Hi,
Thanks for pointing this out.
Can you replace
inputBatch = pad_sequence([data[0] for data in dataBatch])
with
inputBatch = (pad_sequence([data[0][0] for data in dataBatch]),
pad_sequence([data[0][1] for data in dataBatch]))
in collate_fn
function defined in audio_visual/data/utils.py file and then try?
Please let me know if that resolves the issue. I will make this change in the next commit.

Hi, I replaced the line in question, but am getting a invalid comparison within the collate_fn:

I've pasted the current code of collate_fn below:
def collate_fn(dataBatch):
"""

"""
inputBatch = (pad_sequence([data[0][0] for data in dataBatch]), pad_sequence([data[0][1] for data in dataBatch]))
if None not in [data[1] for data in dataBatch]:
targetBatch = torch.cat([data[1] for data in dataBatch])
else:
targetBatch = None
inputLenBatch = torch.stack([data[2] for data in dataBatch])
if None not in [data[3] for data in dataBatch]:
targetLenBatch = torch.stack([data[3] for data in dataBatch])
else:
targetLenBatch = None
return inputBatch, targetBatch, inputLenBatch, targetLenBatch
from deep_avsr.
@arunm95, my latest pull request fixes both both of these issues:
For the invalid comparison replace:
if None not in [data[1] for data in dataBatch]:
with
if any(data[1] is None for data in dataBatch) == False

@lordmartian I am trying to reproduce the results you post in this (very nice) repo, could you provide more details regarding the hyper parameters (learning rate, no of words, n-epochs, ets.) for the different pre-training and training steps you followed for the AV model?
from deep_avsr.
@mlomnitz I have used the same values of hyperparameters which are given in the paper. I plan to include a document which lists down the important implementation details in the repo in the near future so that it will be easy for everyone to train from scratch. For now, you can go through the closed issues of the repo. I have mentioned many of the implementation details in the comments therein. Two people (as per my knowledge) had used the code and were able to achieve results close to mine. If something you would like to know is missing, kindly open an issue here and I'll be happy to answer.

@arunm95 you can use @mlomnitz 's solution. Please let me know if you face any other issues. Seems that my last commit has introduced some bugs. I'll go over the changes and rectify the bugs in the next commit.
from deep_avsr.
I have resolved both the bugs in the latest commit.
from deep_avsr.
@lordmartian That change resolved the error, however, I had set numworkers in the config file to 0 in order to avoid a mutliprocess error that was masking the original error. Setting the numworkers to anything other than 0 still causes this error.

This probably means that you are not using fork to start your
child processes and you have forgotten to use the proper idiom
in the main module:
if __name__ == '__main__':
freeze_support()
...
The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce an executable.
