# 15. WARNING - Update

## Instructor Notes

Dear students,

in the following tutorial, the first line of code we will type will be:

```
    from sklearn.cross_validation import train_test_split
```

However the "cross\_validation" name is now deprecated and was replaced by "model\_selection" inside the new anaconda versions.

Therefore you might get a warning or even an error if you run this line of code above.

To avoid this, you just need to replace:

```
    from sklearn.cross_validation import train_test_split
```

by

```
    from sklearn.model_selection import train_test_split
```

and you will get no warning ;)

Hope you are having a great ML journey so far, I'll see you in the next tutorial.
