Description
pcard-89456
During the validation of the multimodal
Qwen2VL, the dynamic to static encountered an error when running operator offlash_attn_unpaddedin pir mode. The reason was that the input of operator offlash_attn_unpaddedlacked distributed attributes. Tracing along the calculation graph, it was found that the distributed attributes would be lost afterpd_op.expand. Further examination of the code reveals that ExpandOp (ExpandOp::InferMeta, etc.) under PIR is handwritten, and there is no processing for distributed attributes in the handwritten logic (regular OP generated code will have relevant processing). The reason for handwriting is described in PR #58767 , so this PR will add processing for distributed attributes in ExpandOp::InferMeta.
