pyinstaller 打包openvino

1、安装openvino环境

    pip install openvino 

2、复制安装好的openvino库

    参考位置：
    安装python路径下\Lib\site-packages\openvino
    将openvino文件夹复制到代码同级目录下

3、修改运行库路径

    # 将运行库路径修改为同级目录下的openvino目录
    打开openvino/inference_engine/_init_.py
    修改：openvino_libs = [os.path.join(os.path.dirname(__file__), "..", "..", "openvino", "libs")]
    为：openvino_libs = [os.path.join(os.getcwd(),'openvino\\libs') ]
	# 增加python版本小于等于3.8环境配置，否则报错DLL load failed while importing ie_api: 找不到指定的模块。
	if (3, 8) <= sys.version_info:
		os.add_dll_directory(os.path.abspath(lib_path))
		os.environ["PATH"] = os.path.abspath(lib_path) + ";" + os.environ["PATH"]
    else:
    	os.environ["PATH"] = os.path.abspath(lib_path) + ";" + os.environ["PATH"]

4、打包代码

缺少库使用–hidden-import添加，如缺少 pkgutil:

    pyinstaller --onefile --hidden-import pkgutil demo.py

5、运行打包后的程序

将模型文件和openvino文件夹拷贝至exe程序所在目录

运行demo.exe

错误1：Empty weights data in bin file or bin file cannot be found!

    # 错误示例：
    File "ie_api.pyx", line 367, in openvino.inference_engine.ie_api.IECore.read_network
    File "ie_api.pyx", line 410, in openvino.inference_engine.ie_api.IECore.read_network
    RuntimeError: Empty weights data in bin file or bin file cannot be found!

解决方法：将openvinon模型bin文件拷贝至exe程序所在目录

错误2：No module named ‘openvino.inference_engine.constants’

    #错误示例：
    File "openvino\inference_engine\__init__.py", line 33, in <module>
    from .ie_api import *
    File "ie_api.pyx", line 27, in init openvino.inference_engine.ie_api
    ModuleNotFoundError: No module named 'openvino.inference_engine.constants'

解决方法：在openvino/inference_engine/_init_.py中from .ie_api import *下添加from .constants import * 如下：

    from .ie_api import *
    from .constants import *
