I follow the instructions to install and run FILM. After running python models/train/train_seq2seq.py --data data/json_feat_2.1.0 --model seq2seq_im_mask --dout exp/model:{model},name:pm_and_subgoals_01 --splits data/splits/oct21.json --gpu --batch 8 --pm_aux_loss_wt 0.1 --subgoal_aux_loss_wt 0.1 --preprocess I get an error:

Preprocessing dataset and saving to pp folders ... This will take a while. Do this once as required.

Actually, there is data/json_2.1.0/tests_seen/trial_T20190909_042500_949430 directory, not data/json_feat_2.1.0/tests_seen/trial_T20190909_042500_949430. So, it seems the correct command is

python models/train/train_seq2seq.py --data data/json_2.1.0 --model seq2seq_im_mask --dout exp/model:{model},name:pm_and_subgoals_01 --splits data/splits/oct21.json --gpu --batch 8 --pm_aux_loss_wt 0.1 --subgoal_aux_loss_wt 0.1 --preprocess

Both variants are correct, but for those who don't want to download the Modeling Quickstart dataset it's easier to use just the Lite version, because images are not used in the preprocessing. Please correct me if I'm wrong, @soyeonm. Or maybe it should be mentioned that "You need the Modeling Quickstart dataset" so that people don't encounter the error in the title.
