1 00:00:02,730 --> 00:00:03,120 Okay. 2 00:00:03,120 --> 00:00:08,460 So in this case, as you can see I have my screen divided in one side. 3 00:00:08,460 --> 00:00:15,660 In the left side I have the website Jupiter or which is where we can learn about Jupiter notebooks. 4 00:00:15,660 --> 00:00:21,120 And if you click on install you will see that they are talking about Jupiter Lab, etc. etc. which is 5 00:00:21,120 --> 00:00:24,810 the new thing we are going to to demo today. 6 00:00:24,810 --> 00:00:31,740 And in the right side of the screen I have my terminal and in the terminal I am in the testing directory 7 00:00:31,740 --> 00:00:34,650 which is a directory new directory I have created. 8 00:00:34,650 --> 00:00:42,300 So here the first thing I'm going to do is I'm going to create a new virtual environment using pi env. 9 00:00:54,770 --> 00:00:57,770 Okay, so I have created the new virtual environment. 10 00:00:57,770 --> 00:01:01,280 Call my M444. 11 00:01:02,740 --> 00:01:04,720 I clear the screen. 12 00:01:04,720 --> 00:01:09,610 And now I'm going to activate this new, uh, virtual environment. 13 00:01:16,300 --> 00:01:20,950 Okay, so now I have the new virtual environment activated. 14 00:01:20,950 --> 00:01:22,870 If you see this. 15 00:01:23,500 --> 00:01:25,990 Uh, this is just one confirmation. 16 00:01:25,990 --> 00:01:33,550 We can clear the screen again, and now we can install Jupyter Lab in this new virtual environment. 17 00:01:42,120 --> 00:01:49,230 So the installation is not super fast, but is fast enough for us to see it in action. 18 00:01:49,230 --> 00:01:50,850 Uh, live. 19 00:01:51,270 --> 00:01:56,880 So you will see it will immediately finish the installation. 20 00:01:56,880 --> 00:02:03,510 Now we can clear the screen again and we can now open Jupyter Lab. 21 00:02:06,610 --> 00:02:13,570 When you click on this instruction, you will see that Jupyter Lab is going to open in the browser you 22 00:02:13,570 --> 00:02:14,590 have open. 23 00:02:14,590 --> 00:02:21,040 And here you see first it has created a localhost 8889. 24 00:02:21,040 --> 00:02:21,400 Okay. 25 00:02:21,400 --> 00:02:23,410 So we are using a local server. 26 00:02:23,410 --> 00:02:29,050 And here if you click here you can create a new notebook okay. 27 00:02:29,050 --> 00:02:30,880 So we can. 28 00:02:36,720 --> 00:02:39,330 Right, typical and executed. 29 00:02:39,780 --> 00:02:45,840 If you want to change the name, save Notebook as my name. 30 00:02:47,760 --> 00:02:55,230 Hey, here you can discard the untitled, but even if you discard it, it is going to still be here. 31 00:02:55,230 --> 00:02:57,750 So you can delete it like this. 32 00:02:57,900 --> 00:03:04,590 Okay, so if you click on this icon, you will open the directory you are in and you will see the different 33 00:03:04,590 --> 00:03:06,330 notebooks you have there. 34 00:03:06,330 --> 00:03:06,900 Okay. 35 00:03:06,900 --> 00:03:15,360 So I'm going to close this now and I will open it again just to demo you how to open a notebook that 36 00:03:15,360 --> 00:03:16,380 you have downloaded. 37 00:03:16,380 --> 00:03:21,270 For example, each of the notebooks you have from the from the program, the attached materials. 38 00:03:21,270 --> 00:03:21,810 Okay. 39 00:03:21,810 --> 00:03:25,170 So the first thing I come back to the terminal. 40 00:03:25,960 --> 00:03:31,450 Control C in order to shut down the server, I say yes. 41 00:03:32,590 --> 00:03:33,940 Clear the screen. 42 00:03:33,940 --> 00:03:41,320 And if I try to do something here, you are going to see that it says server connection error. 43 00:03:41,320 --> 00:03:44,770 So I just going to close this okay. 44 00:03:44,770 --> 00:03:51,970 And uh now I'm going to open it again from the terminal you see in the right side of the screen. 45 00:03:51,970 --> 00:03:53,650 So Jupyter. 46 00:03:54,740 --> 00:03:55,520 Lab. 47 00:03:56,780 --> 00:03:59,960 So it opens again, as you can see. 48 00:03:59,960 --> 00:04:03,770 And it it is opening in the last notebook I had opened. 49 00:04:03,770 --> 00:04:08,030 But I can close this, you know, and and open. 50 00:04:08,830 --> 00:04:09,790 Another one. 51 00:04:10,240 --> 00:04:10,750 Okay. 52 00:04:11,140 --> 00:04:15,100 A I can open several of them at the same time if I want. 53 00:04:15,130 --> 00:04:15,340 Okay. 54 00:04:15,340 --> 00:04:23,230 But the difference now is that I have tabs like this instead of having tabs in the browser like before 55 00:04:23,230 --> 00:04:24,160 with Jupyter notebook. 56 00:04:24,160 --> 00:04:26,740 So this is how Jupyter Lab works. 57 00:04:26,740 --> 00:04:34,570 The only thing you need to remember is that if you have the Jupyter server open like this, you cannot 58 00:04:34,570 --> 00:04:41,110 use the terminal in order to make other operations like like install new modules, whatever. 59 00:04:41,110 --> 00:04:45,730 So if you want to use the terminal, what you are going to do, you come to the terminal and you open 60 00:04:45,730 --> 00:04:47,140 a new window okay. 61 00:04:47,140 --> 00:04:49,900 So open a new window of the terminal. 62 00:04:49,900 --> 00:04:57,640 Go to the same directory and there you can well of course, uh, activate the virtual environment. 63 00:04:57,640 --> 00:05:03,130 And then you can install more modules or do whatever operation you need you need. 64 00:05:03,130 --> 00:05:05,950 So as you can see, it's very easy. 65 00:05:05,950 --> 00:05:13,030 Uh, but we thought that since there was a little change, it was interesting to share this with you.
