This PR addresses a RuntimeError that occurs when loading W8A8 quantized Qwen2.5-VL models.
Changes:
_init_weights
inQwen2_5_VLPreTrainedModel
to safely skip non-floating tensors (e.g., int8 quantized weights) during initialization.normal_()
on integer dtypes.Note: This PR does not include the tester file
test_init_weights_safe.py
; that file exists only in the fork for private testing.
