Move autograd metadata from VariableImpl to TensorImpl (#13827)

Summary:
Changes originally in this PR:
1. Move Variable::Impl data members into TensorImpl as `AutogradMeta` struct
2. Change Variable::Impl functions to use data members in `AutogradMeta` struct
3. Add `shallow_copy_and_detach()` function to each subclass of TensorImpl
4. Do shallow copy when the user calls `make_variable(tensor)` / `make_variable_view(tensor)` / `variable.set_data(tensor)` / `variable.detach()`

Changes moved from https://github.com/pytorch/pytorch/pull/13645:
1. Add a flag to Variable to disallow size/stride/storage_ptr changes from in-place operations such as `resize_` / `resize_as_` / `set_` / `transpose_`, and set this flag to true when people call `tensor.data` in Python.
2. Write text in the docs to actively discourage changing the shape or storage of `tensor_detached` and expecting `tensor` to also be updated.

James Reed [Fri, 21 Dec 2018 18:32:57 +0000 (10:32 -0800)]
Direct FBGEMM integraton into ATen (#13777)

Summary:
This PR implements infrastructure for post-processing a model to apply int8 quantization to its `nn.Linear` modules. Highlights of the implementation:

1) Inputs and outputs are `float` (quantized and packed internally), but the weight is quantized and packed ahead of time for efficiency. This implementation performs well in small-batch size GEMM calls. It should not be considered a general-purpose quantized GEMM kernel.
2) Weight packing is dependent on machine architecture (e.g. vector register width), so it is done just-in-time. Concretely, it is done on model load for the weights and it is done during operator execution for the input value.
3) Biases are unquantized
4) We fail loudly if we are attempting to run this on a machine that does not support FBGEMM. This is because we do not want a model's numerics to differ based on which machine it is run on. A model containing these FBGEMM ops *must* be run with FBGEMM

The API can be seen in the added test case. Highlights are:
1) `torch.jit.quantized.quantize_linear_modules` walks the module hierarchy of the passed-in Module and replaces all `nn.Linear` modules with a new `QuantizedLinear` module, which encapsulates the behavior described above.
2) `_pack()` and `_unpack()` script methods are present on `QuantizedLinear` modules. These methods should be called before serialization and after deserialization, respectively. This ensures that the weight matrix is properly packed for the running machine's architecture. Note that in the long term, we would like to move toward a more Pickle-style serialization technique, rather than having these explicit methods that mutate member values. This is blocked on being able to assign attributes in a ScriptMethod, among other things.

5 years agoAdd option to automatically handle unsorted variable-length sequences in RNNs (#15225)
Richard Zou [Fri, 21 Dec 2018 01:34:41 +0000 (17:34 -0800)]
Add option to automatically handle unsorted variable-length sequences in RNNs (#15225)

Summary:
Fixes #3584.

Motivation: manually sorting sequences, packing them, and then unsorting them
is something a lot of users have complained about doing, especially when we can
offer library support for them.

Overview: we internally sort sequences before packing them and store a list of
`unsorted_indices` that represent how to unsort the sequences inside
PackedSequence. The packing helper functions return PackedSequence with the
`permutation` field and the unpacking helper functions use it to unsort.

To implement this, the following changes were made:
- PackedSequence now keeps `sorted_indices` and `unsorted_indices`.
  These two can be thought of as permutations and are inverses of each other.
  `sorted_indices` is how the sequences were sorted; `unsorted_indices` is how
  to unsort the sequences.
- Added an `enforce_sorted` argument to pack_sequence and pack_padded_sequence
  that maintains the legacy behavior of error-ing out on unsorted-sequences.
  When `enforce_sorted=True`, these functions maintain their ONNX exportability.
- pack_sequence(sequences, enforce_sorted) takes in unsorted sequences.
- pack_padded_sequence can take in a padded tensor that represents padded,
  unsorted sequences.
- pad_packed_sequence unsorts the PackedSequence such that it is still the
  inverse operation of packed_padded_sequence.
- RNNs apply `sort_indices` to their input hidden state and apply
  `unsort_indices` to their output hidden state. This is to ensure that the
  hidden state batches correspond to the user's ordering of input sequences.

NOT BC-Breaking
- The default for pack_sequence and pack_padded_sequence is
  `enforce_sorted=True` to avoid breaking ONNX export. To use the new
  functionality, pass in `enforce_sorted=False`

Testing Plan
- Modified TestNN.test_pack_sequence, TestNN.test_packed_padded_sequence,
  and TestNN.test_variable_sequence (RNN test) to check the behavior
  of unsorted sequences, sorted sequences, and sorted sequences with
  enforce_sorted=True
- test/test_jit.py has a test to see if RNNs are exportable with
  enforce_sorted=True

5 years agoSupport enough of closures to write autograd functions (#15411)
Zachary DeVito [Thu, 20 Dec 2018 22:26:06 +0000 (14:26 -0800)]
Support enough of closures to write autograd functions (#15411)

Summary:
This PR adds enough of the infra for supporting closures (inner script functions) in order to allow us to expression symbolic gradients using them. We do not actually ever run graphs that contain these closures. The symbolic_script infrastructure just extracts them out of the original forward graph and turns them into discrete forward/backward pairs. This cuts down on the type annotations necessary to write forward/backward pairs and aligns closely with the "differentiator" function approach to expression reverse-mode AD.

Example:

This code:
```
import torch

r = torch.jit.CompilationUnit(
'''
def mul_forward(self, other):
    def backward(grad_output):
        grad_self = (grad_output * other).sum_to_size(self.size())
        grad_other = (grad_output * self).sum_to_size(other.size())
        return grad_self, grad_other
    return self * other, backward
''')

print(r.module.code)
```

Will produce this graph (pretty printed for clarity):

```
def mul_forward(self,
    self: Tensor,
    other: Tensor) -> Tuple[Tensor, Tuple[None, Tuple[Tensor, Tensor]]]:
  backward = (self.__lambda, (other, self))
  return (torch.mul(self, other), backward)

def __lambda(self,
    context: Tuple[Tensor, Tensor],
    grad_output: Tensor) -> Tuple[Tensor, Tensor]:
  other, self, = context
  grad_self = torch.sum_to_size(torch.mul(grad_output, other), torch.size(self))
  grad_other = torch.sum_to_size(torch.mul(grad_output, self), torch.size(other))
  return (grad_self, grad_other)
```

symbolic_script will then do some modifications to remove the unsuppored prim::Function node, yielding:

```
def mul_forward(self,
    self: Tensor,
    other: Tensor) -> Tuple[Tensor, Tuple[None, Tuple[Tensor, Tensor]]]:
  return (torch.mul(self, other), (other, self))

def backward(self,
    context: Tuple[Tensor, Tensor],
    grad_output: Tensor) -> Tuple[Tensor, Tensor]:
  other, self, = context
  grad_self = torch.sum_to_size(torch.mul(grad_output, other), torch.size(self))
  grad_other = torch.sum_to_size(torch.mul(grad_output, self), torch.size(other))
  return (grad_self, grad_other)
```

Fixing ONNX export of logical ops to have correct output datatype (#15185)

Summary:
Currently PyTorch ONNX exporter exports the logical ops (`lt`, `gt`, `le`, `ge`, `eq`) with output type in corresponding ONNX ops as type `tensor(uint8)`. But ONNX spec allows for only `tensor(bool)`, which is why models that have these ops fail to load properly.

This issue is captured in https://github.com/pytorch/pytorch/issues/11339. Part of this issue, relating to the allowed input types, has been fixed in ONNX spec by houseroad. This PR fixes the other part pertaining to output type.

Directly calculate coordinates in the original tensor using column index in the result tensor. Every GPU thread takes care of a column (two numbers) in the output tensor.

The implementation detects and handles precision loss during calculating the square root of a `int64_t` variable, and supports tensors with up to `row * column = 2 ^ 59` numbers.

multi-dim standard deviation for CUDA. (#14990)

Summary:
This is the CUDA version of #14535 .
It refactors Reduce.cuh to allow more general classes of reductions to be performed -- we no longer assume that the temporary data returned during reduction is just one scalar, and instead allow an arbitrary accumulate type.
We also allow 64-bit indexing when necessary, since in general we will no longer be able to accumulate directly in the output. (In the cases when we can, we continue to split the tensors until they can be addressed with 32-bits, as before).
As an initial use-case, we implement `std` in multiple dimensions.

OutputTensorCopyFrom takes four arguments: index, a source Tensor, TensorOptions and whether we want to perform an async call.
We want to provide some default option for TensorOptions, (1). default device to context_.device() (2). default dtype to input.dtype(). User can also explicitly provide these options to override default values.

next diff will change the order of TensorOptions parameter so that user don't need to write down tensor options unless they want to override.

Refactor dataloader.py (#15331)

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`.

Rename potrs to cholesky_solve (#15334)

Summary:
Changelog:
- Renames `potrs` to `cholesky_solve` to remain consistent with Tensorflow and Scipy (not really, they call their function chol_solve)
- Default argument for upper in cholesky_solve is False. This will allow a seamless interface between `cholesky` and `cholesky_solve`, since the `upper` argument in both function are the same.
- Rename all tests
- Create a tentative alias for `cholesky_solve` under the name `potrs`, and add deprecated warning to not promote usage.

5 years agoOptional ScalarType support for native functions & JIT (#15154)
Tugrul Ates [Wed, 19 Dec 2018 18:40:48 +0000 (10:40 -0800)]
Optional ScalarType support for native functions & JIT (#15154)

Summary:
For #6593 and #9515

This completes the support for optional<ScalarType> in native, JIT and autograd.

Note: Mostly following the existing implementation for optional<Scalar> that was added in https://github.com/pytorch/pytorch/pull/12582.

This PR introduces a way to make functions accept an optional dtype and it will unblock #9515 by allowing the `dtype` param for type promotion interface:
```
func: name(inputs, *, ScalarType? dtype=None, Casting casting=same_kind)
```

An alternative approach could have been using `ScalarType::Undefined` for the same purpose but without optional, though it would have been a bit hacky.
```
func: name(inputs, *, ScalarType dtype=Undefined, Casting casting=same_kind)
```

Here's an example use of this in action: https://github.com/pytorch/pytorch/pull/15133/commits/971f69eac69101955ed90078b44dab975d37a4f7

There are already a bunch of native functions that were getting optional `dtype` through function overloading. https://github.com/pytorch/pytorch/pull/15133 is the attempt to migrate all of those. I will send those changes separately after this since some functions (e.g. sum) need quite a bit of change in the codebase. See the commits over there.

Summary:
This PR adds clang-format automation:
- It only checks on whitelisted files, so we can enable incrementally without noise
- There is a pre-commit hook provided that will do the same check, plus prompt users to apply the clang-format changes (no change is made without the user agreeing).
