Hi
I am receiving the following RuntimeError
RuntimeError: isInt() INTERNAL ASSERT FAILED at /tmp/pip-req-build-xd7oc4a9/aten/src/ATen/core/ivalue.h:221, please report a bug to PyTorch. 
The above operation failed in interpreter, with the following stack trace:
at /network_extended.py:49:30
        outputs = []
        for i in range(len(inputs)):
            state = self.cell(inputs[i], state)
                              ~~~~~~~~ <--- HERE
            outputs += [state]
        return torch.stack(outputs)

when attempting to train on a machine with this environment 1. Note that I am executing in a Singularity container built using Nvidia’s pytorch_20.01-py3 image. As such, whilst the Tesla V100 allocated to the system appears unavailable in the above dump, it is very much available and works with other PyTorch models trained the same way.
However, curiously, when executing the exact same code on an older Windows 8.1 machine with this environment, everything works as expected. I can thus only assume that it is due to the specific environment on my Linux machine as opposed to my code.
I have for this reason opted for writing here as opposed to submitting an issue. I am naturally happy to close this thread and submit an issue with additional information if that is more appropriate.
Any thoughts on what this could be are greatly appreciated!
Thanks!
