Python 谷歌云虚拟机-安装openCV

我使用Google App Engine和Python来托管一些后端脚本并在数据存储中存储数据，我需要利用openCV进行一些更高级的媒体操作

我正在尝试切换到谷歌云虚拟机平台，但我在理解如何安装openCV方面遇到了困难

今天早些时候，我在VM Cloud Shell上尝试了：

sudo apt-get install python-opencv

这似乎是可行的，在列出我的python模块之后，我得到了：

如您所见，cv和cv2已列出。然后我试着：

>>> from cv2 import *

我也试过：

>>> import cv2

两者似乎都正确地导入了模块

然而，数小时后，我再次尝试导入cv2，但未找到，因此我再次运行模块检查，并得到：

如果有人知道关于如何正确安装openCV并将其导入我的python脚本的完整文档帮助，请发布该链接！我从谷歌云文档中知道，我应该能够在我的虚拟机上使用openCV

对于如何设置Dockerfile和requirements.txt文件以正确使用openCV，有一些更详细的说明也会很有帮助。同样，上面链接的谷歌云文档中也提到了这一点，但从未详细解释过

谢谢

只是一个正在运行的。这是一种快速运行gcloud命令的方法，可以与您的谷歌云项目资源进行交互和管理。但它不包含实际的项目资源

云Shell的会话仅在处于活动状态时保持，并在一小时不活动后终止。因此，在Cloud Shell虚拟机上导入openCV完全独立于您的项目，并且不会以任何方式持久化到该项目

为了将openCV应用程序部署到应用程序引擎，您需要使用openCV应用程序目录中的“”命令

作为openCV的一种替代方案，我们现在提供了一种为您的应用程序提供分析图像、视频、语音、文本等功能的方法

如果安装在主目录中，它不会持续存在吗？是的，如果使用，它将在会话之间持续存在。尽管如果您不定期访问Cloud Shell，$HOME directory持久存储可能会被回收，正如文档中所述。@Jordan当您提到定期

的确切时间范围时，

文档中没有提到定期意味着什么的确切时间范围
