板子是Atlas200DK A2，CANN是8.0.RC1.alpha003。

原本在Ubuntu下可以运行转为onnx，想直接在开发板上转就发生如下报错

model_data/yolov5_s.pth model, and classes loaded. 

Starting export with onnx 1.16.1. 

Simplifying with onnx-simplifier 0.4.36.

查了下是四核，于是添加了

import os 

import onnxruntime as ort 

os.environ['OMP_NUM_THREADS'] = '4' 

os.environ['MKL_NUM_THREADS'] = '4'

，但仍然是一样的错误。

求解答
