## Description When compiling following model, TVM will produce wrong result. The model(with ONNX as frontend) with error is as follows, check bug.onnx in [reproduce.zip](https://github.com/apache/tvm/files/9259136/reproduce.zip) The semantic of the model is to sum up input tensors with five times. For example, the first element in the input tensor is -0.7491791248321533, so the first element in output should be -0.7491791248321533 * 5 = -3.74, however, the element in the output is -11.986866. <img width="1020" alt="image" src="https://user-images.githubusercontent.com/7541296/182831586-cf464fff-2d42-465d-9f9a-b19041879f98.png";> ## How to reproduce ### Expected behavior Output should be as follows: ``` [array([[[[-3.7458956 , 2.2319033 , 4.721547 ]], [[-2.5541332 , -1.010938 , -1.2561022 ]], [[-2.432028 , 2.1270378 , -2.2868755 ]]], [[[ 0.14414614, -3.7024972 , 3.4796305 ]], [[ 1.8737267 , 0.38758603, 1.1408547 ]], [[-2.7563024 , 3.4405584 , -3.7759078 ]]]], dtype=float32)] ``` ### Actual behavior This is the output of running model with TVM compiled. ``` [[[[-11.986866 7.142091 15.108952 ]] [[ -8.173226 -3.2350018 -4.019527 ]] [[ -7.78249 6.806521 -7.3180013 ]]] [[[ 0.46126765 -11.847991 11.134817 ]] [[ 5.9959254 1.2402753 3.6507351 ]] [[ -8.820168 11.009787 -12.082905 ]]]] ``` ### Environment Python3, with tvm, onnx, numpy, onnxruntime(optional) 1. Download [reproduce.zip](https://github.com/apache/tvm/files/9259136/reproduce.zip) 2. Run `python check.py`. To check with the actual output, you could check with the commented code. -- This is an automated message from the Apache Git Service.
