Torch Dynamo backend compilation error with dynamic = True
Labels: triaged, oncall: pt2, module: dynamic shapes

### 🐛 Describe the bug

I am training a model described here
https://github.com/agunapal/examples/blob/pt2.0_example/pt2.0/mnist/main.py

with ```torch.compile(mode, dynamic=True)```

I am getting a compilation failure
