Pull Request Overview

This PR adds validation for the chunks parameter in paddle.chunk and corresponding error-case tests.

• Enforces that chunks must be >0 and ≤ the size of the specified (non-negative) axis.
• Raises ValueError when chunks is out of range.
• Adds unit tests for negative and too-large chunks values.

File	Description
test/legacy_test/test_chunk_op.py	Added tests for chunks=-1 and chunks>dim to ensure errors.
python/paddle/tensor/manipulation.py	Inserted a guard to validate chunks bounds and raise ValueError.

test/legacy_test/test_chunk_op.py:63

• Add a test case for a negative axis (e.g., axis=-1) with chunks larger than that dimension to verify the validation logic for negative axes.

            def test_negative_chunks_tensor():

python/paddle/tensor/manipulation.py:4487

• The current check only covers non-negative axes. Negative axis values (e.g., -1) bypass this validation and may lead to inconsistent behavior; consider normalizing negative axes before comparing against x.shape.

        isinstance(axis, int) and axis >= 0 and chunks > x.shape[axis]

Minor spelling issue: change 'meanless' to 'meaningless' in the comment.

Suggested change

	# check the chunks value to avoid the meanless split operation, such as <=0 or > x.shape[axis]
	# check the chunks value to avoid the meaningless split operation, such as <=0 or > x.shape[axis]
