Fixed #592

[bfirsh]

Nice, thanks! This is an intriguing problem. Do you know why this might be fixing this issue?

It seems to me that the "dependency hell" is the root cause since tensorflow==2.5.0 requires typing-extensions~=3.7.4 and starlette requires typing-extensions as Any but it asks for ParamSpec which has appeared since v4.1.0 https://github.com/python/typing/blob/master/typing_extensions/CHANGELOG.md

We can take a look at the pipdeptree output
