quantization previously didn’t work on windows because fbgemm wasn’t supported on windows. This is no longer the case so there should be no issue (Is this available on windows? · Issue #150 · pytorch/FBGEMM · GitHub 1). Additionally, the issue wasn’t that you couldn’t do quantization on windows, its that windows didn’t have kernels for quantized ops, so you could still do the quantization, you just couldn’t run the quantized model.
note: torchscript wouldn’t get around this, but it is a good solution to not wanting to go through the quantization process each time you want to load a quantized model.
