Xia, Weiwen b5bfbba184 [Quant][CPU] fix fake_quantize_per_tensor_affine of inf values (#155109) ... Fixes #154328 **Summary** Fail reason: The input value is infinity in float and it has undefined behavior to convert it to int64_t. On X86, it will be converted to the min value of int64_t, which is not expected. Fix: Clamping `(input * inv_scale + zero_point)` to `[quant_min, quant_max]` before converting it to int64_t. **Test plan** ``` pytest test/quantization/core/test_workflow_ops.py -k test_fake_quantize_per_tensor_affine_inf ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/155109 Approved by: https://github.com/leslie-fang-intel, https://github.com/jerryzh168		2025-06-26 01:24:36 +00:00
