Summary:
Same as #14668, and was approved there.
ailzhang , please apply this patch to Horizon's `data_streamer.py`: https://gist.github.com/SsnL/020fdb3d6b7016d81b6ba1d04cc41459 Thank you!
Below is the original description at #14668:
As I am working on tasks in https://github.com/pytorch/pytorch/issues/13023, I realized how unreadable the code is because all functions to be run in multiprocessing must be at top global level. Adding more functionalities to `dataloader.py` will only make things worse.
So in this PR, I refactor `dataloader.py` and move much of it into `data._utils`. E.g., the `_worker_loop` and related methods are now in `data._utils.worker`, signal handling code in `data._utils.signal_handling`, collating code in `data._utils.collate`, etc. This split, IMHO, makes code much clearer. I will base my future changes to DataLoader on top of this.
No functionality is changed, except that I added `torch._six.queue`.

Summary:
Adds support for weak script modules created that get compiled to `ScriptModule`s once added as a submodule of a `ScriptModule`:
```python
weak_module
class Test(torch.nn.Module):
...
weak_script_method
def forward(self, x):
...
```

Instead of initializing CUDA immediately and executing them,
we wait until we actually initialize CUDA before executing.
To keep things debuggable, we also keep track of the original
backtrace when these functions are called, so we can inform
users where they actually called the seeding/state functions
(as opposed to the first time they actually initialized the
RNG).
Fixes#2517
