问题描述
在Colaboratory中，有没有一种方法可以保存跨会话的库安装?如果可以，我该怎么办?我想总体上了解有关协作会话管理的更多信息.
In Colaboratory, is there a way to save library installations across sessions? If so how, can I do that? I'd like to learn more about Colaboratory session management in general.
目前，每次我必须导入时，例如一个cv2模块(因为默认情况下不可用)，我需要通过!apt=-get package-name重新安装带有!pip install opencv-python的模块以及提供共享库的依赖项.
Currently, everytime I have to import, for e.g. a cv2 module(as this is not available by default), I need to reinstall the module with !pip install opencv-python along with it's dependencies that provide for shared objects, through a !apt=-get package-name.
推荐答案
VM闲置一段时间后会超时，因此，您需要构造笔记本以在需要时安装自定义依赖项.
VMs time out after a period of inactivity, so you'll want to structure your notebooks to install custom dependencies if needed.
典型的模式是在笔记本顶部有一个单元，根据需要执行apt和pip安装命令.
A typical pattern is to have a cell at the top of your notebook that executes apt and pip install commands as needed.
对于opencv，它看起来像:
In the case of opencv, that would look something like:
!apt install -y -qq libsm6 libxext6 && pip install -q -U opencv-python
(在新的VM上大约需要7秒钟.)
(Takes ~7 seconds for me on a fresh VM.)
