Broken datasets due to pandas API changes

[francois-rozet]

Hello @gpapamak,

Due to API changes in pandas, the GAS and HEPMASS datasets are not usable anymore. Notably, the DataFrame.as_matrix method has been deprecated since pandas=0.23.0 and the DataFrame pickling format of pandas<2.0 is not compatible with pandas>=2.0. There is also an issue with Counter.iteritems which is deprecated since Python 3.0.

I don't think modifying this repository to fix these issues is a good idea as it could break the code. Instead, I made a lightweight fork (francois-rozet/uci-datasets) of the repo's UCI datasets and wrote instructions to generate environment-agnostic .npy files containing the processed data. These .npy files can then be used without relying on the original code and its dependencies. I hope it's ok for you.

Thanks François for the bug report and for creating the fork! I agree, it's better to use your fork rather than modifying the repository. I added a comment to the README linking to francois-rozet/uci-datasets. Thanks again!

(Sorry it took me so long to respond... I don't actively maintain this repository anymore, so I barely check for issues.)

I had forgotten about that issue 😂 Thank you for taking a look.
