I got this error while trying to install and run tensorflow for gpu following this tutorial https://www.youtube.com/watch?v=hHWkvEcDBO0 I have python 3.7.4 What am I doing wrong here, is it a version issue?

Answer 1

According to [Python.docs]: class typing.OrderedDict(collections.OrderedDict, MutableMapping[KT, VT]) (emphasis is mine):

New in version 3.7.2.

True
Done.

There it is: Python 3.7.4 from Anaconda, whose typing module has OrderedDict.
The only logical conclusion (well, excluding a broken environment with an messed up typing version) one could draw is that you're actually running Python < v3.7.2.
The fix is running Python >= v3.7.2.
