Hey @David_Reiss so I moved from Windows to Linux for this quantization.
As I  know BatchNormalization support is still not there so we have to fuse the BatchNormalization layer.
I tried to fuse the Batchnormalization layer with Convolution layer but it is not happening nor throwing any error.
After I am doing jit trace it is throwing same error which means BatchNormalization need to be fused
