Sample script to download Kaggle files

kaggle_download.py

# Info on how to get your api key (kaggle.json) here: https://github.com/Kaggle/kaggle-api#api-credentials
!pip install kaggle
api_token = {"username":"USERNAME","key":"API_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 jigsaw-toxic-comment-classification-challenge
os.chdir('/content/competitions/jigsaw-toxic-comment-classification-challenge')
for file in os.listdir():
    zip_ref = zipfile.ZipFile(file, 'r')
    zip_ref.extractall()
    zip_ref.close()

Encontrei essa essência hoje, porque queria fazer o download do conjunto de dados kaggle no google colab, mas acabei usando uma abordagem diferente, espero que ajude:

!mkdir /root/.kaggle
!echo '{"username":"USERNAME","key":"API_KEY"}' > /root/.kaggle/kaggle.json

Dessa forma, você não precisa alterar o diretório de arquivos do kaggle json nas configurações do kaggle
e agora pode usar o kaggle para fazer o que precisar!

!kaggle datasets download -d owner/dataset-slug

É possível salvar o arquivo de download para usar em uma variável?

Setup and Download dataset

Imports

import json
import zipfile
import os

!pip install kaggle
api_token = {"username":"---Your Username","key":"Your API Key"}
!mkdir -p ~/.kaggle
with open('kaggle.json', 'w') as file:
    json.dump(api_token, file)
!cp kaggle.json ~/.kaggle/
!ls ~/.kaggle
!chmod 600 /root/.kaggle/kaggle.json
!kaggle datasets download -d heeraldedhia/groceries-dataset

• The dataset will now be present in the /content/ folder (you can see it using os.listdir())

Further, to extract the dataset,

for file in os.listdir():
    if '.zip' in file:
      zip_ref = zipfile.ZipFile(file, 'r')
      zip_ref.extractall()
      zip_ref.close()

• This will also place the files directly inside the /content/ folder

just set the variables...

#Set the enviroment variables
import os
os.environ['KAGGLE_USERNAME'] = "xxxx"
os.environ['KAGGLE_KEY'] = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
!kaggle datasets download -d iarunava/happy-house-dataset

thanks, It works but when I participate in competition:
import os
os.environ['KAGGLE_USERNAME'] = "xxxx"
os.environ['KAGGLE_KEY'] = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
!kaggle competition download -c xxxxxxxxxx
