Graph-Break Type

Short name describing what triggered the graph break

setattr() on Tensor.requires_grad

Context

Values or code snippet captured at the break point

setattr({obj}, {name}, {val})

Explanation

Explanation of why the graph break was triggered

setattr() on Tensor.requires_grad not supported. Mutating requires_grad can introduce a new leaf from non-leaf or vice versa in the middle of the graph, which AOTAutograd does not currently know how to handle.

Hints

Hints on how to resolve the graph break

• It may be possible to write Dynamo tracing rules for this code. Please report an issue to PyTorch if you encounter this graph break often and it is causing performance issues.
