Ceil also have gradient zero for which I can access it’s gradient using param.grad but in case of le it returns none.Should I assume that pytorch give none value for gradeint. Also I have found this       https://github.com/pytorch/pytorch/blob/7707dee76169a2c2d6637f80af5ed59eeb32a997/torch/csrc/jit/symbolic_script.cpp#L825 5 .
What’s your call on this?
