Using Kaggle Datasets in Google Colab

问题

Is it possible to use any datasets available via the kaggle API in Google Colab? I see the Kaggle API is used in this Colab notebook, but it\'s a bit unclear to me what datasets it provides access to.

回答1:

Step-by-step --

1. Create an API key in Kaggle.

   To do this, go to kaggle.com/ and open your user settings page.

2. Next, scroll down to the API access section and click generate to download an API key. This will download a file called kaggle.json to your computer. You'll use this file in Colab to access Kaggle datasets and competitions.

3. Navigate to https://colab.research.google.com/.

4. Upload your kaggle.json file using the following snippet in a code cell:

   from google.colab import files files.upload()

5. Install the kaggle API using !pip install -q kaggle

6. Move the kaggle.json file into ~/.kaggle, which is where the API client expects your token to be located:

   !mkdir -p ~/.kaggle !cp kaggle.json ~/.kaggle/

7. Now you can access datasets using the client, e.g., !kaggle datasets list.

Here's a complete example notebook of the Colab portion of this process: https://colab.research.google.com/drive/1DofKEdQYaXmDWBzuResXWWvxhLgDeVyl

This example shows uploading the kaggle.json file, the Kaggle API client, and using the Kaggle client to download a dataset.

You should be able to access any dataset on Kaggle via the API. In this example, only the datasets for competitions are being listed. You can see that datasets you can access with this command:

kaggle datasets list

You can also search for datasets by adding the -s tag and then the search term you're interested in. So this would give you a list of datasets about dogs:

kaggle datasets list -s dogs

You can find more information on the API and how to use it in the documentation here.

Hope that helps! :)

I have this tutorial to use Kaggle API on Google Colab directly without downloading and uploading the data set through your local machine. Kaggle API + Colaboratory

回答4:

Have a look at this.

It uses official kaggle api behind scene, but automates the process so you dont have to re-download manually every time your VM is taken away. Also, another issue i faced with using Kaggle API directly on Colab was the hassle of transferring Kaggle API token via Google Drive. Above method automates that as well.

First of all, run this command to find out where this colab file exists, how it executes. !ls -d $PWD/* It will show /content/data /content/gdrive /content/models In other words, your current directory is root/content/. Your working directory(pwd) is /content/. so when you do !ls, it will show data gdrive models. FYI, ! allows you to run linux commands inside colab.

Google Drive keeps cleaning up the /content folder. Therefore, every session you use colab, downloaded data sets, kaggle json file will be gone. That's why it's important to automate the process, so you can focus on writing code, not setting up the environment every time.

Run this in colab code block as an example with your own api key. open kaggle.json file. you will find them out.

# Info on how to get your api key (kaggle.json) here: https://github.com/Kaggle/kaggle-api#api-credentials
!pip install kaggle
{"username":"seunghunsunmoonlee","key":""}
import json
import zipfile
import os
with open('/content/.kaggle/kaggle.json', 'w') as file:
    json.dump(api_token, file)
!chmod 600 /content/.kaggle/kaggle.json
!kaggle config path -p /content
!kaggle competitions download -c dog-breed-identification
os.chdir('/content/competitions/dog-breed-identification')
for file in os.listdir():
    zip_ref = zipfile.ZipFile(file, 'r')
    zip_ref.extractall()
    zip_ref.close()

Then run !ls again. You will see all data you need. Hope it helps!

Combined the top response to this Github gist as Colab Implementation. You can directly copy the code and use it.

How to Import a Dataset from Kaggle in Colab

Method:

First a few things you have to do:

1. Sign up for Kaggle
2. Sign up for a competition you want to access data from (for example LANL-Earthquake-Prediction competition).
3. Download your credentials to access Kaggle API as kaggle.json

# Install kaggle packages
!pip install -q kaggle
!pip install -q kaggle-cli

# Colab's file access feature
from google.colab import files

# Upload `kaggle.json` file
uploaded = files.upload()

# Retrieve uploaded file
# print results
for fn in uploaded.keys():
  print('User uploaded file "{name}" with length {length} bytes'.format(
      name=fn, length=len(uploaded[fn])))

# Then copy kaggle.json into the folder where the API expects to find it.
!mkdir -p ~/.kaggle
!cp kaggle.json ~/.kaggle/
!chmod 600 ~/.kaggle/kaggle.json
!ls ~/.kaggle

Now check if it worked!

#list competitions
!kaggle competitions list -s LANL-Earthquake-Prediction

To download the competitve data on google colab from kaggle. I'm working on google colab and I've been through the same problem. but i did two tings .

First you have to register your mobile number along with your country code. Second you have to click on last submission on the kaggle dataset page Then download kaggle.json file from kaggle.upload kaggle.json on the google colab After that on google colab run these code is given below.

!pip install -q kaggle
!mkdir -p ~/.kaggle
!cp kaggle.json ~/.kaggle/ 
!chmod 600 ~/.kaggle/kaggle.json 
!kaggle competitions download -c web-traffic-time-series-forecasting

回答8:

after the steps (1-6) above, to use dataset from a particular competition in colab, you can use the command:

!kaggle competitions download -c elo-merchant-category-recommendation

( elo-merchant-category-recommendation is the name of the competition. )
