源码：

import acl

acl.init()

acl.rt.set_device(0)

context, _ = acl.rt.create_context(0)

model_path='/home/HwHiAiUser/桌面/yibo/3/yolov7_tiny.om'

model_id, _ = acl.mdl.load_from_file(model_path)

print(model_id)

acl.finalize()

acl.mdl.unload(model_id)

打包前运行print(model_id)为1

打包后运行print(model_id)为0

打包过程日志如下：
