Hi @jwfromm @mbrookhart , thanks for the response and effort on this case. The PR looks good to me. I am currently working on a research project related to TVM, would like to make more contributions to TVM and also looking forward to the feedback from community. |

These two errors that you generated were excellent real bugs with the importer and were very easy to understand and replicate with your post. If they're being auto-generated they look excellent! |

Hi @luyaor you are welcome to poke at pytorch frontend too, I hope it is more robust than onnx frontend :) |

Our current prelu converter assumes that incoming data is in NCHW format and that the slope will have C total elements. Neither of these are actual requirements for ONNX PreLu. As pointed out in #7202, our converter fails in other cases. This PR makes our importer prelu compliant with the onnx spec.
