Add graph mode debugging hints and troubleshooting doc#39
Merged
Conversation
Surfaces actionable hints (export_with_no_grad toggle, dynamic_shapes, eager fallback) in the torch.export.export failure message, and includes the source module name when a graph partition annotation fails so it can be excluded via module_name_configs. Adds a Graph Mode Troubleshooting doc under a new Debugging doc section.
The link still pointed at the old utils/ location after this branch moved the doc to debugging/.
Link "Graph execution mode" to the execution-modes section, note that export failures may warrant fixing the model definition (since the same construct can block coreai-torch conversion later), and drop the "our"/"report against torch" phrasing per review.

…tils torch.export's insert_deferred_runtime_asserts synthesizes one SymInt mul per shape-runtime assertion under a shared torch_fn tag, collapsing several into a single SourcePartition. The new strict "exactly 1 call function node" check treated this as an error, regressing test_prepare_with_symint_mul_partition_collision (and CI). These SymInt nodes carry no tensor value to annotate, so picking any one of them is safe, matching the pre-existing lenient behavior for this case.
