onnxruntime:, inference_session.cc:1294 operator()] Exception during initialization: std::bad_alloc_onnxsim bad_alloc

在某嵌入式设备中用onnxtime推理yolov5时报如下的错误

Exception during initialization: std::bad_alloc

在某搜索引擎上搜索，得到RUNTIME_EXCEPTION : Exception during initialization · Issue #4486 · microsoft/onnxruntime · GitHub

这个答案提醒了我，于是怀疑是不是这个板子的内存不够，于是查看板子内存

 发现板子剩余内存只有60M，而算法运行需要将近300M内存。
