Graph-Break Type

Short name describing what triggered the graph break

torch.switch: improper index

Values or code snippet captured at the break point

str(index)

Explanation of why the graph break was triggered

Expected index to be an int or a tensor with a single item but got {str(type(index))} with original python type {str(index.python_type())}.

Hints on how to resolve the graph break

Your code may result in an error when running in eager. Please double check that your code doesn’t contain a similar error when actually running eager/uncompiled. You can do this by removing the torch.compile call, or by using torch.compiler.set_stance("force_eager").
