I also encountered this problem. l will have a try. Thanks!

@XYAskWhy After I executed `python main.py -- prepare_masks`, this error still exists. What columns are in your stage1_metadata.csv ? There are only the following columns in my file： ImageId, file_path_image,...

I re-executed commands `python main.py -- prepare_masks` **and** `neptune experiment run main.py -- prepare_metadata \ --train_data \ --valid_data \ --test_data` **in order**. However, there is still no **file_path_mask_eroded_0_dilated_0** column in...

This is my neptune.yaml: > data_dir: /home/shenshen/Programs/mc_data > meta_dir: /home/shenshen/Programs/mc_data > **masks_overlayed_dir: /home/shenshen/Programs/mc_dat_eroded_2_dilated_3** > masks_overlayed_eroded_dir: /home/shenshen/Programs/mc_dat_eroded_2_dilated_3 > experiment_dir: /home/shenshen/Programs/open-solution-mapping-challenge I am not sure if the `masks_overlayed_dir` setting is correct. @jakubczakon

OK. Thanks! After `python main.py -- prepare_masks`， folder **mc_dat_eroded_2_dilated_3** was generated. According to my statistics, it takes up 123.1GB of space. When was this folder generated? **masks_overlayed_dir: /home/shenshen/Programs/masks_overlayed/**

Thank you very much! I understand. I did not create _masks_overlayed_ folder before prepare_masks. So how is this item set up? When is the content in it generated? **masks_overlayed_eroded_dir: ???**

I finally configured correctly！ Unfortunately, I did not find the column file_path_mask_eroded_0_dilated_0 in the generated stage1_metadata.csv file... The first time I created metadata, it took several hours, but now it's...

 This is the head of stage1_metadata.csv. No similar column appears.

Yes, I have changed the masks_overlayed_dir in the neptune.yaml and delete stage1_metadata.csv. Then I ran the **prepare_metadata** again. The result is the same as in the picture above.
