[在Google Colab中使用IJulia时如何安装Google驱动器？

Question

我正在尝试让Julia在合作实验室中工作。我想像使用IJulia一样在IPython中将gdrive挂载到colab。在ipython中，我可以按照以下步骤操作：

from google.colab import drive
drive.mount('/content/gdrive')

我尝试以下操作：

using PyCall
clb = pyimport("google")
clb.colab.drive.mount("/content/gdrive")

两个都不起作用。

实现此目的的一种方法是在安装Julia之前先安装Google驱动器，当默认Runtime type为Python时，运行：

from google.colab import drive
drive.mount('/content/gdrive')

这样，即使将Runtime type更改为Julia之后，Google驱动器仍会保持挂载状态，直到您更改Hardware acceleration或会话丢失。
