There’s some missing context here. Is pandas_ta your package? If so, then you need to fix the bad import in core.py. The error message is pretty clear. Could you take a stab at resolving it, share what you tried, and what happened?
If it’s not your package, then you should open a bug report for the package developers, as they’re attempting to import a symbol that doesn’t exist in numpy.
Hello,
as the following error highlights: ImportError: cannot import name 'NaN' from 'numpy'
I think that you should import with lower-case, as in:
from numpy import nan as npNaN
