Installing Python Google Assistant SDK Backtracks to Unusable Older Version

Question

I am trying to install Google Assistant SDK on Windows following instructions at:
https://github.com/googlesamples/assistant-sdk-python/tree/master/google-assistant-sdk

It looks like some requirement not being satisfied is causing the installation to backtrack to version 0.3.3. Install log is pasted below. Can someone help me debug this?

Using command:
pip install --upgrade google-assistant-sdk[samples]

Ouput:
