torch.compiler.is_dynamo_compiling

torch.compiler.is_dynamo_compiling()

Indicates whether a graph is traced via TorchDynamo.

It’s stricter than is_compiling() flag, as it would only be set to True when TorchDynamo is used.

Example:

>>> def forward(self, x):
>>>     if not torch.compiler.is_dynamo_compiling():
>>>        ...logic that is not needed in a TorchDynamo-traced graph...
>>>
>>>     ...rest of the function...
