Could you teach me how to check shared memory on my machine?
My machine specs,

OS            : Windows 10 Pro
Processor : AMD Ryzen 7 2700X
RAM         : 16.0GB
GPU         : GeForce GTX 1050
Platform   : Anaconda (conda 4.10.1)
Environment : CUDA 11.3, Pytorch 1.8.1

Your suggestion worked! When I passed num_workers=1, “worker exited unexpectedly” appears again.
I have 64 DataLoaders. If any DataLoader has num_workers=1, “worker exited unexpectedly” appears.

I couldn’t find any suggestion about how to increase shared memory in Windows Environment. Could you help me again??
Thank you.
