How to install XGBoost or LightGBM on Windows? I'm a Windows user and would like to use those mentioned algorithms in the title with my Jupyter notebook which is a part of Anaconda installation.

I've tried in anaconda promt window:

pip install xgboost


which retuned:


  Could not find a version that satisfies the requirement xgboost (from
  versions: ) No matching distribution found for xgboost


Likewise, I've tried:

conda install lightgbm


which returned:


  Solving environment: failed
  
  CondaHTTPError: HTTP 000 CONNECTION FAILED for url
  https://repo.anaconda.com/pkgs/r/noarch/repodata.json.bz2 Elapsed: -


Help would be appreciated.
Follow this XGBoost installation guide: https://xgboost.readthedocs.io/en/latest/build.html

If you are using python3 then make sure that you run: pip3 install xgboost

To fix the problem with lightgbm on windows try installing OpenSSL first, refer this: https://www.cloudinsidr.com/content/how-to-install-the-most-recent-version-of-openssl-on-windows-10-in-64-bit/n
