Hi !

For me simply run the cell:

!curl -s https://course.fast.ai/setup/colab | bash

Works perfectly !

All the steps are listed here if you want more information

Maybe then this is what your are looking for:

No luck…
I followed below steps

!git clone https://github.com/fastai/fastai_docs.git in colab … which created fastai_docs folder under ./content
from google.colab import drive
drive.mount(’/content/fai/’, force_remount=True)
then i copied using cp command all files to exp folder that i created on mounted path My drive/colabnotebooks/exp

For notebooks in part 2, I have been using Colab.

I put the notes here:

github.com

qcai2002/FastaiNotes/blob/master/colab.txt

https://course.fast.ai/start_colab.html
has excellent instructions.

Since each notebook imports the library built in previous notebooks, start with 00_exports.ipynb

Here are the steps:
1) Sign into google drive 

2) go to Colab welcome page
https://colab.research.google.com/notebooks/welcome.ipynb#recent=true

3) Click github tub then paste this url: 
https://github.com/fastai/fastai_docs/blob/master/dev_course/dl2/00_exports.ipynb

4) Select 00_exports.ipynb, click “File -> save a copy in drive”. The newly saved copy is automatically named 
“Copy of 00_exports.ipynb”. 
Close the original copy. Rename the newly saved copy to the original name, i.e. remove the “Copy of “ from the file name. 
This is because the end of the notebook has this line:
!python notebook2script.py 00_exports.ipynb 
If we have a different file name, it’ll say “can’t find notebook 00_exports.ipynb”

This file has been truncated. show original

Here is how I got the notebooks to run: Colab setup for Part 2 2019

I am probably reinventing the wheel here.

Goto Colab
Select lesson 8 - https://colab.research.google.com/github/fastai/course-v3/blob/master/nbs/dl2/00_exports.ipynb
Save to drive. It becomes Copy of 00_exports.ipynb. This is saved to folder Colab Notebooks on your Google Drive.
Rename it to 00_exports.ipynb (File->Rename)

On a new tab locate

github.com

fastai/course-v3/blob/master/nbs/dl2/notebook2script.py

#!/usr/bin/env python

import json,fire,re
from pathlib import Path
import io

def is_export(cell):
    if cell['cell_type'] != 'code': return False
    src = cell['source']
    if len(src) == 0 or len(src[0]) < 7: return False
    #import pdb; pdb.set_trace()
    return re.match(r'^\s*#\s*export\s*$', src[0], re.IGNORECASE) is not None

def getSortedFiles(allFiles, upTo=None):
    '''Returns all the notebok files sorted by name.
       allFiles = True : returns all files
                = '*_*.ipynb' : returns this pattern
       upTo = None : no upper limit
            = filter : returns all files up to 'filter' included
       The sorting optioj is important to ensure that the notebok are executed in correct order.

This file has been truncated. show original

Next retrieve the source code and select the RAW option to get the text. Save this to your computer and upload it to the folder Colab Notebooks on your Google Drive

Return to Colab and make Colab Netbooks the working directory

!curl -s https://course.fast.ai/setup/colab | bash
!pip install fire
from google.colab import drive
drive.mount(’/content/gdrive’, force_remount=True)
%cd “/content/gdrive/My Drive/Colab Notebooks/”

Now you can continue the lesson

#export
TEST = ‘test’

!python notebook2script.py 00_exports.ipynb

import json
d = json.load(open(‘00_exports.ipynb’,‘r’))[‘cells’]
