The lowering pattern for `aten.T` uses transposition implemented via
`linalg.generic`. For downstream passes it is advantageous to use named
ops wherever possible, so this patch changes the lowering to use
`linalg.transpose` instead.
Addresses an issue in <https://github.com/llvm/torch-mlir/issues/3651>
where some unflatten ops generated from onnx models weren't propagating
static shape information. It may be necessary to add further
optimizations for the more general case when some static information is
present in the unflatten (or possibly reshape/view) op's `sizes` list,
but not reflected in the output shape. These ops will only successfully
infer shapes if the `sizes` list is gotten from a list of constant ints
(with possibly one -1). A common example where this fails is when some
of the `sizes` are determined from `aten.size.int` ops on dynamic
tensors, and other `sizes` are known statically.
This PR includes:
- a canonicalizer for `aten.unflatten.int` which converts to
`aten.unsqueeze` when it is expanding one dim to two, and one of the new
dims is statically 1.
- an improvement to the folder for `aten.__or__.bool` which does not
rely on *both* operands being static.
Downstream projects don't necessarily register this C++ module. This
package removes the dependency and uses `torch.iinfo` to access the max
and min values instead.
This PR add `floordiv` to the `PY_BUILTIN_TO_TORCH_OP`. For
`aten.mul.int` and `aten.floordiv.int` ops, we add new Canonicalization
Patterns as follow:
```
%1 = torch.aten.mul.int %input, %const-5
%2 = torch.aten.mul.int %1, %const-6
```
Will be replaced by
`torch.aten.mul.int %input, %const-30`
And
```
%1 = torch.aten.mul.int %input, %const-5
%2 = torch.aten.floordiv.int %1, %const-5
```
Will directly return `%input`
This PR also relaxes the `float` type constraint in TorchToTosa for the
`AtenRsubScalarOp` conversion.
To test:
`cmake --build build --target check-torch-mlir-all`
This patch add a test for 638ef14, which use `linalg.broadcast` instead
of `generic` for convolution bias.

Supports the result with dynamic shape and scalar indices like
```
func.func @test_gather_scalar(%arg0: !torch.vtensor<[3,4,5],f32>, %arg1: !torch.vtensor<[], si64>) -> !torch.vtensor<[?,?],f32> attributes {torch.onnx_meta.opset_version = 13 : si64} {
%0 = torch.operator "onnx.Gather"(%arg0, %arg1) {torch.onnx.axis = 0 : si64} : (!torch.vtensor<[3,4,5],f32>, !torch.vtensor<[], si64>) -> !torch.vtensor<[?,?],f32>
return %0 : !torch.vtensor<[?,?],f32>
}
```
`Torch::AtenSqueezeOp` is referring to the result shape, so it will
failed on lowering if the result shape is dynamic.
The current implementation uses a `linalg.generic` to broadcast the bias
tensor for the lowering of convolutions. This is suboptimal for later
pattern matching. This patch changes it to use the respective named op,
`linalg.broadcast`, instead.
New sympy type is introduced to represent integer infinity in upstream
PyTorch repo. Subsequently, sympy.oo is no longer used to represent
infinity upper bound for dynamic dimensions where the upper bound is
unknown. Instead `int_oo` is used to represent integer infinity. This
commit updates the `_sympy_int_to_int` utility in light of this change.
The `axis` attribute is optionally available. Added support by computing
the pad based on the axis values.

MelWeightMatrix which lowers all the way to linalg.

better numpy impl 🙏

Without `--no-build-isolation` pip invokes `setup.py` in fresh
environment, which doesn't have `torch` installed. But `setup.py` does
`import torch` to check PyTorch version, so the build crashes. At the
same time the script creates a disposable virtual environment with all
required dependencies specifically to run wheel build. Note that Linux
package build also runs with this option.

This was introduced by this commit:
74f7a0c9d6
And looks like macOS builds were not running in CI ever since.
I also updated Python versions in `install_macos_deps.sh`.
Previously we only had full suite timeouts, making it impossible to
identify
which specific tests were hanging. This patch adds:
1. Per-test timeout support in the test framework
2. A default 600s timeout for all tests
3. A deliberately slow test to verify the timeout mechanism works
The timeout is implemented using Python's signal module. Tests that
exceed
their timeout are marked as failures with an appropriate error message.
This should help catch and isolate problematic tests that enter infinite
loops, without needing to re-run the entire suite multiple times.
Now that the PyDev feature request pytorch/pytorch#117188 has been
completed, we can remove all the ad-hoc code that propagates sparsity
metadata and replace it with the built-int PyDev metadata for sparse
tensors. This removes a lot of code and also ensures sparsity is
consistent with the torch.sparse package for all cases.
Set PyTorch and TorchVision version to nightly release 2024-08-18.
This commit also updates the `scaled_dot_product_attention` op.
A new attribute `enable_gqa` has been added. As of now, only the
default value for the same is supported.

Current pip installation command raises error
```
ERROR: Could not find a version that satisfies the requirement torch-mlir (from versions: none)
ERROR: No matching distribution found for torch-mlir
```
(checked on Ubuntu 22.04.2 LTS with `venv` and with `conda`)
Because it is trying to install torch-mlir from pytorch repository. The
installation command was wrongly split into 2 in #3073. I just merged
them back to 1 installation command with both pytorch and
llvm/torch-mlir channels.

Most likely when building with stablehlo, while waiting for it missing

The `layout` attribute was not considered for the `onnx.RNN` operation.
Added support for the attribute to transpose the inputs / outputs of the
RNN when valid.
The einsum lowering was missing the behavior for duplicate indices in
the equation. This amounts to a diagonalization along duplicate pairs of
indices in the equation.
Closes#3575
The PyTorch remainder operator is meant to compute the Python modulus
operator entrywise:
https://pytorch.org/docs/stable/generated/torch.remainder.html#torch.remainder
In python the modulus operator is meant to always return a result with
the same sign as the divisor:
https://docs.python.org/3/reference/expressions.html#binary-arithmetic-operations
In other words, torch.aten.remainder should return a Python-style
modulus instead of a C-style modulus. However the remainder operator was
simply translated into arith.ModSI or arith.ModF, which both effectively
compute the C-style modulus. Now the lowering has been modified so that
the modulus operator works properly with negative numbers, both in the
dividend, and the divisor.
