PyTorch 1.11 and 1.5. tried both.

The training .yml file don't set the learning rate of the estimater and you need add it into the .yml file, which is the reason of the 'NoneType'.

Then how to set?

Hello, do you solve it? Can you help me?

Sorry, but it can't be solved

Hello, You must assign value for "lr_E" in train section of .yml file (e.g. lr_E: !!float 4e-4)
