A probable typo in the code?

[DRfn1234]

Hello!When I try to train the model, there is an error said AttributeError: 'VideoBlock' object has no attribute 'get_block_block' and there is no get_block_block in class VideoBlock in videosubnetwork.py. Can you help fix this? Thanks in advance.

I change the get_block_block to get_video_block and hope it'll be correct. But another error occurs that TypeError: stack(): argument 'tensors' (position 1) must be tuple of Tensors, not NoneType in def on_validation_epoch_end(self): after I add validation_step_outputs=None indef initin order to solve the problem in #8. Do you know how to fix it?

My guess would be that the input is none causing this error. You can test the model individually to see if the inputs and outputs are correct.

Which value should I set to the validation_step_outputs? Because it requires an input.
