I think my problem was same with you, using data_thcs30 data set, but infer got nothing, do you get this resolved?
I am working on a prototype now based on the thchs30 data set now and running into similar issue here.
I am using
ân_hidden 100
âlearning_rate 0.0001
and batch size as 3 to train the model.
Have you figured out how to solve the problem?
