To enable, set the train function arguments to be func(config, checkpoint_dir=None). 2021-07-05 10:27:01,095 WARNING tune.py:411 -- Tune detects GPUs, but no trials are using GPUs. To enable trials to use GPUs, set tune.run(resources_per_trial={'gpu': 1}...) which allows Tune to expose 1 GPU to each trial.

The problem is due to path length limitations on windows. You can enable long path by following instructions on this page: https://www.howtogeek.com/266621/how-to-make-windows-10-accept-file-paths-over-260-characters/
