Which app do I import to fix this error?

[ErnestTBass]

In the following snippet of code, I made a replacement:

import pandas as pd
import numpy as np
from sklearn.linear_model import LinearRegression
from sklearn.cross_validation import train_test_split
from sklearn.preprocessing import Imputer
import matplotlib.pyplot as plt

%matplotlib inline

The new code is

import pandas as pd
import numpy as np
from sklearn.linear_model import LinearRegression
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import Imputer
import matplotlib.pyplot as plt

%matplotlib inline

I replaced cross_validation in line 4 with model selection. It worked.



Now I get the following error when I run the code.

Error:
ImportError                               Traceback (most recent call last)
<ipython-input-11-8cc04663b4cc> in <module>
      3 from sklearn.linear_model import LinearRegression
      4 from sklearn.model_selection import train_test_split
----> 5 from sklearn.preprocessing import Imputer
      6 import matplotlib.pyplot as plt
      7 

ImportError: cannot import name 'Imputer' from 'sklearn.preprocessing' (/opt/conda/lib/python3.7/site-packages/sklearn/preprocessing/__init__.py)

Now I am confused since when I ran pip list and conda list I got that

sklearn 0.0

see attached screenshot. What import app covers this function?

It seems that I have sklearn 0.0 installed. That make no sense.

HowdoI correct this error. Is this handled by scikit-learn?

I am not sure what to do.

Respectfully,
