Changing directory in Google colab (breaking out of the python interpreter)

google colab default directory

how to get path in google colab
google colab drive

So I'm trying to git clone and cd into that directory using Google collab - but I cant cd into it. What am I doing wrong?

!rm -rf SwitchFrequencyAnalysis && git clone https://github.com/ACECentre/SwitchFrequencyAnalysis.git

!cd SwitchFrequencyAnalysis

!ls datalab/ SwitchFrequencyAnalysis/

You would expect it to output the directory contents of SwitchFrequencyAnalysis - but instead its the root. I'm feeling I'm missing something obvious - Is it something to do with being within the python interpreter? (where is the documentation??)

Demo here.

use

%cd SwitchFrequencyAnalysis

to change the current working directory for the notebook environment (and not just the subshell that runs your ! command).

you can confirm it worked with the pwd command like this:

!pwd

Use os.chdir. Here's a full example: https://colab.research.google.com/notebook#fileId=1CSPBdmY0TxU038aKscL8YJ3ELgCiGGju

Compactly:

!mkdir abc
!echo "file" > abc/123.txt

import os
os.chdir('abc')

# Now the directory 'abc' is the current working directory.
# and will show 123.txt.
!ls

Introduction to Colab and Python, Google Colab is a cloud-based service that allows the execution of Python code and In such notebooks, you can write interactive code, both in Python and other This is in addition to the ability to create new files and directories. Just like in a Google Doc, you can easily change the name of the notebook by simply​  I have a directory named ML in my drive: which has some of my colab-notebooks and some csv files which I want to load in my colab-notebook. But , when I use !pwd to find out the current folder, its output is as follows.!pwd /content When I use !ls .. The directory structure is as follows:

If you want to use the cd or ls functions , you need proper identifiers before the function names ( % and ! respectively) use %cd and !ls to navigate

.

!ls    # to find the directory you're in ,
%cd ./samplefolder  #if you wanna go into a folder (say samplefolder)

or if you wanna go out of the current folder

%cd ../      

and then navigate to the required folder/file accordingly

Welcome to this Colab where you will get a quick introduction to the Python is a Python development environment that runs in the browser using Google List the path of the current directory (pwd); Go to / (cd​) and list the content (ls -l) Resets your Python shell; Runtime -> Restart all runtimes. You can simply upload files manually to your Google Drive, and access them using codes above. Alternatively, you can use the following code: from google.colab import files uploaded = files.upload() Running Executable File. Copy the executable file to /usr/local/bin, and give yourself permission to execute it.

As others have pointed out, the cd command needs to start with a percentage sign:

%cd SwitchFrequencyAnalysis
Difference between % and !

Google Colab seems to inherit these syntaxes from Jupyter (which inherits them from IPython). Jake VanderPlas explains this IPython behaviour here. You can see the excerpt below.

If you play with IPython's shell commands for a while, you might notice that you cannot use !cd to navigate the filesystem:

In [11]: !pwd 
/home/jake/projects/myproject

In [12]: !cd ..

In [13]: !pwd 
/home/jake/projects/myproject 

The reason is that shell commands in the notebook are executed in a temporary subshell. If you'd like to change the working directory in a more enduring way, you can use the %cd magic command:

In [14]: %cd ..
/home/jake/projects

Another way to look at this: you need % because changing directory is relevant to the environment of the current notebook but not to the entire server runtime.

In general, use ! if the command is one that's okay to run in a separate shell. Use % if the command needs to be run on the specific notebook.

User Bob Smith, Thanks to Google's Colaboratory a.k.a. Google Colab!

  • Bob Smith's answer below is the right way to go, but if you're curious why the approach above didn't work: the issue is that each of the !-prefixed commands runs in its own subshell -- so the !cd starts a new shell, switches directories, and then kills that shell. The !ls then starts anew in the current directory. Doing !cd SwitchFrequencyAnalysis && ls would have worked, but using python's os.chdir is the cleaner approach here.
  • great! so, does /content and /root points to the same folder location. I mean I have a hard time understanding how the commands in googleColab related to the underlying Linux-VM filesystem. Since either you execute %cd /content | ls or !ls -la | pwd you will end up seeing /root/.kaggle which was created using the command set !pip install -U -q kaggle followed by !mkdir -p ~/.kaggle, that means ~/ which is home directory is equivalent to /root & /content, are those
  • could you please point to the source where I can find the above usage? also, I am looking for using pipeline operator | as we do use in bash shell scripting, any suggestions in that regards? Also, what the distinction between using % or !
