Graph-Break Type

Short name describing what triggered the graph break

torch.compile call with > 1 args

Context

Values or code snippet captured at the break point

args={args}, kwargs={kwargs}

Explanation

Explanation of why the graph break was triggered

Attempted to call torch.compile with > 1 args. Dynamo does not support this.

Hints

Hints on how to resolve the graph break

• Remove the torch.compile call or its additional args.
• 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.

Additional Information

Example code that causes the graph break is:

import torch

def g(x):
    return x + 1

@torch.compile(backend="eager") 
def f(x):
    return torch.compile(g, False)(x)

f(torch.randn(10, 10))
