CDSW - ModuleNotFoundError: No module named 'sklearn'

[#1]

hi
a newbie question...
i'm trying to follow the guide here (using CDSW 1.7) : https://www.cloudera.com/tutorials/building-a-linear-regression-model-for-predicting-house-prices.ht...

when i add the following 

import numpy as np
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.datasets import load_boston
from sklearn.metrics import mean_squared_error, r2_score

i get the ModuleNotFoundError :

ModuleNotFoundError: No module named 'sklearn'
ModuleNotFoundError             Traceback (most recent call last)
in engine
----> 1 from sklearn.model_selection import train_test_split

ModuleNotFoundError: No module named 'sklearn'

 how can i solve this?

thanks

You can do this:

!pip3 install sklearn

This will install the needed package. Note that ! is a magic command that executes the command not in your Python session but in the underlying OS environment.
