How to export data frames which are created in google colab to your local machine?
I have cleaned a data set on google colab. Now I want to export the data frame to my local machine.
df.to_csv is saving file to the virtual machine and not my local machine.
回答1:
Try this
from google.colab import files
files.download("data.csv")
Update(Sep 2018): now it's even easier
- open the left pane
- select 'Files' tab
- click 'Refresh'
- right click the file, then download

Try this:
First you can save the file using pandas to_csv functionality later on you can download that file using google colab files functionality.
from google.colab import files
df.to_csv('filename.csv')
files.download('filename.csv')

You can download the csv to your associated google drive. First you must install PyDrive.
!pip install -U -q PyDrive
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from google.colab import files
from oauth2client.client import GoogleCredentials
auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)
This will generate a token in a browser for you to then paste into an input box that will be shown in your notebook.
Save your pandas data frame
df.to_csv('mydataframe.csv', sep='\t')
To keep things neat you can create a new folder in your drive and then use the following:
file_list = drive.ListFile({'q': "'root' in parents and trashed=false"}).GetList()
for file1 in file_list:
print('title: %s, id: %s' % (file1['title'], file1['id']))
which will list the files and folders in your google drive and their id that you will need for the following step.
file = drive.CreateFile({'parents':[{u'id': 'id of folder you want to save in'}]}) file.SetContentFile("mydataframe.csv")
file.Upload()
It will now be in your google drive in the given folder.
