Can't import custom functions in CoLab Notebook

[harjeeth]

For some reason any linking to images stored in another directory doesn't seem to break, but it does when it comes to custom packages/functions:

Any idea on how to solve this?

[gahjelle]

Does it work if you specify the folder as well in the import? I.e. from python.plot_functions import make_plot?

[gahjelle]

Another option might be to explicitly add the python subfolder to sys.path. Something along the lines of

import sys
sys.path.append("python")
from plot_functions import make_plot

Ah, sorry, I see you've already tried this 😊

[gahjelle]

It might also be that the working directory of the notebook is not where you expect? What does

import pathlib
print(pathlib.Path.cwd())

tell you?

[harjeeth]

@gahjelle this:

import pathlib
print(pathlib.Path.cwd())

gives me:

>>> /content

and

print(sys.path)

is

>>> ['./python', './python', '', '/env/python', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', '/usr/local/lib/python3.6/dist-packages/IPython/extensions', '/content/.ipython']

[gahjelle]

So the /content folder seems to be where colab puts stuff. You can also do print(list(pathlib.Path.cwd().iterdir())) to see what is inside that folder. Do you see your python file there?

[harjeeth]

What I see running print(list(pathlib.Path.cwd().iterdir())) is

>>> [PosixPath('/content/datalab'), PosixPath('/content/.forever'), PosixPath('/content/.rnd'), PosixPath('/content/.ipython'), PosixPath('/content/.config'), PosixPath('/content/.cache'), PosixPath('/content/.local')]

[gahjelle]

Ok, I don't see any of your directories there. So it seems quite clear that those are not a part of colab. So something like Patrick's idea of using wget to download it on the fly seems necessary.

Or just include the code in the notebook instead 😊
