GluonCV ImportError: cannot import name 'is_np_array'

I'm trying to set up a GluonCV in a jupyter notebook in a virtual environment. For some reason whenever I try to import GluonCV I get this error:

ImportError                               Traceback (most recent call last)

ImportError: cannot import name 'is_np_array'

I've tried using the same files that work on Google Collaboratory but I still get that error. I've tried reinstalling gluon and all that stuff in all manners. No idea what's going on. For convenience I really need this to work.

Solution

I resolved this error by installing the compatible versions of mxnet and gluoncv.In my case I had installed mxnet with with gluoncv native, that resolved the error.
