python - 下载 Kaggle 数据集

问题描述

我想下载一个 Kaggle 数据集。我生成了 Kaggle.json 文件，但不幸的是我没有驱动器（我不能使用它）。是否有任何选项可以直接在代码中生成用户名和令牌？例如我试过这个

x =  '{"username":"<USERNAME>","key":"<TOKEN>"}'
y = json.loads(x)
api = KaggleApi(y)
api.authenticate()
files = api.competition_download_files("two-sigma-financial-news")

错误是

  ---------------------------------------------------------------------------
    OSError                                   Traceback (most recent call last)
    <ipython-input-6-237de0539a08> in <module>()
          1 api = KaggleApi(y)
    ----> 2 api.authenticate()
          3 files = api.competition_download_files("two-sigma-financial-news")
    
    /usr/local/lib/python3.6/dist-packages/kaggle/api/kaggle_api_extended.py in authenticate(self)
        164                 raise IOError('Could not find {}. Make sure it\'s located in'
        165                               ' {}. Or use the environment method.'.format(
    --> 166                                   self.config_file, self.config_dir))
        167 
        168         # Step 3: load into configuration!
    
        OSError: Could not find kaggle.json. Make sure it's located in /root/.kaggle. Or use the environment method.

但这是不对的。有人可以帮我吗？我正在使用 Colab，但我不想将 JSON 文件存储在我的 Google Drive 中。是否有任何选项可以直接生成 JSON 文件？

提前致谢。

解决方案

也许这篇文章有帮助：https ://www.kaggle.com/general/51898 它链接到这个脚本：

# 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()
