Nd2 image file reader - 'pyav_reader' problem

[gkanfer]

I am trying to run the library nd2reader for reading Nikon image files (Nd2)

The command

from nd2reader import ND2Reader 

and I got this error:

---------------------------------------------------------------------------

If I were you, I would first check:

1. If the version of pims you have is compatible with your version of nd2reader (I'd probably look at what nd2reader says it needs in the requirements and/or setup.py files, as well as double checking that you have the most recent version of nd2reader)
2. If you installed the optional dependencies to use pims with PyAV (see this page in the docs, you'll need ffmpeg and PyAV installed)
