Flag --base_folder must have a value other than None.

I encountered this issue when I ran python train.py --data_dir $DATASET_PATH --base_folder $EXPERIMENT_PATH --gin_configs configs/test_vrig.gin. Below is the error log. What can I try to solve this? Thanks!

I got the same error message while training. Have you solved?

[Arjun Singh Kalra]

Same issue here. Any solutions yet?

Just replacing the None in train.py (46) with an arbitrary value fixes the problem for me.

flags.DEFINE_string('base_folder', 'base_folder', 'where to store ckpts and logs')

This solved the issue, thank you!
