Import error in pyvo

[gkakumari]

Quite new to coding and github in general. I am trying to import the pyvo for my work and it shows some import error. Any help would be appreciated.
import pyvo as vo

ImportError: cannot import name 'DALOverflowWarning' from 'pyvo.dal.exceptions' `

I am using this in a conda env

The import seem to work well in the version 1.3 in my system without any error so far.

Quite bizarre. So... can you have a look at ~/.conda/envs/gk/lib/python3.9/site-packages/pyvo/dal/exception.py and see if it contains class DALOverflowWarning(UserWarning): pass ? If it doesn't, there is a problem with your package. If it does, we have a new mystery...

Please try to uninstall and reinstall pyvo, this looks to be very much a local environment/installation issue rather than something inherent to the library itself.
