Please, try to use this command for databse initialization.
flask --app app init-db
There are probably some naming mismatch in the installation guide. Please tell me if it worked for you.

thanks, later tried flask --app app db init and that worked. May be because version mismatch, in my env installed Flask-Migrate==4.0.7
but after bash run.sh, pages were launched, but setting imagedir ,no response returned, no error log printed, unable to further debug
all logs are like this

Loading model: ./models/MERT-v1-95M
INFO  [alembic.runtime.migration] Context impl SQLiteImpl.
INFO  [alembic.runtime.migration] Will assume non-transactional DDL.
INFO  [alembic.env] No changes in schema detected.

Really not sure what the problem might be here. What OS do you use?
As a temporary fix, you can configure "media_directory" folders directly in the config.yaml file.
