This commit sets the PyTorch and TorchVision version to nightly release
2024-11-07.
This commit also updates the dtype check for the
`aten.fake_quantize_per_tensor_affine` and
`aten.fake_quantize_per_tensor_affine_cachemask` op since the op now
supports bfloat16 input.

For the op `index_put_`, if accumulate == false, the behavior is
undefined if the indicies aren't unique
(https://pytorch.org/docs/stable/generated/torch.Tensor.index_put_.html).
So, when converting `AtenIndexPutHackedTwinOp` to a TMTensor scatter op,
mark the indices as unique if when `accumulate == false`.
This should have no functional effect (unless users are relying on UB)
and assuming unique indices has the benefit of unlocking better
optimizations in further compiler stages.

In torch.index_put like ops, `values` is only required to be
broadcastable to `input[indices]`, rather than exact dimension match.
This patch fixes the problem by add additional
stablehlo.dynamic_broadcast_in_dim before creating stablehlo.scatter op.
BTW, this patch also enhance the `getBroadcastResultShape` utility in
hlo namespace.

1. Clamps OOB start index to 0 in slice folder
2. Adds a more descriptive `emitError` in slice folder if the creation
of the `DenseElementsAttr` would fail due to a bad result shape.
3. Fixes the `onnx.Shape` lowering to default to `inputRank` for `end`
instead of `-1`. When `end==-1` the last element was missing when
slicing.
1. Adds case handling for `aten.slice.tensor` shape inference with
negative strides. This is not technically allowed by native pytorch, but
it is useful for ONNX ingest. We were getting some incorrect shapes for
these negative strided slice ops.
2. Adds scalarization support for ops seen in pytorch pad exports to
ONNX. These are typically `aten.view` `aten.transpose.int` and
`aten.slice.Tensor` with negative strides (and rank 2).
3. Allows view op `self` to be added to the worklist conditionally,
based on whether the view op actually occurs as a middle point in a
shape computation.
The onnx ingest sometimes has poorly propagated shape information. E.g.:
```mlir
...
%9020 = torch.prims.squeeze %9010#1, %9019 : !torch.vtensor<[?,384,1],f32>, !torch.list<int> -> !torch.vtensor<[1,384],f32>
return %9015, %9020 : !torch.vtensor<[1,384],f32>, !torch.vtensor<[1,384],f32>
}
}
```
This occurred at the boundary of the onnx model
`migraphx_bert__bert-large-uncased`. Evidently, the output value tensor
info had more information than could be propagated forward. The
`PrimsSqueeze` lowering was returning a `!torch.vtensor<[?,384],f32>`
which was causing a type mismatch with the `func.return`.
Added lit tests since these scalar operations don't trace well through
the `fx_importer` route.
`XOR` and `NE` are equivalent binary operators, so `aten.ne.bool` is
lowered to `arith.xori`.
The existing TorchToTosa lowering logic for `torch.aten.avg_pool2d`
doesn't handle some unsupported properties well, leading to a silent
wrong answer(SWA) when we go through
`torch-backend-to-tosa-backend-pipeline.` For instance, with the
existing TOSA avgpool2d specification, we can not represent
`count_include_pad` and `divisor_override,` so during TorchToTosa
lowering, we silently ignore these properties which leads to SWA in some
cases—the fix captured in this change errors for unsupported scenarios.
For details on `count_include_pad` and `divisor_override,` please see
the below link.

[TorchToLinalg Op
Support](https://github.com/nod-ai/SHARK-ModelDev/issues/347)
# Description
Aten_TrilinearOp is an implementation of a "trilinear einstein sum".
Essentially, just an einsum across 3 tensors.
There are a few inputs:
## Tensor Inputs
- i1, i2, i3 - The three input tensors for the _trilinear op.
## Expands
These inputs allow you to unsqueeze an input tensor at the specified
dims as a pre-processing step to make the shapes compatible for the rest
of the op:
- expand1: List[int], expand2: List[int], expand3: List[int]
## sumdim
- sumdim: List[int] - After applying element wise multiplication, the
values in sumdim denote where to collapse a dimension by summing over it
## unroll_dim
- unroll_dim: int - In the PyTorch implementation, this specifies a
dimension where you could slice the input tensors, multiply and sum
them, then concatenate the results in an output tensor. This complicates
the implementation significantly, but doesn't change the result, so I
opted against it. Along with that, a previously accepted path for
solving this involved reusing the AtenEinsumOp, which also would also
ignore this input.
# Solution
After trying a bunch of more complicated approaches for it, this op
actually ended up being quite simple: [See
_trilinear](https://dev-discuss.pytorch.org/t/defining-the-core-aten-opset/1464)
`_trilinear = (i1.unsqueeze(expand1) * i2.unsqueeze(expand2) *
i3.unsqueeze(expand3)).sum(sumdim)`
Wish I saw this earlier, but watcha gonna do: 🙃
## Not Reusing AtenEinsumOp
Frankly, I found multiple cases where valid inputs would have numerical
mismatches for EinsumOp, even when running tests against EinsumOp
directly. I think it has something to do with the singleton dimensions.
Will need to look into this further, but once I realized the simplified
approach, it appeared to be more reliable and much simpler.
Either way (credit to @zjgarvey), there are improvements to the einsum
op here. When I was originally trying to use the op, intermediate
tensors were being flattened properly, but then its 0th dimension was
being cast from a static dim to a dynamic dim due to integers not
folding correctly in the MLIR. Figured it's worth keeping these
improvements for future reusers of EinsumOp.
# The zero'd out dim "bug"
For some reason, if you specify a dimension in all `expands`,
```i.e.
[expand1=[0], expand2=[0], expand3=[0]],
[expand1=[1], expand2=[1], expand3=[1]]
```
The _trilinear op would specify `0` for that dimension in the output
shape, unless it was also included in `sumdim`. This goes against the
implementation of torch.einsum:
```
>>> a, b, c = [torch.rand(1, 3, 3, 3) for i in range(3)] # Simulate expand at dim=0 for all input tensors
>>> torch.einsum('abcd,abcd,abcd->abcd', a, b, c).shape
torch.Size([1, 3, 3, 3])
```
And is just straight up incorrect mathematically. I considered
"replacing" singleton dims with zeroed out dims, but that seemed like
carrying over a bug. Instead, I included a test for the case, verified
that the singleton dimensions were handled the way that torch.einsum
handles it, instead of torch._trilinear, and xfailed it with a note as
to why.
A non-persistent buffer will not be a part of this module’s
`state_dict`. Hence when setting `experimental_support_mutation=True`
and have non-persistent buffer, the current fx importer will fail to
retrieve a value from `state_dict` and produce `torch.constant.none` to
represent the buffer. This fix get value of non-persistent buffer from
the module's `constants`.

This commit sets the PyTorch and TorchVision version to nightly release
2024-10-29.
This commit also fixes the CI failure after this commit
54d9e24013
got merged. The issue was that the CI checks in the PR were run before
the previous roll pytorch update but the PR was actually merged after
the roll pytorch update. Hence, the failure was not caught before
merging the PR.
While exporting the fx_graph through fx_importer for `rrelu` and
`rrelu_with_noise` op for train mode, it decomposes the
`aten.rrelu_with_noise` op based on the PyTorch decomposition which is
the default behavior. However, the decomposition contains an input
mutation specifically here
9bbe4a67ad/torch/_decomp/decompositions.py (L325),
resulting in the runtime failure. This issue would probably be fixed by
https://github.com/pytorch/pytorch/pull/138503. Until then, the failing
tests are added to the xfail set.
Also, after the roll pytorch update following tests started passing for
fx_importer, and fx_importer_stablehlo config.
- "ElementwiseRreluTrainModule_basic"
- "ElementwiseRreluTrainStaticModule_basic"
- "ElementwiseRreluWithNoiseTrainModule_basic"
- "ElementwiseRreluWithNoiseTrainStaticModule_basic"
This commit also updates the dtype check for the `aten.linear` op since
the op now expects both the input tensors to have the same dtype.

1. Negative indices for tensor indexing is handled by wrapping around
the index values by checking their values at run time. Without the fix,
there was a runtime error.
2. Added a lit test to lock down the behavior.
3. Updated the `xfails_set` for `fx_importer_tosa` config to lockdown

Reports a match failure for the pattern `FullyUnrollPrimLoop` when the
loop op is not in a region defined by a `torch.shape.calculate` op.
This is needed to avoid unrolling prim loops generated by ONNX IR, since
we are applying shape refinement in the
`torch-onnx-to-torch-backend-pipeline` introduced in fa4794d .
See also the discussion in
<https://github.com/iree-org/iree/pull/18867#discussion_r1811101655>
I've upstreamed the necessary quantized linalg Op with the
"channel-first" ordering used by torch
(https://github.com/llvm/llvm-project/pull/107740) for 2d convolution.
This patch changes the lowering for the quantized 2d case of
`aten.convolution` accordingly, which saves three transpositions per
convolution (input, weights, result) and therefore removes the
requirement to try to optimize these away in downstream passes.
The fx tracer does not support tracing "real" quantized tensors
currently. A "real" quantized tensor here means a tensor that is created
using a method like `torch.quantize_per_tensor()` and carries the
quantization parameters (scale, zero_point, scheme) in the object.
However, it seems like the DQ-Q type fake quantizatation is now commonly
used as a high level representation of quantized operators and is only
lowered to native quantized ops (if available) in the respective
hardware backend. Quantization of floating point modules in PyTorch is
recently also performed as a graph transformation after
exporting/tracing the original module.
```python
# Examples of "real"/native quantization
tens = torch.randint(-127, 127, (1,), dtype=torch.int8)
torch._make_per_tensor_quantized_tensor(tens, 1, 0)
# tensor([90.], size=(1,), dtype=torch.qint8,
# quantization_scheme=torch.per_tensor_affine, scale=1.0, zero_point=0)
tens = torch.rand((1,))
torch.quantize_per_tensor(tens, 1, 0, torch.qint8)
# tensor([1.], size=(1,), dtype=torch.qint8,
# quantization_scheme=torch.per_tensor_affine, scale=1.0, zero_point=0)
# Example of DQ/Q quantization
import torch.ao.quantization.fx._decomposed
tens = torch.rand((1,))
torch.ops.quantized_decomposed.quantize_per_tensor.default(tens, 1, 0, -128, 127, torch.int8)
# tensor([1], dtype=torch.int8)
```
This means that a typical import flow for a quantized network
into/through torch-mlir would look like this:
`torch.export() -> quantization transformations on fx graph ->
fx_importer` Where the tensors in the graph are normal float/int tensors
and the quantization parameters are carried by the DQ/Q ops. These kinds
of graphs can be traced without issues.
Currently, our quantized convolution tests use the "real" quantized
tensors. This means that with the retirement of the `jit_ir_importer`,
these tests cannot be imported any longer. In summary, I see no reason
to stick to the "real" quantization in these tests, as both PyTorch 2.0
is using DQ/Q quantization and our linalg backend is also using it.
This patch updates our quantized convolution tests to use the DQ-Q
quantization with the ops from `torch.ops.quantized_decomposed`.
Note: For future reference, there seems to be an ongoing consolidation
of the ops for the DQ/Q scheme on the PyTorch side
(https://github.com/pytorch/ao/issues/986#issuecomment-2390296826).
### new patterns:
1. Propagates `aten.broadcast_to` ops of a single value to an
`aten.full` op
2. Propagates arithmetic operations through a templated class which
associates some tensor arithmetic ops to their integer-scalar
counterparts. These are a major blocker right now, since some models
have a bunch of rank 0 arithmetic being done with tensor ops. See the
lit test for an interesting example that pads an input to the smallest
shape which will become divisible by twelve in `dim0`. If you think this
is convoluted, you haven't been staring at ONNX generated IR long
enough.
3. Adds a stronger folder for `aten.eq.int` to fold `size.int == 0` to
`false`. See the comment in that conversion pattern for more
justification as to why it is acceptable to make this assumption here.
This is another major blocker for models, since this lack of folding
propagates to lack of folding for subsequent `where.self` operations.
4. Add `AtenSqueezeDim` to the existing `FoldAtenSqueezeOpPattern`
### other changes:
1. Add two new anchor ops: `AtenArangeStartStepOp` and
`Torch::RuntimeAssertOp`. I've checked all possible sources of the
runtime assert ops and it is always shape related. The Arange op only
takes int inputs, and these are all shape related. Adds a size check to
getting a list from literal ops.
2. Improved folders for int arithmetic ops to fold some common patterns.
3. adds the ability to get some values from scalar-tensor ops to
getListFromTensor.
4. further cleans up getListFromTensor for readability.
### points to scrutinize:
1. I made the choice to scalarize `div.Tensor` (int dtype result) to
`floordiv.int`. This is because our shape computations involving this
kind of arithmetic are never negative in practice, and we don't have a
"round towards zero" scalar int divide counterpart.
2. Anchoring on `RuntimeAssertOp` sounds really suspicious, and if
someone happens to add a runtime assert in the future that doesn't boil
down to shapes, then it would add to the worklist considerably. We might
be able to get around this by adding "NoMemoryEffect" to ops which are
"ReadOnly" so that the inputs for the runtime asserts get cse'd with
existing elements of the worklist before we even get to this pass.
This is a first step towards reworking the scalarize-shapes pass which
has been integral to our ONNX frontend path detangling shape
computations.
## Purpose:
1. Restrict the scope of the pass to only apply to op sequences which
are used to compute shapes.
2. Make the pass more efficient by applying patterns in an appropriate
order for scalarization propagation.
3. Report failed scalarization patterns for easier debugging (Not yet
implemented). I can't seem to find a good path for this right now to
capture the right diagnostics. I'd like to defer this addition to a
later patch so we can add some high-value patterns to this pass in the
meantime.
With these changes, some reworking of the conversions themselves will be
necessary.
1. The removal of the SqueezeDim fold pattern was an appropriate fix to
avoid folding a pattern that may be needed to propagate further. The
reversal of pattern application order uncovered this bug. The addition
of rank 0 item logic was added to replace the functionality needed from
the squeeze dim pattern.
2. Rework getListFromTensor to modify a `SmallVector<OpFoldResult>` to
allow processing value tensor literals without immediately materializing
the ints. This should factor out a significant portion of code that was
used in specific cases to handle constants.
## RFC 1:
Currently, we are going to add all prim list of int ops to the worklist.
Can anyone identify problems with uniformly anchoring on prim lists of
ints? E.g. Does there exist a Torch Op satisfying all of the following
conditions:
1. Accepts a list of constant ints, LIST, as an input
2. The role of LIST is **not** shape related. All the examples I can
think of are indeed shape related: padding ints passed to a pad op,
kernel size ints passed to a conv op, size ints passed to a view op,
etc.
4. The LIST is not gotten entirely from scalars already.
If there does not exist a torch op satisfying all three of those
conditions, I think it will be safe to "anchor" on prim lists of ints.
### Conclusion for RFC 1:
I just scanned through the `GeneratedTorchOps.td` and `TorchOps.td` for
all references of `AnyTorchListOfTorchIntType` and verified this will
not be problematic to apply in any of those cases.
## RFC 2:
What should I use to report failed scalarization?
Like my dumb idea was just to walk back through the func op after
applying the passes and check if anything in the worklist is still a
tensor. If so, emit/log a warning. It certainly works, since you can
just look at the warnings and start debugging from the last printed
warning upwards, but there has to be a better way to handle this without
walking back through the func.func op.
### Conclusion for RFC 2:
I tried a few things without much success. The fundamental problem is
that identifying the cause of a failed scalarization could be myriad:
1. We could be missing a pattern for an op entirely: E.g., a pattern we
need is scalarizing rank0 arithmetic ops (e.g. AtenMulTensorOp ->
AtenMulIntOp).
2. We could fail a scalarization pattern because it should fold instead.
This is specifically the case for rank0 where.self ops. These ops MUST
fold, or we need to have custom lowering logic for the rank 0 case.
3. Walking through the func op a second time and emiting a warning for
ops that have tensor result types seems to give locations that are
inconsistent or hard to track in the converted IR. Doing this on IR that
doesn't apply any patterns seems to give decent information, but it's
still dramatically insufficient considering how complex these patterns
can get, and still takes manually reading IR to try and figure out what
is really blocking the simplification.
I'd like to skip out on fleshing out the error reporting for now and
come back to it after iterating a few time on the patterns.
This commit adds the torch-onnx-to-torch-backend pipeline which
converts the Torch Onnx IR to Torch Backend IR.
This commit also moves the `ScalarizeShapes` pass from the
`torch-backend-to-linalg-on-tensors-backend-pipeline` to the
`torch-onnx-to-torch-backend` pipeline since the primary goal of
this pass is to scalarize the shapes in the IR coming from the
Onnx models.
I'm trying to build python wheel for windows similar to as done for

the build process on windows is broken without the following fixes:
1. Building stablehlo for windows fails due to

stablehlo in `build_windows_ci.sh` that will be used for building the
python wheels.
2. Add `USE_MATH_DEFINES` to resolve

Adds onnx ConvTranspose support for autopadding
(https://github.com/nod-ai/SHARK-ModelDev/issues/839).
- Adds support for attribute auto_pad="SAME_UPPER" or "SAME_LOWER" which
will automatically calculate padding of input based on output shape.
- Adds support, during auto-padding, for output_shape=[H,W] which
overrides the default output shape of input_shape[i]*stride[i] (for
spatial dimensions only).
- Adds lit test for auto-padding.
- Tests are added by https://github.com/nod-ai/SHARK-TestSuite/pull/370
NOTE: ConvTranspose still doesn't support asymmetric padding, therefore
multiple original onnx tests still won't pass.
