Thank you for your answer, but I don’t think it’s the.onnx file that doesn’t download because the.onnx file does exist and executing other commands does produce output files (such as resnet50-v2-7-tvm. Tar, Prediction.npz) and the corresponding statement output.In other words, all the steps prior to auto-tuning can be performed, although there are still some caveats… Anyway, thank you for your help and welcome to continue discussing this issue.
