TypeError: cannot serialize '_io.BufferedReader' object #25
Comments
@TSMLuL I'm also working through this repo! I've found the issue (but don't know why it's an issue). In WavenetTrainer.train(), do this: I don't know how to do new lines in code but anyways main point is comment out the num_workers line. (Sauce) |

Hi!
I am currently trying to execute the WaveNet_demo.ipynb file which you kindly provided for download.
When executing the
trainer.train(batch_size=16, epochs=10)
part, I unfortunately run into an error message like thisTypeError: cannot serialize '_io.BufferedReader' object
(full error message below).Do you know why this could be or how to fix it? I did not find any related threads on the internet unfortuately...
I am on a windows 10 machine, python 3.7.3, torch version 1.0.1.
Cheers and thanks a lot
