Are you using a 32-bit version of Python or a 64-bit version of Python?

If you're not sure, try this from Python:

 >>> import sys
 >>> sys.maxsize.bit_length()

I get 63 because I'm running a 64-bit version of Python 3.

On Windows you can install multiple versions of Python side-by-side. I 
don't know the procedure for Linux or MacOS.

If you're currently using 32-bit Python, you can install the 64-bit 
version in a folder next to the folder of the 32-bit version (I have 
C:\Python39 and C:\Python39-32, for example). Then install any other 
packages you need for the new version.
