Getting Error: TypeError: join() argument must be str or bytes, not 'NoneType'

I followed your instruction on training and added 2 images in example_experiment (1 of brad pitt and 1 of lenna soderberg). I also hard coded the full directory paths within example_experiment.py in case there was a problem there.

Here is my error:

The above exception was the direct cause of the following exception:

Any ideas?

looking at the stack trace you've provided my first assumption is that you don't have WORKDIR env variable declared in your .env file (the code crashes in datasets_builder here: https://github.com/Giphy/celeb-detection-oss/blob/master/model_training/preprocessors/datasets_builder.py#L116)
just wondering have you created .env file in the root dir as described in README?
