`torch.compile` + `torch.no_grad` not working for Mask R-CNN
Labels: triaged, ezyang's list, oncall: pt2, module: dynamic shapes

### 🐛 Describe the bug

Greetings,

I have been trying to get `torch.compile` to work with a Mask R-CNN model, but have not been able to do so in combination with gradient disabling. An error also occurs if I use `torch.inference_mode` instead of `torch.no_grad`. I've seen it mentioned that `torch.inference_mode` does not work with `torch.compile` ([here](https://github.com/pytorch/pytorch/issues/90882)), but not for gradient disabling in general. The following snippet should reproduce the error:

```python
import torch
import torchvision

device = "cuda:0"

x = torch.rand(1, 3, 800, 800, device=device)

model = torchvision.models.detection.maskrcnn_resnet50_fpn()
model = model.to(device)
model = torch.compile(model)
model.eval()

# This works
# _ = model(x)

# This does not
with torch.no_grad():
    _ = model(x)
```

The output:

```

Set torch._dynamo.config.verbose=True for more information


You can suppress this exception and fall back to eager by setting:
    torch._dynamo.config.suppress_errors = True

```

I've tried the same test using a different model (`torchvision.models.resnet50`), and in
this case the error does not happen. So it could perhaps be specific to the Mask R-CNN
model.
