The above exception was the direct cause of the following exception:

eager_fail_to_run

Reproduce the failure with the provided benchmarks/dynamo/torchbench.py command and inspect forward_and_backward_pass in that file. Then trace the Float/Half mismatch through torch/ao/quantization/fake_quantize.py; done means resnet50_quantized_qat completes eager training with the command without the scalar-type error.
