I have the following error :

Finished loading 2591 records with 23 columns.

Please post your configuration here, at least the "feature_sets" list. It seems that this section is not correctly formatted. A typical format for feature_sets is in the App.config:

"feature_sets": [
    {"column_prefix": "", "generator": "binance_main", "feature_prefix": ""}
]

I have resolved the issue by manually creating the directories (DATA_ITB/BTCUSDT etc...).
It's ok now but I have to work again on this project that seems very interesting.
I'll let you know if I have issues when I work on it again.
Thank you.
