https://stackoverflow.com/questions/74530990/how-to-run-multiprocessing-pool-code-in-python-without-mentioning-main-envir apparently that's useful only in windows

I don't think img2dataset really works in windows anyway

do you have another use case?

Have you tested that on Linux? I run this example script on Linux and got the error seems like https://github.com/rom1504/img2dataset/issues/176. After I put this code snippet into __main__, it works.

Yes it works for me.

What distribution are you using?
