[quant][graphmode][fx] Standalone module support {input/output}_quantized_idxs (#49754)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49754
This PR adds the support for {input/output}_quantized_idxs for standalone module.
if input_quantized_idxs = [] and output_quantized_idxs = [], the standalone module will be expecting float
input and produce float output, and will quantize the input and dequantize output internally
if input_quantized_idxs = [0] and otuput_qiuantized_idxs = [0], the standalone module will be expecting quantized
input and produce quantized output, the input will be quantized in the parent module, and output will be dequantized
in the parent module as well, this is similar to current quantized modules like nn.quantized.Conv2d
For more details, please see the test case
