Or maybe the OP is running 32-bit Python but the code needs >2GB. If
that's the case then using 64-bit Python might fix it, assuming that
it's a 64-bit machine.
Yes, it is 64.
Excuse me, can you explain how I can fix it?
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.
