ERROR IN INSTALLING FastTreeSHAP

Hi Team,

I am not able to install the FastTreeSHAP library in Kubeflow, facing below error -

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for fasttreeshap

You should consider upgrading via the '/usr/bin/python -m pip install --upgrade pip' command.

Kubeflow で Python 3.9 を使用して fasttreeshap/cext/_cext.cc をビルドしている際に失敗が発生します。pip のインストールを再現し、その環境で Python.h を gcc が利用できない理由を調査してください。パッケージがそこで正常にビルドおよびインストールできれば完了です。
