问题描述
我正在尝试让Julia在合作实验室中工作.我想像使用IJulia时在IPython中一样将gdrive挂载到colab.在ipython中，我可以按照以下步骤进行操作:
I am trying to get Julia working in colab. I want to mount gdrive to colab just like in IPython when using IJulia. In ipython I can do it as follows:
from google.colab import drive
drive.mount('/content/gdrive')
我尝试了以下操作:
using PyCall
clb = pyimport("google")
clb.colab.drive.mount("/content/gdrive")

两个都不起作用.
推荐答案
实现此目的的一种方法是，在默认情况下Runtime type是Python时，通过运行以下命令，在安装Julia之前先安装Google驱动器:
One way to achieve this is to mount google drive before installing Julia, when default Runtime type is Python by running:
from google.colab import drive
drive.mount('/content/gdrive')
这样，即使将Runtime type更改为Julia之后，Google驱动器仍会挂载，直到您更改Hardware acceleration或会话丢失为止.
That way, even after Runtime type is changed to Julia, google drive remains mounted until you change Hardware acceleration or session is lost.
