运行/tools/quantization_tool/examples/example.py 报错MatMul算子在esp-dl上不支持 (AIV-599)

报错信息：

请问这是什么原因造成的，代码没有改动过

Did you face this problem during setup? #121

Hi, example.py 中会调用 optimized_model_path = optimize_fp_model(model_path) 这个函数来将 matmul 转为 gemm，函数定义在 https://github.com/espressif/esp-dl/blob/master/tools/quantization_tool/optimizer.py，检查一下路径之类的有没有问题吧

我也出现了同样的问题，然后我原本的环境是python=3.7，onnx=1.13.1。然后我将onnx降低版本为1.9.0后，问题解决了
