As discussed [here](https://github.com/pytorch/pytorch/issues/43342),
adding in a Python-only implementation of the triplet-margin loss that takes a
custom distance function. Still discussing whether this is necessary to add to
PyTorch Core.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/39955
resolves https://github.com/pytorch/pytorch/issues/36323 by adding `torch.sgn` for complex tensors.
`torch.sgn` returns `x/abs(x)` for `x != 0` and returns `0 + 0j` for `x==0`
This PR doesn't test the correctness of the gradients. It will be done as a part of auditing all the ops in future once we decide the autograd behavior (JAX vs TF) and add gradchek.

Summary:
Fixes https://github.com/pytorch/pytorch/issues/43622
- Moves the model loading part of `torch.hub.load()` into a new `torch.hub.load_local()` function that takes in a path to a local directory that contains a `hubconf.py` instead of a repo name.
- Refactors `torch.hub.load()` so that it now calls `torch.hub.load_local()` after downloading and extracting the repo.
- Updates `torch.hub` docs to include the new function + minor fixes.

Summary:
These alias are consistent with NumPy. Note that C++'s naming would be different (std::multiplies and std::divides), and that PyTorch's existing names (mul and div) are consistent with Python's dunders.
This also improves the instructions for adding an alias to clarify that dispatch keys should be removed when copying native_function.yaml entries to create the alias entries.

As part of addressing #23232, this PR adds support for `broadcast_object_list` which is an API to broadcast arbitrary picklable objects to all the other ranks. This has been a long-requested feature, so would be good for Pytorch to natively support this.
The implementation approach follows a similar approach as https://github.com/pytorch/pytorch/pull/42189. The input is a list of objects to be broadcasted and it is in place, meaning all ranks part of the group will have their input list modified to contain the broadcasted objects from the src rank.
Note that the API is designed to match the tensor-based collectives other than supporting async_op. For now, it is a blocking call. If we see demand to support async_op, we will have to make more progress on merging work/future to support this.

Summary:
This PR needs discussion as it changes the behavior of `DataLoader`. It can be closed if its not considered a good practice.
Currently, the `DataLoader` spawns a new `_BaseDataLoaderIter` object every epoch,
In the case of the multiprocess DataLoader, every epoch the worker processes are re-created and they make a copy of the original `Dataset` object.
If users want to cache data or do some tracking on their datasets, all their data will be wiped out every epoch. Notice that this doesn't happen when the number of workers is 0. giving some inconsistencies with the multiprocess and serial data loaders.
This PR keeps the `_BaseDataLoaderIter` object alive and just resets it within epochs, so the workers remain active and so their own `Dataset` objects. People seem to file issues about this often.

Summary:
Add a max/min operator that only return values.
## Some important decision to discuss
| **Question** | **Current State** |
|---------------------------------------|-------------------|
| Expose torch.max_values to python? | No |
| Remove max_values and only keep amax? | Yes |
| Should amax support named tensors? | Not in this PR |
## Numpy compatibility
Reference: https://numpy.org/doc/stable/reference/generated/numpy.amax.html
| Parameter | PyTorch Behavior |
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------|
| `axis`: None or int or tuple of ints, optional. Axis or axes along which to operate. By default, flattened input is used. If this is a tuple of ints, the maximum is selected over multiple axes, instead of a single axis or all the axes as before. | Named `dim`, behavior same as `torch.sum` (https://github.com/pytorch/pytorch/issues/29137) |
| `out`: ndarray, optional. Alternative output array in which to place the result. Must be of the same shape and buffer length as the expected output. | Same |
| `keepdims`: bool, optional. If this is set to True, the axes which are reduced are left in the result as dimensions with size one. With this option, the result will broadcast correctly against the input array. | implemented as `keepdim` |
| `initial`: scalar, optional. The minimum value of an output element. Must be present to allow computation on empty slice. | Not implemented in this PR. Better to implement for all reductions in the future. |
| `where`: array_like of bool, optional. Elements to compare for the maximum. | Not implemented in this PR. Better to implement for all reductions in the future. |
**Note from numpy:**
> NaN values are propagated, that is if at least one item is NaN, the corresponding max value will be NaN as well. To ignore NaN values (MATLAB behavior), please use nanmax.
PyTorch has the same behavior

Summary:
Related to https://github.com/pytorch/pytorch/issues/38349
Implement NumPy-like functions `maximum` and `minimum`.
The `maximum` and `minimum` functions compute input tensors element-wise, returning a new array with the element-wise maxima/minima.
If one of the elements being compared is a NaN, then that element is returned, both `maximum` and `minimum` functions do not support complex inputs.
This PR also promotes the overloaded versions of torch.max and torch.min, by re-dispatching binary `torch.max` and `torch.min` to `torch.maximum` and `torch.minimum`.
