Some questions about "ut preprocess"

[ljyljy]

I have skipped the 'ut preprocess' command and used the 'ut train' command to train directly before, and there is no error.

However, when trying the 'ut preprocess' command, I encountered some problems.
I don't quite understand the use of 'ut preprocess'. Is it related to settings such as YAML? > <
How to set up correctly to successfully perform 'ut preprocess'?
THX a lot！

my folder：
demo->my_utime_project2->...
->datasets->processed->dcsm

command:
ut preprocess --out_path ../datasets/processed/dcsm/processed_data.h5 --dataset_splits train_data val_data --overwrite

error screenshot:
（1）Use RandomChannelSelector (default in YAML)

（2）Use select_channels: ['C4-M1', 'E1-M2'] in YAML:

ut preprocess --out_path ../datasets/processed/dcsm/processed_data.h5 --dataset_splits train_data val_data --overwrite
