I had this issue before but that was using peterjc’s unofficial window version. The solution is really simple you just have to change num worker to 0 and everything works. Out of curiosity, I tried to change num worker to above 0 in my data loader after installing the official 0.40 windows release and I still have the error. How do I use more than 1 worker?
if __name__ == '__main__': # Your code
to safely use multi-processing.
@inkplay Besides, you may have used something in the data loading process that may be unsupported in
multiprocessing on Windows, such as lambda functions, nested functions or classes and etc.
Thanks for the reply I did not know what!
Thanks for the info!
