我在pc端训练了一个Yolov8的模型，实现了从pt到onnx到om的转换，在pc端做转换时下载的是"Ascend-cann-toolkit_8.2.RC1_linux-x86_64.run"这个版本，在转换成om格式后，我在板子上运行这个om模型出现了如下的报错：

(base) HwHiAiUser@orangepiaipro:~/yolo_activate$ python run_infer4.py --mode camera

init resource stage:

Init resource success

Traceback (most recent call last):

    if self._is_destroyed:

AttributeError: 'AclLiteModel' object has no attribute '_is_destroyed'

acl resource release all resource

Release acl resource success

关键报错在“acl.mdl.load_from_file failed ret_int=500002”这一行。

此外我又在香橙派端对我训练好的这个yolov8模型做了一次转换，但这次转换出的om模型在香橙派上运行时可以成功使用。于是出现了在pc端转换的om模型无法正常运行，在板端转换的模型可以运行。

求原因和解决办法！！！
