How to print the performance of the training?

I used the haystack to train DPR with my own data, but there is no metric of the evaluation. how can I print the performance metric?

Hi,

It could be possible that the performance print outs aren't showing up due to the log-level setup you have.

You need to set it to be INFO as:

import logging
logging.basicConfig(format="%(levelname)s - %(name)s - %(message)s", level=logging.WARNING)
logging.getLogger("haystack").setLevel(logging.INFO)
