Issue with data prep

[AIAdventures]

Hi Jim!
Great project!
I am just having trouble with the prep data moudule.
Running it on linux mint.

andrewcz@andrewcz-PORTEGE-Z30t-B ~/Desktop/Numerai/numerai dataset/numerai_datasets (13)/numerai $ python prep_data.py
/home/andrewcz/miniconda3/lib/python3.5/site-packages/sklearn/cross_validation.py:44: DeprecationWarning: This module was deprecated in version 0.18 in favor of the model_selection module into which all the refactored classes and functions are moved. Also note that the interface of the new CV iterators are different from that of this module. This module will be removed in 0.20.
"This module will be removed in 0.20.", DeprecationWarning)

Many thanks for your help,
Andrew

The data format has changed since last year. There are some columns that need to be dropped.

I used this in tournament 72: feature_cols = ['feature'+str(i) for i in range(1, 22)]

Yes, this code is pretty out of date now. I may update in the future as time allows.

Hey @jimfleming I adapted parts of your code to work with the current format. I'll try sending a PR in the nearby future!
