python -m onnxsim 报错：RuntimeException: [ONNXRuntimeError] : 6 : RUNTIME_EXCEPTION ，UpsampleMode) const scale >= 1 was false. Scale value should be greater than or equal to 1.

RuntimeException: [ONNXRuntimeError] : 6 : RUNTIME_EXCEPTION : Exception during initialization: /Users/runner/work/1/s/onnxruntime/core/providers/cpu/tensor/upsample.h:271 void onnxruntime::UpsampleBase::ScalesValidation(const std::vector<float> &, const onnxruntime::UpsampleMode) const scale >= 1 was false. Scale value should be greater than or equal to 1.


原因是在

torch.onnx.export 的时候没有配置opset_version参数，默认是9，如果pytorch >=1.3.0,可以配置成11，否则配置成10

@hariharans29 Thank you for your reply, I re-generated the onnx file. The above mentioned problem happens with opset=9, but when setting opset=10, everything goes on well as expected.
