When applying quantization supported by pytorch 1.3 to Resnet 50, the following error occurs.
RuntimeError: Didn’t find engine for operation quantized::linear_prepack NoQEngine (operator () at …\aten\src\ATen\native\quantized\cpu\qlinear_prepack.cpp:202)
(no backtrace available)
I installed pytorch 1.3 using anconda,
and there seems to be no environment for python setup. I think it need additional library(FBGMM) settings, do you know how?
I think FBGEMM should be turned for machines/compilers that support it by default, can you print torch.backends.quantized.supported_engines to see if fbgemm is there?
