Google Colab：从另一个Python文件调用函数

Question

我想DataProcesser从load_data.pypython 文件运行一个函数，该文件可以在我的 google 驱动器路径中找到gdrive/My\ Drive/Colab\ Notebooks/CODEX/source/。

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

# Custom functions/classes
path_to_module = 'gdrive/My\ Drive/Colab\ Notebooks/CODEX/source/'  # Path where all the .py files are, relative to the notebook folder
sys.path.append(path_to_module)
from load_data import DataProcesser

追溯：

Answer 1

您可能不需要转义字符串中的空格path_to_module，但 Colab 看到的路径可能不同。如果您展开filesColab 中的选项卡，您可以导航到 Google Drive 中的文件。然后您可以右键单击您想要的文件或文件夹并执行操作Copy path。然后您可以将其粘贴到定义的单元格中path_to_module。

可以说，它对我有用；但我的路径 ( .../tmp) 会与你的不同。

from google.colab import drive
drive.mount('/content/gdrive')
import sys    
path_to_module = '/content/gdrive/MyDrive/tmp'
sys.path.append(path_to_module)
from mypy import myfunc

我导航到该tmp文件夹​​并复制属性，然后将其粘贴到代码中。
