Use ==/!= to compare str, bytes, and int literals

flake8 testing of https://github.com/cgnorthcutt/benchmarking-keras-pytorch on Python 3.7.1

E901,E999,F821,F822,F823 are the "showstopper" flake8 issues that can halt the runtime with a SyntaxError, NameError, etc. These 5 are different from most other flake8 issues which are merely "style violations" -- useful for readability but they do not effect runtime safety.

• F821: undefined name name
• F822: undefined name name in __all__
• F823: local variable name referenced before assignment
• E901: SyntaxError or IndentationError
• E999: SyntaxError -- failed to compile a file into an Abstract Syntax Tree

This is reasonable. Thanks for the style suggestion. Migrating and closing.
