in the paste here (https://github.com/raghavgurbaxani/Quantization_Experiments/blob/master/quantized_model.txt 5), the model doesn’t look quantized.  One would expect to see QuantizedConv instead of Conv and QuantizedLinear instead of Linear.  One thing to try could be to make sure to run the convert script and ensure that you see the quantized module equivalents afterwards.
