“AttributeError: ‘NoneType’ object has no attribute ‘shape’. View the submission for more details.”
how can i solve this error? thanks
We are looking into the issue, I will give you updates as soon as possible 
sure no problem 
Sorry for a little late reply but I looked into the notebook & the output .mp4 predictions, and found out that the videos the gen_predictions function is outputting contains only single frame.
And it’s because the predictions variable, from the model.nn_module.predict(image_batch) in gen_predictions function, has shape torch.Size([1, 1, 128, 128]) which represents a single image, the image_batch variable has also the same shape.
So i find out the main reason for this error is because you changed the batch size of test_loader from 23 ( in getting started code ) to 1. The main reason of using batch size of 23 in getting started code was because that each batch will represent each video. So, you will change to change your batch size to 23 and hopefully it will all work.
Let me surely know if you have any more doubts.
Cheers
