1
00:00:00,000 --> 00:00:02,730
Okay. Let's look at installing some packages here.

2
00:00:02,800 --> 00:00:05,100
Honestly, we don't really need very much.

3
00:00:05,100 --> 00:00:08,400
We need TensorFlow, OpenCV and Keras.

4
00:00:08,400 --> 00:00:12,700
So here's what we're going to do, 'pip', because if you do 'pip -V',

5
00:00:12,700 --> 00:00:16,000
you should see that it's coming from, this terminal.

6
00:00:16,000 --> 00:00:19,400
Actually, it looks cool, but the highlighting isn't quite right. Now,

7
00:00:19,420 --> 00:00:21,390
it's coming from Python 3.7.

8
00:00:21,400 --> 00:00:24,030
So that's what you want, is just a more modern version of

9
00:00:24,040 --> 00:00:28,640
'pip'. I'm using pip 18.1, pip 20., something just came

10
00:00:28,640 --> 00:00:31,300
out. So I guess I'm technically using an older version of

11
00:00:31,300 --> 00:00:32,500
'pip', but that's still okay.

12
00:00:32,700 --> 00:00:39,700
So let's do 'pip install tensorflow', and we need TensorFlow 1.4,

13
00:00:39,700 --> 00:00:41,100
or newer, but less than 2.

14
00:00:41,100 --> 00:00:43,600
So let's do '1.*'.

15
00:00:44,010 --> 00:00:49,700
And we're also going to 'pip install opencv-python' and

16
00:00:49,700 --> 00:00:53,500
'keras'. And so this is just going to go off and fetch a bunch of

17
00:00:53,500 --> 00:00:55,400
stuff for us. All right,

18
00:00:55,450 --> 00:00:56,730
so that's all done installing.

19
00:00:56,740 --> 00:00:58,110
We need to install one more thing here.

20
00:00:58,120 --> 00:01:00,210
We probably could have done this in the last line as well, but

21
00:01:00,220 --> 00:01:02,040
let's just do it for funsies here.

22
00:01:02,180 --> 00:01:04,819
Let's clear that and make that just a little bigger.

23
00:01:04,819 --> 00:01:07,200
And so let's actually move that into the middle.

24
00:01:07,200 --> 00:01:11,400
Let's do 'pip install imageai --upgrade'.

25
00:01:13,200 --> 00:01:14,900
And so this is going to go and download.

26
00:01:14,910 --> 00:01:17,270
Basically, the main thing that's going to put all those other

27
00:01:17,270 --> 00:01:19,700
packages that we download, it's going to bring them all together for us.

28
00:01:19,880 --> 00:01:21,440
And there it is.

29
00:01:21,450 --> 00:01:24,450
There's the complaint about my 'pip' version.

30
00:01:25,000 --> 00:01:27,100
Now, lastly, we can do 'pip freeze',

31
00:01:27,100 --> 00:01:30,000
and this is going to show us all of our packages, and it doesn't

32
00:01:30,000 --> 00:01:31,500
really matter what they are at this point.

33
00:01:31,500 --> 00:01:33,020
We just know that these are all required.

34
00:01:33,030 --> 00:01:34,850
So let's go ahead and put these into a new file.

35
00:01:34,860 --> 00:01:37,790
So if we do 'ls -la', we can see we don't have any new files

36
00:01:37,790 --> 00:01:41,300
yet, but we can do 'pip freeze',

37
00:01:41,360 --> 00:01:44,240
and then that's the greater than sign, '>',

38
00:01:44,300 --> 00:01:47,300
and let's type 'requirements.txt'.

39
00:01:48,300 --> 00:01:49,500
'ls - la',

40
00:01:49,590 --> 00:01:53,000
and we can see we've got a new 'requirements.txt' file in there.
