Exception: Path to the weights doesn't exist or it's a directory

在用openvino推理时出现这个问题，不知道什么原因，我已经把.xml和图片都放在同一个路径下了，还是不行
C:\Program Files (x86)\Intel\openvino_2021.1.110\deployment_tools\demo\test_yolox>python openvino_inference.py -m yolox_10.xml -i assets\dog.jpg
[ INFO ] Creating Inference Engine

Exception: Path to the weights doesn't exist or it's a directory

Start with openvino_inference.py, especially line 89 where IECore.read_network is called, and reproduce the command from the issue in the demo/test_yolox directory. Check how the -m yolox_10.xml argument and its associated model files are resolved; done means the sample loads the network without the reported weights-path exception.
