I don’t know anything about ONNX, but it seems like your input has 4 dimensions + your mode being bilinear will result in this line 51 being called, which is apparently not supported by ONNX yet?
To be more precise, either the operation upsample_bilinear2d is not supported yet, or the operation upsample_bilinear2d with option align_corners=True is not supported yet…
