Hi,

I have tried many versions of Xgboost with our python 3.7 environment. But none of them working (see below for error messages). I am wondering maybe someone know some specific old version Xgboost works with python 3.7.

Thanks

For Xgboost versions >=1.7.0, I got "ERROR: Package 'xgboost' requires a different Python: 3.7.12 not in '>=3.8'". 

For version<1.7.0, I got the following error:
copying xgboost/CMakeLists.txt -> build/lib.aix-7.1-3.7/xgboost
