Undefined behavior with memset of std::string to 0 (#18703)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/18703

 `zeroPtr` is sometimes a `std::string` tensor, so `memset` to 0 is undefined behavior.

This might be accidentally safe with `std::string` implementation that use SSO (Small String Optimization), but will crash otherwise.

Adding pin_memory kwarg to zeros, ones, empty, ... tensor constructors. (#18455)

Summary:
Make it possible to construct a pinned memory tensor without creating a storage first and without calling pin_memory() function. It is also faster, as copy operation is unnecessary.

Supported functions:
```python
torch.rand_like(t, pin_memory=True)
torch.randn_like(t, pin_memory=True)
torch.empty_like(t, pin_memory=True)
torch.full_like(t, 4, pin_memory=True)
torch.zeros_like(t, pin_memory=True)
torch.ones_like(t, pin_memory=True)
torch.tensor([10,11], pin_memory=True)
torch.randn(3, 5, pin_memory=True)
torch.rand(3, pin_memory=True)
torch.zeros(3, pin_memory=True)
torch.randperm(3, pin_memory=True)
torch.empty(6, pin_memory=True)
torch.ones(6, pin_memory=True)

Hi. It seems that when building CPP-extensions with CUDA for Windows, an `extra_cuda_cflags` options are not properly forwarded to `nvcc`.

Use of extra CUDA options is necessary to build, for instance, a InplaceABN (https://github.com/mapillary/inplace_abn), which requires `--expt-extended-lambda` option.

More type stubs (#18511)

* The `device` module
* The `cuda` module
* Parts of the `optim` module
* Began adding stubs for the `autograd` module. I'll annotate more later but `no_grad` and friends are probably the most used exports from it so it seemed like a good place to start.

This would close #16996, although comments on that issue reference other missing stubs so maybe it's worth keeping open as an umbrella issue.

The big remaining missing package is `nn`.

Also added a `py.typed` file so mypy will pick up on the type stubs. That closes #17639.

C++ handler for gradient reduction (#18251)

Summary:
This commit adds the `c10d::Reducer` class that hooks into autograd
and performs gradient bucketing and reduction. These are the core
parts of `nn.parallel.DistributedDataParallel` that up to now were
only usable for CUDA models.

This should enable the following:

* Distributed data parallelism for models defined using the C++ frontend.
* Allow overlap of gradient computation and reduction for non-CUDA models.
* Enable distributed data parallelism for models with some unused parameters.

This does not include any logic for computing bucket assignment, which
can be done separately; either by observing autograd execution order
(this is what Apex does), or by assigning buckets based on some
maximum byte size, or both.

Since we are going to add ideep to ATen, and ATen is always compiled, it makes sense to have the registration in ATen rather than C2.

Ailing Zhang [Sun, 31 Mar 2019 15:41:46 +0000 (08:41 -0700)]
Enforce check ad in test_jit (#18509)

Summary:
If a test triggers autodiff, it must have a `DifferentiableGraph` in its differentiated forward graph, and this subgraph must have either the original aten node, or the corresponding nodes used in AD formula.

Typically a forward differentiable graph looks like this:
```
graph(%i0 : Float(),
      %i1 : Float()):
  %3 : Float() = prim::DifferentiableGraph_0(%i0, %i1)
  return (%3)
with prim::DifferentiableGraph_0 = graph(%0 : Float(),
      %1 : Float()):
  %2 : Float() = aten::max(%0, %1)
  return (%2)
```
which tells us `aten::max(Tensor self, Tensor other) -> Tensor` is symbolically differentiable.

Update: there're a lot of cases (fusions/ConstantChunk/python implementations) that breaks it so I decided to make the check optionally take node names if different from function name.
~~[OLD]Theoretically I could also check if `aten::max` is in the differentiable block or not to be more precise, but there're also cases like `chunk` where in a differentiable block it's replaced with a prim node (ConstantChunk) and we will have to special case them. Any suggestions here (to be more precise or no) is very welcome!~~

We used to have a list containing nn tests should be run against AD, I moved it to an field when constructing our test(either torch or nn). I think it's cleaner this way, and it matches the fact that for the same op we support one schema of it but not all, in this way we could just turn on the corresponding test which triggers that supported schema.

[Done] :
- Going through a manual second pass of all tests to check if they should enable AD test or not....
- Add a readme about how to add AD for an op and how to add/enable its test in test_jit.

Fix wrap(at::Scalar) (#18632)

Summary:
Problem:
```cpp
// This function expects a `Variable` as input
inline PyObject* wrap(at::Tensor tensor) {
  return THPVariable_Wrap(Variable(std::move(tensor)));
}

inline PyObject* wrap(at::Scalar scalar) {
  // This function calls `wrap(at::Tensor tensor)` (the function above), but since
  // `scalar_to_tensor(...)` returns a `Tensor` and not a `Variable`, the call to
  // `wrap(at::Tensor tensor)` will fail with "Tensor that was converted to Variable
  // was not actually a Variable", which is not what we want.
  return wrap(scalar_to_tensor(scalar));
}
```

The right fix is to call `make_variable(...)` with the tensor returned from `scalar_to_tensor(scalar)`.

This unblocks https://github.com/pytorch/pytorch/pull/18230 as it is the only patch that hits this code path now. All other native functions that return Scalar (such as `item()` or `_local_scalar_dense()`) either has custom-defined implementation that doesn't go through this path, or is not exposed to Python at all.

My main goal was to clarify:
- Target sequences are sequences of class indices, excluding the blank index
- Lengths of `target` and `input` are needed for masking unequal length sequences, and do not necessarily = S, which is the length of the longest sequence in the batch.

I thought about Thomas's suggestion to link the distill.pub article, but I'm not sure about it. I think that should be up to y'all to decide.

New operator registration MVP (#18161)

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/18161

This introduces version 0 for the new operator registration.

For now, it only works with kernels that are defined as stack-based functions.
This is actually not the intended public API for defining kernels, but it's the basis which is going to be used to define the public APIs (see diffs on top for them),
and it's also the API used for exposing caffe2 operators.

This diff also switches the mechanism for exposing caffe2 operators to the new mechanism.

5 years agoExperimental logging/counters API (#18235)
James Reed [Sat, 30 Mar 2019 00:06:08 +0000 (17:06 -0700)]
Experimental logging/counters API (#18235)

Summary:
This defines a generic counters API that users can utilize to provide monitoring functionality in e.g. a production service. We expose both counters for runtime internals as well as a TorchScript API to create user-defined counters. Synopsis of the API:

- `torch/csrc/jit/script/logging.h` specifies the externally-facing API in C++
- `torch/jit/_logging.py` specifies the Python API

We use an interface, `LoggerBase`, to define the interactions between users and a logging backend. Implementing a subclass of `LoggerBase` allows the user to handle these events in a custom way, such as logging into a DB or calling into an infra-specific counters API.

From the frontend perspective, we can create log events in two ways:
1. We provide an `add_stat_value(name, val)` function. This calls into the Logger backend with a key/value pair. For example, we might call `add_stat_value('foo', 1)` to bump an event counter.
2. We provide a `time_point()` function to record a timestamp in nanoseconds. This can be used in conjunction with `add_stat_value` to record runtime wall clock durations.

Examples of frontend usage can be found in `test_jit.py TestLogging`.

We provide a trivial `LockingLogger` implementation as an example and for testing purposes. It is likely not ready for production usage. It demonstrates that a backend implementing the API can do things like specify aggregation types and report these aggregate stats via the `get_counters()` API.

Update argument names of torch::autograd::FunctionPostHook (#18140)

Summary:
They are called as (outputs, inputs) and were named (inputs, outputs).

Possible follow up fix is to make the outputs argument an lvalue to allow for calling multiple post hooks without ever copying outputs vector. It looks like the copy is now forced because the hook takes a const reference as input and returns an value. This would change the prototype of the function, so needs further discussion.

Rename `btrifact*` to `lu` (#18435)

Summary:
Changelog:

- Renames `btrifact` and `btrifact_with_info` to `lu`to remain consistent with other factorization methods (`qr` and `svd`).
- Now, we will only have one function and methods named `lu`, which performs `lu` decomposition. This function takes a get_infos kwarg, which when set to True includes a infos tensor in the tuple.
- Rename all tests, fix callsites
- Create a tentative alias for `lu` under the name `btrifact` and `btrifact_with_info`, and add a deprecation warning to not promote usage.
- Add the single batch version for `lu` so that users don't have to unsqueeze and squeeze for a single square matrix (see changes in determinant computation in `LinearAlgebra.cpp`)
