Thanks - I am able to launch 'py' from the command prompt and it gives me the python versions installed in my machine from python.org website. However, when I am trying to execute a python program from command prompt, I am getting the error below. I had reinstalled python packages (numpy, pandas) but it didn't resolve the issue. Any help would be appreciated. Original error was: No module named 'numpy.core._multiarray_umath'

I have Python 3.6 from Python.org and here a 'py.exe -0' gives: Requested Python version (0) not installed But using 'py.exe -0' from Python 3.9 correctly gives: -3.6-32 * -2.7-32 -- --gv -- https://mail.python.org/mailman/listinfo/python-list -- https://mail.python.org/mailman/listinfo/python-list
