Static quantization tutorial missing a step

Line 514 in 7bd0315

per_channel_quantized_model.qconfig = torch.quantization.get_default_qconfig('fbgemm')

If I understand correctly, one needs to also set
torch.backends.quantized.engine = "fbgemm"

I tried to quantize a model without the missing step and got strange errors about certain operations not being supported on the FBGEMM backend. They go away with this step added.
