Summary:
export - print a method with python_print
import - import a method with import_method
We want to ensure:
export(g) == export(import(export(g)))
That is after after exporting/importing once, the graph will stay exactly
the same. This is less strict that g == import(export(g)) which would
require us to maintain a lot more information about the structure of the
IR and about the names of debug symbols.
This PR addresses this with the following fixes:
* print out double-precision numbers with high enough precision such
that they always parse in the same way
* when creating loop-carried dependencies, sort them
by variable name, ensuring a consistent order
* parse nan correctly
* DCE: remove unused outputs of if statements, and loop-carried dependencies
in loops that are dead both after the loop and inside the body of the
loop.
* Do not set uniqueName for variables whose names are _[0-9]+, these
are probably rare in user code, and we need a way to communicate
that we do not care about a variable name when re-parsing the graph.
Otherwise temporary variable names will jitter around.
* Expand the definition of a constant in printing code to None,
and family.
* Allow re-treeing to work as long as the only thing in its way is a
constant node. These do not have side effects but are sometimes
inserted in a different order when tracing compared to how we print them.
* Print all constant nodes out first in the order in which they are used_val
(or, if they are inlined, ensure they get assigned CONSTANT.cX number
in a consistent order). Cleanup tuples (this is done in the compiler,
but not in the tracer, leading to some tuple indexing jitter if not
done).
* use strtod_l, not std::stod which can throw exceptions
Other:
* Add REL_WITH_DEB_INFO to setup.py. It already existed for the
cmake files. Threading it into setup.py allows us to turn on
debug symbols with optimization everywhere.
* enable round trip testing for all generated graphs. This only adds
~6 seconds to total build time but tests printing for every graph.

PyTorch/Caffe2 on ROCm passed tests: https://github.com/ROCmSoftwarePlatform/pytorch/pull/280
For attention: bddppq ezyang
Docker rebuild for Ubuntu not urgent (getting rid of Thrust checkout and package install is mainly cosmetic). If docker for CentOS 7.5 is wanted, build is necessary. Build of PyTorch tested by me in CentOS docker. PyTorch unit tests work mostly, however, a test in test_jit causes a python recursion error that seems to be due to the python2 on CentOS as we haven't ever seen this on Ubuntu - hence please do not enable unit tests.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/13342
This PR introduces a few new concepts:
- DeviceGuardImplInterface, and implementations for CPU and CUDA, which
provide a generic interface for interfacing with device and stream state,
without requiring a direct dependency on the code in question.
- InlineDeviceGuard, a general template for generating both specialized
and dynamically dispatched device guard implementations. Dynamic
dispatch is done by specializing it on a VirtualGuardImpl.
- Provide a device-independent DeviceGuard class, which can be used even
from CPU code. It uses the aforementioned dynamic dispatch.
- CUDA-specialized CUDAGuard class, which doesn't have a dynamic dispatch
but can only be used from CUDA.
- StreamGuard, which is the same as above, but for streams rather than
devices.
- Optional variants of all the aforementioned guards, which are a no-op if
no device/stream is specified
- CUDAMultiStreamGuard, specifically for the case when we want to set
a device on every guard.
There are some subtle semantic changes, which have been thoroughly documented
in the class definition.
BC-breaking changes:
- Move constructor/assignment have been removed from all device guard
implementations.
- In some cases where you previously wrote 'set_device' (or 'set_stream'), you now must write
'reset_device', because if you switch devices/device types, the stream/device on the
previous device is unset. This is different from previous behavior.
- CUDAGuard no longer handles streams, or multiple streams. Use CUDAStreamGuard
or CUDAMultiStreamGuard as appropriate for your use case.

Summary:
libcaffe2.so depends on libgloo.a for the ops in caffe2/contrib/gloo.
Symbols in libgloo.a that are not used are ignored and don't end up in
libcaffe2.so. libc10d.a depends on the caffe2 target, which in turn
depends on the gloo target, and it expects all libgloo.a symbols to be
part of libcaffe2.so. Symbols from libgloo.a that are not used in
libcaffe2.so remain undefined in libc10d.a.
To fix this, we link to libgloo.a when linking _C.so, such that any
gloo symbols in libc10d.a are resolved when linking _C.so.

Summary:
This PR implements a DataLoader API for the C++ frontend.
The components present in this API largely match the Python API. It consists of:
- `Dataset`s: Conceptually a function from a set of indices to a batch of examples;
- `Transform`s: A functional transformation of a dataset. A `Map<D, T>` for Dataset `D` and transform `T` is itself a dataset;
- `Sampler`s: Specify a strategy for generating indices for a new batch;
- A `DataLoader`, with the ability to automatically parallelize fetching of samples across multiple worker threads;
Note that collation functions fall naturally out of the `Map<Dataset, Transform>` abstraction.
Things that are missing right now that maybe should be added:
- Memory pinning for CUDA tensors
The API was designed to be generalizable to almost any kind of dataset, transform or sampling strategy, while providing a convenient API out of the box. To achieve this, it is quite heavily templatized on various possible input types.
There are many parts to this PR! Right now, I would like feedback on:
- Your impression of the general usability of the API;
- Your impression of which parts seem too complex or overthought;
- The implementation of the parallelization aspects of the DataLoader. I've followed the Python implementation in some matters, but also differ in others. I think my implementation is a little cleaner and decouples components slightly better than the Python dataloader.
I haven't added too many comments yet, as this is fresh out of the oven. Let me know if anything is unclear from the code itself.
There also aren't any tests yet. I will write a comprehensive test suite once we agree on the API and implementation.

- need to unify the macros. See c10/util/Exception.h
This is mainly a codemod and not causing functional changes. If you find your job failing and trace back to this diff, usually it can be fixed by the following approaches:
(1) add //caffe2/c10:c10 to your dependency (or transitive dependency).
(2) change objects such as at::Error, at::Optional to the c10 namespace.
(3) change functions to the c10 namespace. Especially, caffe2::MakeString is not overridden by the unified c10::str function. Nothing else changes.
Please kindly consider not reverting this diff - it involves multiple rounds of rebasing and the fix is usually simple. Contact jiayq@ or AI Platform Dev for details.

Summary:
Currently the C++ API and C++ extensions are effectively two different, entirely orthogonal code paths. This PR unifies the C++ API with the C++ extension API by adding an element of Python binding support to the C++ API. This means the `torch/torch.h` included by C++ extensions, which currently routes to `torch/csrc/torch.h`, can now be rerouted to `torch/csrc/api/include/torch/torch.h` -- i.e. the main C++ API header. This header then includes Python binding support conditioned on a define (`TORCH_WITH_PYTHON_BINDINGS`), *which is only passed when building a C++ extension*.
Currently stacked on top of https://github.com/pytorch/pytorch/pull/11498
Why is this useful?
1. One less codepath. In particular, there has been trouble again and again due to the two `torch/torch.h` header files and ambiguity when both ended up in the include path. This is now fixed.
2. I have found that it is quite common to want to bind a C++ API module back into Python. This could be for simple experimentation, or to have your training loop in Python but your models in C++. This PR makes this easier by adding pybind11 support to the C++ API.
3. The C++ extension API simply becomes richer by gaining access to the C++ API headers.

Summary:
Python never closes shared library it `dlopen`s. This means that calling `load` or `load_inline` (i.e. building a JIT C++ extension) with the same C++ extension name twice in the same Python process will never re-load the library, even if the compiled source code and the underlying shared library have changed. The only way to circumvent this is to create a new library and load it under a new module name.
I fix this, of course, by introducing a layer of indirection. Loading a JIT C++ extension now goes through an `ExtensionVersioner`, which hashes the contents of the source files as well as build flags, and if this hash changed, bumps an internal version stored for each module name. A bump in the version will result in the ninja file being edited and a new shared library and effectively a new C++ extension to be compiled. For this the version name is appended as `_v<version>` to the extension name for all versions greater zero.
One caveat is that if you were to update your code many times and always re-load it in the same process, you may end up with quite a lot of shared library objects in your extension's folder under `/tmp`. I imagine this isn't too bad, since extensions are typically small and there isn't really a good way for us to garbage collect old libraries, since we don't know what still has handles to them.
