Add pad_left option to PadRagged for left-side padding support #1338

yfyeung · 2025-07-11T16:05:21Z

This PR adds a new boolean parameter pad_left (default: false) to the PadRagged function. When set to true, padding is applied to the left side of each sublist instead of the default right side.

Can you also add a test?

Please see k2/python/tests folder.

There are many test files.

I have added corresponding pad left tests for all existing pad right tests.
The make test results show that all tests passed except for Test.Cuda.cu_hash_test.

Pull Request Overview

This PR adds a pad_left boolean flag (default: false) to the PadRagged operation so users can choose left-side padding instead of the default right-side padding.

Extend the C++ PadRagged API and its Python bindings (pad method and pad_ragged function) with the pad_left parameter.
Implement left-side padding logic in the ragged_ops_inl.h template for both constant and replicate modes.
Update tests to cover pad_left=True for integer and floating‐point ragged tensors in constant and replicate modes.

k2/python/csrc/torch/v2/ragged_any.h	Updated `RaggedAny::Pad` signature to include `pad_left` parameter.
k2/python/csrc/torch/v2/ragged_any.cu	Passed `pad_left` through to `PadRagged` and updated the binding.
k2/python/csrc/torch/v2/any.cu	Added `pad_left` argument to the Pybind11 `.def("pad", ...)` call.
k2/python/csrc/torch/ragged_ops.cu	Extended the `pad_ragged` free function binding with `pad_left`.
k2/csrc/ragged_ops_inl.h	Implemented left‐padding code paths in `PadRagged` template.

k2/python/csrc/torch/v2/ragged_any.h:272

Update the documentation comment for Pad to include the new pad_left parameter, explaining its behavior and default value.

  /// Wrapper for k2::PadRagged

k2/python/csrc/torch/v2/any.cu:363

Ensure that the kRaggedAnyPadDoc docstring for pad is updated to describe the new pad_left argument and its default behavior.

          py::arg("pad_left") = false, kRaggedAnyPadDoc);

k2/python/tests/ragged_ops_test.py:183

Consider adding a test for the free function pad_ragged(src, mode, padding_value, pad_left=True) to verify the pad_left parameter in the standalone API binding.

[nitpick] Consider renaming the variable len to row_len (and extra to something like pad_len) to improve readability and avoid shadowing standard functions.

Suggested change

len = idx0x_next - idx0x,

extra = col_num - len;

if (pad_left) {

if (j < extra)

res_acc(i, j) = padding_value;

Can you add a test for an empty sublit list in the ragged tensor?

csukuangfj

Thanks! Left some minor comments. Otherwise, looks good to me.

Yes, do these two cover the case?
