Change arg dtype from float to double in LPPool and nn/utils/clip_grad.h (#29584) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/29584 In Python, `float` dtype is always 64-bit (https://stackoverflow.com/a/8216110), and the C++ equivalent APIs should take `double` dtype to match the bit length.
