Xgboost_gpu for Windows is not available on conda anymore?

I have followed the official instructions to install py-xgboost-gpu on Windows, say, entered ‘conda install -c conda-forge py-xgboost-gpu’ in Anaconda prompt window, but it says no package found on this channel.

I then searched py-xgboost-gpu on anaconda.org and found that this package is listed as only support Linux platform: https://anaconda.org/conda-forge/py-xgboost-gpu

Why? And how can I install the py-xgboost-gpu to my system without building from source?

It appears that the py-xgboost-gpu package has never been available on Windows to begin with.

how can I install the py-xgboost-gpu to my system without building from source?

For now please use pip to install XGBoost on Windows:

pip install xgboost

I submitted https://github.com/dmlc/xgboost/pull/8127 to indicate that py-xgboost-gpu is only available on Linux.

Oh… I thought it is available because I have seen a ‘check’ mark in the table under the ‘Stable Release - Python’ section in this offical webpage: https://xgboost.readthedocs.io/en/latest/install.html#python

The check mark is only applicable for the pip package.
