Description
This is removing all the tedious occurrences of
thread_wrapped_funcin the model examples. It is replaced by a minimalmp.Processwrapperdgl.multiprocessing.Process, which automatically handles the wrapping for you.From now on, for multi-GPU training we recommend the users to use
dgl.multiprocessing.Processinstead oftorch.multiprocessing.Process.
