357160e68e [DataPipe] Unifying API - removing nesting_level argument from FilterIterDataPipe (#69391)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/69391

As part of the efforts to unify the APIs across different data backends (e.g. TorchData, TorchArrow), we are making changes to different DataPipes' APIs. In this PR, we are removing the input argument `nesting_level` from `FilterIterDataPipe`.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/65220

Fixes #65221

- Remove deepcopy from Mapper to support file handles
- Convert `IterableWrapper` to deepcopy iterable instance within each iterator to prevent in-place modification (different data per epoch)
- Convert `IDP` to `IterableWrapper` in test_datapipe.py
- Refine the variable names (prevent using `dp` that is module reference)

c625f971d3 [DataPipe] Make TarArchiveReader and ZipArchiveReader accepts FileSream with attempt to close and additional warning (#64788)
Summary:
ghstack is not working for the second commit so I'm manually creating this PR for now. Please only look at changes related to the second commit in this PR (there is a PR for the first commit).

This PR removes TarArchiveReader's dependency on FileLoader DataPipe, by allowing it to use a IterDataPipe of path names as input rather than a tuple of path name and a stream.

It also adds additional tests to ensure that the DataPipe is functioning properly when it is read multiple times or reset half way through reading.

The whole stack fixes https://github.com/pytorch/pytorch/issues/64281 - issues related to unclosed buffer stream.

c19adfff54 [DataLoader] Introduce ConcatMapDataPipe functional datapipe (#61010)
Summary:
As part of https://github.com/pytorch/pytorch/issues/57031, this PR adds the ConcatMapDataPipe functional datapipe for the MapDataPipe class.

We may need to discuss how to treat the datapipes with no valid length. For now, I just use them as if they have infinite length and the `__getitem__` could not go pass them.

Thank you for your time on reviewing this~

a120a12ab4 [Bootcamp][pytorch]Add WebIterDataPipe and ToBytesIterDataPipe to the datapipes. (#59816)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/59816

Add two new DataPipes, one for getting web file urls to yield streams and one for getting streams to yield bytes.

Test Plan:
Add test_web_iterable_datapipe in test/test_datapipes.py. The test initiates a local http server for serving test files. Test below locally ok.
1. create and load 16M localhost file urls (each of size 10 Bytes)
2. create and load a 64GB localhost file
in the unit test, for sake of testing time, disabling both stress test and large file test

1b578c4bf5 [DataLoader] Close byte stream explicitly (#58938)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/58938

When run `test_datapipe.py`, python `gc` would report lots of `ResourceWarning`s due to unclosed stream. It's not only annoying, there are two potential problems:
- Performance regression because `gc` requires additional memory and computation to track reference
- Python `gc` runs periodically so we many encountered an error of too many open files due to OS limitation
To reduce the warning:
- Explicitly close byte stream
- Modify `test_datapipe.py` to use context manager

Small fix:
- Reorder import in `test_datapipe.py`

Further investigation:
Can we directly use context manager in `LoadFileFromDisk` and `ReadFileFromTar` to eliminate this Error?
- Probably no. It's feasible only if the pipeline is synchronized and without prefetching. When we enable these two features, the scope guard of the context manager doesn't work.
- We may need to implement some reference counter attached to these file byte stream to close by itself.

As part of https://github.com/pytorch/pytorch/issues/57031, this PR adds the `MapMapDataPipe` functional datapipe for the `MapDataPipe` class.

Usage:
```
def fn(x):
    return x * 10

dp = CountingDataset(n=10)
dp.map(fn)
```

5c696443c7 [DataLoader] Modfity construct_time_validation to argument_validation (#55836)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/55836

Change construct_time_validation to argument_validation as we should provide users the flexibility to use this decorator over all different functions, which are required with type validation.

It can also work as a construct-time validation
```py
class ExampleDataPipe(IterDataPipe):
    argument_validation
    def __init__(self, dp: IterDataPipe[int]):
        self.dp = dp

    ...
```
Notebook is also updated.

b58a7c95aa [DataLoader] Raise detailed Error for ForwardRef type (#57824)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57824

Implement type check for string type. Re-raise detailed exception at compile time.
```py
>>> class InvalidData(Generic[T_co], NamedTuple):  # Invalid generic namedtuple in Python typing
...     name: str
...     data: T_co

class DP(IterDataPipe['InvalidData[int]']):
...     pass
TypeError: InvalidData[int] is not supported by Python typing
```

Add `__type_class__` attribute to class, which optimizes the static checking flow by reducing checking times.
```py
>>> class DP1(IterDataPipe[Union[int, str]]):
...     pass
>>> class DP2(DP1[int]):
...     pass
>>> list((cls, getattr(cls, '__type_class__', None)) for cls in DP2.__mro__)
[(<class '__main__.DP2'>, False), (<class 'abc.DP1[int]'>, True), (<class '__main__.DP1'>, False), (<class 'abc.IterableDataset[typing.Union[int, str]]'>, True), (<class 'torch.utils.data.dataset.IterableDataset'>, False), (<class 'torch.utils.data.dataset.Dataset'>, None), (<class 'typing.Generic'>, None), (<class 'object'>, None)]
```
Among the class of `DP2`'s MRO, only `DP2`, `DP1` will be static checked when `__type_class__` is `False`. `abc.DP1[int]` and `abc.IterableDataset[typing.Union[int, str]]` will be ignored since they are just a class with typing.

## Future
When Python 3.6 is deprecated, using TypeAlias rather than TypeMeta can eliminates the usage of `__type_class__` attribute.
