Hi, this is not normal. It should not be as slow as this. Can you let me know your configs, like the batch_size, decoding graph, etc?

The normal training speed should be like :18:19.000Z /container_e09_1568924618046_16257_01_000002: [1,0]:=> loaded checkpoint '/datablob/users/lial/pykaldi2/seed_model/model.6.tar' 2019-12-16T19:21:47.000Z /container_e09_1568924618046_16257_01_000002: [1,0]:Epoch: [0][ 0/70311] Time 205.143 (205.143) Loss 5.7131e+00 (5.7131e+00) grad_norm 2.5644e+03 (2.5644e+03) 2019-12-16T19:22:13.000Z /container_e09_1568924618046_16257_01_000002: [1,0]:Epoch:...

Hi @yotam319, thanks a lot for your advice and code sample. Yes, what you said definitely makes sense. Previously, I only did a vanilla version of LF-MMI in the toolbox,...

That is a good question. I missed that. Indeed, for the current implementation, the CE regularization does not work in my experiments. It is a bit unclear to me why...
