apex: TypeError: Class advice impossible in Python3

Question

i installed apex:

pip uninstall apex

My configurations are as follows:

• torch version 1.7.1
• python version 3.7
• cuda 11.0

I came across this error after running import pytorch:

TypeError: Class advice impossible in Python3. Use the @implementer class decorator instead.
