Error when trying to execute code in real_data_example.ipynb: module 'datasets' has no attribute 'GetDataset'

[fboehm]

I'm encountering an error when I try to run code in the file real_data_example.ipynb. Specifically, I encounter the error in the line:

X, y = datasets.GetDataset(dataset_name)

I appreciate any suggestions or assistance that you might provide.

I misunderstood the use of python's import command. I see now that the repository contains a file, datasets/datasets.py that specifies the code for GetDataset. I apologize for my confusion.

I'm now getting this error when trying to run the same code.

I see now that sklearn.preprocessing.Imputer is deprecated in current versions of sklearn.

Current versions of sklearn have sklearn.impute.SimpleImputer. I imagine that the code in the jupyter notebooks should be updated to reflect this.
