    • [CodeGen][CUDA] Improve CUDA vectorizer (#4736) · 2630ffcb 
      - Fixes issues to enable fp16 vectorizer. Now correct packing and
  unpacking CUDA code will be emitted. Enabled more unit tests.

- Do not emit code to read the first lane from an undef variable

  int _3;
  _3 = _3 & ~(0x000000ff << 0) | ...

  and emit the following code instead:

  _3 = (((0x000000ff & (_1 >> 0))+(0x000000ff & (_2 >> 0))) << 0);

  Note that nvcc 10.2 is forgiving and emits the same code for both cases.
  A warning appears in test_codegen_cuda.py.

    • GitHub Action lint Python code for syntax errors (#4688) · bd17baa2 
      * GitHub Action lint Python code for syntax errors

https://flake8.pycqa.org/en/latest/user/error-codes.html

On the flake8 test selection, this PR does _not_ focus on "_style violations_" (the majority of flake8 error codes that [__psf/black__](https://github.com/psf/black) can autocorrect).  Instead these tests are focus on runtime safety and correctness:
* E9 tests are about Python syntax errors usually raised because flake8 can not build an Abstract Syntax Tree (AST).  Often these issues are a sign of unused code or code that has not been ported to Python 3.  These would be compile-time errors in a compiled language but in a dynamic language like Python they result in the script halting/crashing on the user.
* F63 tests are usually about the confusion between identity and equality in Python.  Use ==/!= to compare str, bytes, and int literals is the classic case.  These are areas where __a == b__ is True but __a is b__ is False (or vice versa).  Python >= 3.8 will raise SyntaxWarnings on these instances.
* F7 tests logic errors and syntax errors in type hints
* F82 tests are almost always _undefined names_ which are usually a sign of a typo, missing imports, or code that has not been ported to Python 3.  These also would be compile-time errors in a compiled language but in Python a __NameError__ is raised which will halt/crash the script on the user.

* Force a retest

* Rename start_rpc_server_to_tracker.py to start_rpc_server_to_tracker.sh

This is a bash file, not a Python file.
