Dataloaders - Due to IPython and Windows limitation, python multiprocessing isn't available now

Part 1 (2019)

I use a windows machine and I tried to run the following code:

dls = bears.dataloaders(path)

I encountered the following msg:

Due to IPython and Windows limitation, python multiprocessing isn’t available now.
So number_workers is changed to 0 to avoid getting stuck

How shall i deal with it?

Either run Linux or stay on windows with your current solution

fastai directly using Jupyter notebook in Win10 will occur this limit.It can go on if u wait.But it would operate slowly and it would influence the performence of the GPU.There is no mistakes when it runs in macOS or Linux, which proves the Window is still not suitable to do the deeplearning work to a extent.
