具有独立python可执行文件(py2exe/pyinstaller)的OpenCV [英] OpenCV with standalone python executable (py2exe/pyinstaller)
问题描述
我有一个使用OpenCV从视频文件中获取帧进行处理的python程序.然后，我使用py2exe创建一个独立的可执行文件(也尝试使用pyinstaller并出现相同的错误).我的计算机和目标计算机都是Windows 7，但目标计算机未安装python.我使用OpenCV从视频文件中读取帧速率和单个图像.
I have a python program that uses OpenCV to get frames from a video file for processing. I then create a standalone executable using py2exe (also tried pyinstaller and got same error). My computer and the target computer are both Windows 7, but the target computer does not have python installed. I use OpenCV to read the frame rate and individual images from a video file.
问题:当我在目标计算机上运行可执行文件时，帧速率返回为0.0，而我无法读取帧.
Problem: When I run the executable on the target computer the frame rate is returned as 0.0 and I cannot read frames.
如果在目标计算机上安装了python，则可执行文件会按预期运行，否则会产生此错误.因此，似乎可执行文件中缺少某些内容，但是在创建可执行文件以指示可能缺少的内容时，我没有收到任何错误消息.
If python is installed on the target machine then the executable runs as expected, otherwise it produces this error. So it seems that something is missing in the executable, but I get no errors when creating the executable to indicate what might be missing.
其他报告过类似问题的人通常不包括numpy依赖项(并得到指示此错误的信息)，但我包括了numpy.我也尝试过包括整个PyQt4模块，因为它被列为OpenCV的python xy站点上的依赖项(我对代码的其他部分已经有了PyQt4的某些部分)，但这也不能解决问题.
Others who have reported similar issues usually have not included the numpy dependency (and get an error indicating this), but I have included numpy. I have also tried including the entire PyQt4 module since this is listed as a dependency on the python xy site for OpenCV (I already have parts of PyQt4 for other parts of the code) and this does not solve the problem either.
推荐答案
尝试使用pyinstaller，并使用pip进行下载:
Try using pyinstaller, download it using pip :
pip install pyinstaller
如果您不知道如何安装pip，请尝试下载具有内置pip的python 2.7.9或更高版本，但不要忘记将python路径添加到环境变量中，本文中将提到此过程:
if you don't know how to install pip , try downloading python 2.7.9 or above, which has inbuilt pip, but don forget to add python path to environment varibles, this procedure is mentioned in this post:
在安装pyinstaller之后，选择项目的主文件并运行此命令
After installing pyinstaller, select the main file of your project and run this command
pyinstaller yourprogram.py
它将使用应用程序文件创建文件夹，并命名您的文件名，最后确保在运行该命令时，numpy和opencv位于C文件夹中python27的lib-> site-packages文件夹中
it will create folder with application file naming your file name, and finally make sure that numpy and opencv are in lib->site-packages folder of your python27 in your C Folder while running that command
