I traced back the issue. Its because pyphot made some major updates. I fixed the issue by using these line within the import statement chunks:

import pyphot
pyphot.config.set_units_backend('pint')

I achieved a similar fix to this by changing the .magnitude calls in phot_utils.py to .value. Not sure if this creates other unexpected issues. But has worked thus far.

Hiya, I'll look into this.

Thanks @spaceashley for tracing the issue
