How to run shell script file on ipython at Google Colab

问题

I'd like to know how to run a bash sell script file on ipython(jupyter notbook) at Google Colab. I downloded an Deep-learning codes package from github and upload them on my google drive and I mount the goole drive on Google Colab The code package includes'*.py' python codes and 'fn.sh' script file. By executing the script file the python codes can be executed.

I tried os.system('fn.sh') and subprocess.call('fn.sh') on the ipython prompt at Google Colab but they doesn't work like below.

1)

import os os.system('drive/DL/denet-master/examples/simple-cifar10.sh') 32256

2)

import subprocess subprocess.call('drive/DL/denet-master/examples/simple-cifar10.sh') OSError: [Errno 8] Exec format error: 'drive/DL/denet-master/examples/simple-cifar10.sh'

回答1:

In Colab, you can invoke shell commands using either ! or %%shell.

Your invocation above would be:

!drive/DL/denet-master/examples/simple-cifar10.sh

Here's an example notebook:
