Google credentials myself, and I selected a Trial Pro plan myself, which is a free at least 05:40.330 --> 05:40.770 for now. 05:41.050 --> 05:46.130 And I then press download for Mac, which then brings down an installer. 05:46.130 --> 05:50.890 I then run that installer and it then asks me a couple of questions. 05:50.890 --> 05:53.810 I log in and then it installs it. 05:53.850 --> 05:56.490 I mean, I'm sure you are used to these things. 05:56.490 --> 06:01.900 You then drag and drop into applications and you open that up and it will install it. 06:01.940 --> 06:02.980 Easy peasy. 06:03.420 --> 06:07.540 I selected all of the default setup instructions, nothing special at all. 06:07.540 --> 06:10.540 And then you should launch it and you should be in cursor. 06:10.540 --> 06:12.740 And that is where we will go next. 06:13.620 --> 06:13.940 Okay. 06:13.980 --> 06:19.180 So once you've opened up cursor freshly installed this is what it should look like a nice big empty 06:19.220 --> 06:19.780 screen. 06:19.780 --> 06:23.500 And we're going to press the open project button right here. 06:23.780 --> 06:30.220 And we're going to then navigate to projects wherever that is. 06:30.220 --> 06:36.660 I guess it's going to be at the top projects and then agents, which is the new folder that we've just 06:36.660 --> 06:37.100 installed. 06:37.100 --> 06:39.780 This is known as the project root folder. 06:39.780 --> 06:40.660 Here it is. 06:40.860 --> 06:43.100 And then we're going to press open. 06:43.420 --> 06:45.060 And here it is. 06:45.900 --> 06:47.180 Cursor opens up. 06:47.180 --> 06:53.340 We've got a nice screen here that's known as the explorer which shows all of the files organized by 06:53.340 --> 06:54.180 directories. 06:54.180 --> 06:55.580 One of these directories might be open. 06:55.580 --> 06:59.190 You can just click the switch to collapse it like that. 06:59.230 --> 07:02.950 There might be a box up here with some sort of welcome to cursor, blah blah blah. 07:02.990 --> 07:06.750 Just X out of that extra box on the top left if it's there for you. 07:07.110 --> 07:11.710 Over here is a chat screen where you can chat with an AI about your code. 07:11.750 --> 07:15.350 And I'm going to suggest for now we x out of that as well to keep things really clean. 07:15.390 --> 07:18.430 So what we're looking at now is a nice big area here. 07:18.670 --> 07:25.870 And the code the explorer to look at our directories right here, including the Readme and so on. 07:25.910 --> 07:29.190 And congratulations you are into cursor. 07:29.390 --> 07:33.070 And that is the second step of the instructions completed. 07:33.790 --> 07:37.990 And we are now onto step three of the instructions which are my very favorite step where you're going 07:37.990 --> 07:38.630 to install. 07:38.670 --> 07:45.390 You've the package manager which is so fabulous, so quick and easy to use, and you're going to be 07:45.390 --> 07:46.870 really happy about this. 07:46.870 --> 07:52.150 I know it's like another new thing to learn, which is always a pain, but I tell you, it's so great. 07:52.190 --> 07:58.280 The reason we're doing this is partly because a student on my prior course, said, you know, you really 07:58.280 --> 07:59.240 should use UV. 07:59.280 --> 08:00.560 It's so much better. 08:00.560 --> 08:02.120 And so I'd heard of it. 08:02.120 --> 08:07.000 I knew it was doing the rounds, but I hadn't actually used it myself until that, and that pushed me 08:07.000 --> 08:07.520 to do it. 08:07.520 --> 08:09.160 And I've never looked back. 08:09.200 --> 08:15.000 And we'll find that many of the AI platforms, the agent platforms will use or use UV themselves. 08:15.000 --> 08:16.920 So it's going to work out really well for us. 08:16.920 --> 08:20.640 You're going to be grateful I showed you this if you're not already a UV convert. 08:20.640 --> 08:21.280 All right. 08:21.520 --> 08:24.360 So first step is to install UV. 08:24.520 --> 08:28.080 And the way you do that is you bring up a browser window. 08:28.240 --> 08:32.880 And yeah you can just Google for UV package manager. 08:32.880 --> 08:39.000 Or you can look at the link that I'll have in the instructions, and you'll see that there is the um 08:39.400 --> 08:40.560 link to the GitHub. 08:40.600 --> 08:44.720 And it has within it some clear installation instructions. 08:44.720 --> 08:50.920 You just simply have to run this one command in a terminal, and I will copy that to the clipboard. 08:50.920 --> 08:51.680 There it is. 08:52.000 --> 08:56.770 Now there's actually a new easy way to run things in a terminal because you can do it within cursor. 08:56.810 --> 08:59.210 Here's my cursor screen again. 08:59.210 --> 09:01.610 And there's actually a view menu. 09:01.610 --> 09:03.770 And you can go view and then terminal. 09:03.770 --> 09:09.170 Or you can know to press the control button not the command button, not the one with the squiggle clover 09:09.170 --> 09:13.210 on it, but the control button on the bottom left of your keyboard control. 09:13.210 --> 09:16.330 And then the tick mark on the top left of your keyboard. 09:16.370 --> 09:17.570 Or at least on my keyboard. 09:17.610 --> 09:18.770 And up comes a terminal. 09:18.770 --> 09:21.370 But you could also go to the view menu and choose terminal. 09:21.370 --> 09:22.330 And here it is. 09:22.370 --> 09:27.250 And now you can simply paste in that command to run the installation for you've. 09:27.250 --> 09:29.170 And it will be super quick and you'll be done. 09:29.170 --> 09:30.970 I'm not going to run it because I've already run it. 09:31.330 --> 09:36.370 Once you've done that, you might need to close this terminal by pressing the the X, and you might 09:36.370 --> 09:41.850 actually need to to quit out of right right out of cursor and bring back up cursor because it needs 09:41.850 --> 09:43.770 to refresh its environment variables. 09:43.770 --> 09:48.850 But but if you've done that then if you type UV minus minus version, it should give you a version number 09:48.850 --> 09:52.690 which is telling you that all is good, UV is installed. 09:53.090 --> 09:57.100 And uh, with that we are almost ready to go. 09:57.140 --> 09:59.380 There is now only one command left. 10:00.060 --> 10:01.380 And what is that command? 10:01.420 --> 10:02.100 I hear you ask. 10:02.100 --> 10:04.180 It is simply to type at this point. 10:04.220 --> 10:07.060 You see like that. 10:07.100 --> 10:12.540 And what that's going to do is it's going to look at some of the other files here, like a Python version 10:12.540 --> 10:17.820 file and a pyproject.toml and some other things and a UV lock. 10:17.860 --> 10:22.220 And it's going to use that to build our environment and let's see it doing that. 10:22.220 --> 10:23.100 Off it goes. 10:23.460 --> 10:28.020 Now I told you that it's quick and you'll see that it was very quick. 10:28.180 --> 10:29.660 That is just done. 10:29.660 --> 10:32.020 But that's actually quicker than it will be for you. 10:32.060 --> 10:34.900 And it's that quick because it does cache things that I've done before. 10:35.140 --> 10:39.340 When you do this, it's going to take about three minutes, four minutes, which is still very quick 10:39.340 --> 10:42.780 because Anaconda takes like an hour or something. 10:42.900 --> 10:47.660 So it's going to be fast, but there is still a lot to be installed, so you'll have to sit back and 10:47.660 --> 10:54.980 wait while everything installs, but enjoy the raw power of UV as everything gets built there And once 10:54.980 --> 10:57.660 it's done, what you may notice is that there's a new. 10:57.700 --> 11:03.620 Directory called dot that's appeared, which is like a traditional Python virtual environment. 11:03.620 --> 11:07.220 If you know these things that it's created one for this project. 11:07.220 --> 11:11.660 And so one of the really nice things about UV is that it's compatible and consistent with all of the 11:11.660 --> 11:13.500 other ways you do things in Python. 11:13.500 --> 11:16.460 It's not like there's a new sort of thing like Conda. 11:16.660 --> 11:23.140 So it's that's been set up and now that is going to be the environment that we'll be using from this 11:23.140 --> 11:24.140 point onwards. 11:24.300 --> 11:30.260 And when you run a Python script, whereas before you might have typed Python and then something, what 11:30.260 --> 11:36.580 you're going to type now is you've run and then that same thing and that automatically makes sure that 11:36.580 --> 11:38.780 it runs in that environment. 11:39.180 --> 11:44.620 The other thing to mention is that it has installed a dedicated version of Python, right? 11:44.620 --> 11:45.700 For this project. 11:45.700 --> 11:48.340 It is in fact a Python version 3.1. 11:48.860 --> 11:51.940 Uh, whilst the latest version of Python is 3.13. 11:51.980 --> 11:53.180 That's not yet not. 11:53.180 --> 11:55.550 Not all data science packages are ready for that yet. 11:55.550 --> 11:59.790 So 3.1 is what we're using and everything will be in that Python. 11:59.790 --> 12:03.630 It will have installed it for you if you didn't already have it, and it will be dedicated for this 12:03.630 --> 12:04.230 project. 12:04.270 --> 12:05.590 UV is really good. 12:05.590 --> 12:13.630 It combines this kind of isolated environment with something that is fast and simple, and I very much 12:13.630 --> 12:16.190 hope that this will have simply worked for you. 12:16.190 --> 12:20.110 And that means that step three is done and we can move on to step four. 12:20.710 --> 12:24.670 So for step four, we're going to set up a key with OpenAI. 12:25.190 --> 12:31.670 Now again I want to emphasize that whilst I do encourage you to be setting up a key with OpenAI and 12:31.670 --> 12:35.870 to be using that API, it is not required for this project for this course. 12:35.870 --> 12:39.310 And there are alternatives in the Readme, but that's what we're going to do now. 12:39.350 --> 12:42.070 I'm going to assume that you are good for this and that we can come in. 12:42.070 --> 12:48.150 And so you go to platform dot Openai.com just here like that. 12:48.310 --> 12:55.160 And this brings you to the front screen of OpenAI where you get to set up an account. 12:55.160 --> 12:59.280 If you don't have one already, sign up or log in if you have one. 12:59.280 --> 13:01.880 And I'm going to log in because I already have one. 13:02.000 --> 13:04.480 Log in with my Google credentials. 13:04.480 --> 13:06.920 And here we have my account. 13:06.920 --> 13:09.840 We're logged in and you will hopefully have done the same. 13:09.880 --> 13:11.400 Let me make this nice and big for you. 13:12.320 --> 13:13.040 Okay. 13:13.200 --> 13:17.240 So there are now two things that we have to do now that we're in OpenAI. 13:17.240 --> 13:22.360 And we're going to go and do both of them now bearing in mind this is not required, you can also do 13:22.360 --> 13:27.720 the same thing, this analogous website for deep seek and for many others, you could be setting up 13:27.720 --> 13:31.720 your keys in any of them and just follow the same kind of process. 13:31.720 --> 13:33.040 But let's get to that now. 13:33.600 --> 13:35.000 So as I say, it's two steps. 13:35.000 --> 13:40.000 The first of them is to go to the settings menu up here and come down to billing. 13:40.000 --> 13:43.440 And this is where you set up your billing details. 13:43.600 --> 13:48.600 Now you have to apply a credit balance giving OpenAI some money in advance. 13:48.600 --> 13:52.930 And I've given it quite a lot of money right here because I'm doing various different things and you 13:52.930 --> 13:55.690 do not need to give it that much money by any means. 13:55.970 --> 13:57.690 There is a minimum top up. 13:57.690 --> 14:02.330 They require at least $5 as of right now, but they are. 14:02.690 --> 14:04.370 They sometimes have deals. 14:04.410 --> 14:06.490 There's something going on down here that you could read about. 14:06.490 --> 14:11.850 Perhaps there's some some deal for free tokens right now, but there's different deals and you can press 14:11.850 --> 14:15.610 the Add to credit balance to put in your $5 up front. 14:15.650 --> 14:18.130 That's that's, I believe, required right now. 14:18.370 --> 14:22.890 And we'll only spend a few dollars of that on this course, and that you have complete flexibility and 14:22.890 --> 14:28.050 you can come back and watch to what extent you're spending your credits as we go through. 14:28.210 --> 14:30.850 But but I suggest doing that, putting in your $5. 14:30.850 --> 14:33.850 But bear in mind, if you don't want to, you don't need to. 14:34.090 --> 14:37.650 Once you've done that, you then turn to the API keys. 14:37.690 --> 14:44.250 Part of this, which is where you get to see the key that you've set up that you will use for this project. 14:44.530 --> 14:49.210 And if you already have a key, then then great, you're in good shape, but I assume you don't, in 14:49.210 --> 14:50.770 which case you press this green. 14:50.770 --> 14:53.100 Create new secret key. 14:53.460 --> 14:56.420 You leave, you give it a name that just doesn't matter. 14:56.420 --> 14:57.900 Just for your future reference. 14:57.900 --> 15:03.980 And then for projects, be sure to choose default Project and leave it as all permissions and then press 15:03.980 --> 15:05.940 Create Secret Key. 15:06.300 --> 15:07.540 It's then going to prompt you. 15:07.540 --> 15:09.980 It's going to bring up your key that you'll use. 15:09.980 --> 15:11.940 And you can copy it into your clipboard. 15:11.980 --> 15:16.340 And we're going to paste it in a moment into cursor in a place where we were going to use it. 15:16.740 --> 15:17.900 Now here's the thing. 15:17.900 --> 15:20.900 Here is a nasty gotcha to be aware of. 15:21.180 --> 15:27.500 It's very tempting to take your key and paste it into a useful app, like, like the notepad or something, 15:27.780 --> 15:30.260 but there's a trap there you need to be careful of. 15:30.460 --> 15:33.140 Some programs, I think, including notepad. 15:33.300 --> 15:39.660 If you paste in some text and then press enter, it changes some of the characters in that text to be 15:39.660 --> 15:45.340 nicer, formatted like it turns hyphens into long hyphens, and that can be really hard to spot. 15:45.340 --> 15:48.140 And that will then basically invalidate your key. 15:48.180 --> 15:52.630 Your key will now be a different set of letters or characters, and when you try and use that in your 15:52.630 --> 15:56.550 file, it's going to fail and it's going to be almost impossible to track it down because it's going 15:56.590 --> 15:57.430 to look perfect. 15:57.430 --> 15:58.790 And it's really frustrating. 15:58.790 --> 16:00.910 And a lot of people have had that problem. 16:00.910 --> 16:06.670 So I urge you just to copy it into the clipboard and paste it straight into cursor in the next step. 16:06.790 --> 16:09.070 And it is good to to keep a copy of it somewhere. 16:09.070 --> 16:14.310 Just be really careful to make sure you do it in a way that doesn't overwrite your characters, so that 16:14.310 --> 16:18.270 you're keeping the original and and it feels in good shape. 16:18.270 --> 16:23.390 So there is my, uh, public service announcement about about things to watch out for with keys. 16:23.390 --> 16:29.070 But hopefully you've set up your key, you've copied it to the clipboard, you've maybe made a backup 16:29.070 --> 16:30.350 somewhere safe. 16:30.550 --> 16:32.630 And now we're ready for the next part. 16:33.270 --> 16:36.230 And this is step five of the environment set up. 16:36.230 --> 16:37.030 And it's the last step. 16:37.030 --> 16:38.470 We're almost completely done. 16:38.470 --> 16:41.270 We're back in cursor again looking at cursor. 16:41.430 --> 16:45.270 And I'm just going to I'm going to press an X here to get rid of that screen. 16:45.270 --> 16:47.550 I'm going to press an X to get rid of my terminal. 16:47.550 --> 16:50.510 So we're looking at a nice clean page here. 16:50.920 --> 16:51.320 now. 16:51.360 --> 16:53.280 Down here in the explorer. 16:53.320 --> 16:55.160 I've collapsed all these folders. 16:55.160 --> 16:59.840 I'm going to right click and say new file at the bottom here. 16:59.840 --> 17:01.520 And I'm going to create a new file. 17:01.520 --> 17:03.720 And I'm going to give it a very precise name. 17:03.720 --> 17:06.200 And you have to give it exactly the same name. 17:06.200 --> 17:09.960 If you get this wrong by a single character, then you're going to have problems later. 17:10.000 --> 17:11.880 So so be careful with this one. 17:11.880 --> 17:19.200 It starts with a dot, the period, a full stop, and then the letters E, dot, E, env. 17:19.200 --> 17:21.520 And it's got to be called exactly that. 17:21.760 --> 17:23.120 And you'll see why later. 17:23.120 --> 17:30.080 But basically this this is a file which is often used to store environment variables, things that will 17:30.080 --> 17:36.080 load into our environment as variables that we'll use for things like passwords and tokens and keys. 17:36.240 --> 17:38.760 And it doesn't get checked into GitHub. 17:38.760 --> 17:42.400 So it stays as a private file just for you. 17:42.400 --> 17:45.080 And it's a common technique for managing these kinds of things. 17:45.120 --> 17:46.520 And it's called dot env. 17:46.520 --> 17:47.960 And it has to be called exactly that. 17:48.320 --> 17:53.730 So what we can now do is type into here a key that we want to to remember. 17:53.730 --> 17:57.530 And in particular the one that we want to remember is OpenAI's key. 17:57.650 --> 18:01.650 And it's it's OpenAI underscore API underscore key. 18:01.650 --> 18:05.490 And it's actually prompting me right here for it because cursor is that clever and knows what we're 18:05.490 --> 18:06.050 trying to do. 18:06.090 --> 18:08.450 And we can just press Tab to fill it all the way in. 18:08.450 --> 18:09.370 But I'm not going to do that. 18:09.370 --> 18:17.450 I am going to type OpenAI API key equals no quote marks, no spaces, no spaces before or after and 18:17.450 --> 18:17.850 people. 18:17.850 --> 18:25.130 One common mistake is that sometimes people say open API key or OpenAI key, but it's not that it's 18:25.130 --> 18:26.810 OpenAI API key. 18:26.810 --> 18:28.290 And it's got to be exactly this. 18:28.290 --> 18:31.930 I think this is one of the only things in this course where every letter needs to be right. 18:31.970 --> 18:33.410 And so be careful. 18:33.410 --> 18:37.810 This is like 90% of the reason that people are frustrated in environment setup. 18:37.810 --> 18:39.450 Is this this very file. 18:39.890 --> 18:40.410 All right. 18:40.410 --> 18:47.090 What comes next is you simply paste in here exactly the key that came from OpenAI. 18:47.090 --> 18:55.980 And it should begin ESC dash proj dash, and then a bunch of letters and numbers with maybe an underscore 18:56.020 --> 18:56.940 symbol as well. 18:56.940 --> 18:58.180 And that should all come there. 18:58.220 --> 19:06.260 A bunch of them, not 123456780 as it has here in cursor, but a real key and not SK proj, and then 19:06.260 --> 19:09.220 another SK proj or anything like that that some people have done. 19:09.220 --> 19:10.580 It's got to be just right. 19:10.580 --> 19:14.340 Sorry to go on about it, but this is such a cause of problems. 19:14.340 --> 19:19.740 So so make sure that that key, the thing that's showing in purple here, is exactly the key that you 19:19.740 --> 19:20.820 took from open AI. 19:20.820 --> 19:22.340 And it should look perfect. 19:22.340 --> 19:26.180 And once you've done that you do command S to save this file. 19:26.180 --> 19:28.260 And you'll be in great shape. 19:29.340 --> 19:35.300 And at that point that will then be the end of step five of the environment setup. 19:35.300 --> 19:40.260 We will have done environment setup and we're good to get into the to the actual project. 19:40.300 --> 19:41.020 How about that. 19:41.020 --> 19:42.380 So congratulations. 19:42.380 --> 19:42.780 Thank you. 19:42.820 --> 19:44.100 Hopefully this is now all going to work. 19:44.100 --> 19:45.180 We'll soon find out. 19:45.180 --> 19:49.700 I will see you in the next lecture when we reconvene with team PC.
