Hi,
I installed ROOT 6.26 through Homebrew (brew install root) and it works fine. I later installed python with anaconda distribution and the version is 3.9.7, which also works fine with all the common python modules.
However, running the command import ROOT on python prompt gives the following error:
ModuleNotFoundError: No module named 'ROOT'
When I source /opt/homebrew/Cellar/root/6.26.02_1/bin/thisroot.sh and then try to import ROOT from python, I get the following error instead:
Traceback (most recent call last):

ImportError: Failed to import libcppyy3_9. Please check that ROOT has been built for Python 3.9
Any solution would be much appreciated.
