Start with the BlueFog High Level API Introduction example referenced in the issue and reproduce the reported ValueError. Trace the call that supplies self_weight and src_weights, then verify the example completes without the IPEngine error. No source file or test is named in the report, so locating the relevant entry point is part of the investigation.
