pyinstaller打包openvino 2021.4.2-526互联

打包准备

1. 安装pyinstaller

conda create -n opinstall python=3.7 -y
conda activate opinstall

pip install openvino
pip install pyinstaller

2. 将openvino文件夹复制到代码同级目录下
D:\ProgramData\anaconda3\envs\openvino_install\Lib\site-packages\openvino 拷贝至 F:\openvino_install

3. 修改配置
# 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"]
》增加：
