ImportError: initialization failed when trying to import in python

[miccio-dk]

Hi all,
I'm trying to get ViSQOL to work through python
I followed all the installation steps and got the main script to work from the command line.
However, when I run the example code mentioned in the README, I hit this error:

>>> from visqol import visqol_lib_py
Add a python dependency on "@com_google_protobuf//:protobuf_python"
ModuleNotFoundError: No module named 'google'
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 1027, in _find_and_load
  File "<frozen importlib._bootstrap>", line 992, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed
ModuleNotFoundError: No module named 'google'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: initialization failed

It seems there's an extra dependency needed, but I'm having a hard time decyphering the error message.
What exactly am I missing?
Thanks in advance :)

Hi :-)

Apparently, there's a dependency on protobuf. Installing that package fixes the issue for me.
