error: module multiprocessing.util' has no attribute '_flush_std_streams

[hktxt]

hey~~~
I run your code but error shows up.....
it seems like cannot enumerate trainloader. once do enumerate(trainloader), error appears: "module multiprocessing.util' has no attribute '_flush_std_streams"
However, change the NUM_WORKERS to 1, it disappeared..., but that's not what I want...

I dont know how to solve it
