Discrepancy between Github and installed versions of TTS

I have installed TTS into an environment using first
%pip install TTS --user
and then using
%pip install --user git+https://github.com/mozilla/TTS
in the Jupyter notebook. However the installed files do not match the ones on Github. For example TTS.utils.io does not include load_config.

The strange thing is that, from the error message I see the import command does not look for files in the environment but in the user\AppData\Roaming\Python… even though the kernel name on Jupyter matches the environment.

Pypi package TTS is maintained by coqui.ai, not Mozilla.
