What does this PR do?
Skip all the tests in
test_sharded_checkpoint.py
IF pytorch 1.13 is not installed. This is because these tests use FSDP and if Composer uses FSDP and pytorch 1.13 is not installed, the process will fail.These failing tests do not mean anything will break for user, it just means the tests fail when they shouldn't
TLDR: add a pytest.skip call (conditional on pytorch 1.13 is not being installed) to all tests in
test_sharded_checkpoint.py
