Export catboost

[aclarkse]

Hello,

I am having trouble exporting the learned catboost model to a json format. The function provided in the notebook for this purpose (export_catboost_to_json) is outputting an empty file, and using the Catboost native functionality for this is not compatible with the rest of your codebase. Perhaps I am missing something related to what you mention in your README about the export_catboost binary that is needed. I am using a Windows system, so I am unsure how I should configure this. Any guidance would be much appreciated!

As a follow-up, I tried running this on WSL after keeping just the export_catboost_linux binary file in the root repository directory and adding this directory to my Ubuntu PATH environment variable, but I am still getting this error: sh: 1: export_catboost: not found
