* fix code style

* fix ctest

* temp save

* save change

* change by YSL

* final change by ysl

* fix ci

* fix code style

* delete unuse code

* change by ysl

* use yapf to format all python file

* yapf exclude two unittests file for they rely on writing and reading file, and format will break them

* disable diff_py_file because too many diff files cause command following failed

* fix test of affine_grid with rocm
