@AlekseiNikiforovIBM AlekseiNikiforovIBM force-pushed the s390x_transform branch 2 times, most recently from f562877 to b5130e2 Compare December 6, 2023 10:56
I, L and F specifiers are actually endian-aware aliases.
I;16 is a little-endian type. For big-endian I;16B has to be used.

This change fixes multiple tests in test/test_transforms.py
on s390x, including test_2d_ndarray_to_pil_image.
This change fixes multiple tests
like MNISTTestCase::test_feature_types
in test/test_datasets.py

Please note, that currently there are no way to way to test those changes, but as long as it does not regress little-endian path, does not modify too many call-sites (if it becomes the case a better design+some sort of linter will be needed) and does not affect performance critical pass for LE systems
