TypeError: is_file() got an unexpected keyword argument 'followlinks'

Reproduce the training entry point in tools/train_net.py, then trace checkpoint loading through cvpods/engine/runner.py and cvpods/checkpoint/checkpoint.py. Check the failing megfile SmartPath call and verify that training can load detectron2://ImageNetPretrained/MSRA/R-50.pkl without the reported TypeError.
