在Colab上导入Kaggle数据集时出错

执行以下行时

!pip install kaggle
!kaggle competitions download -c dogs-vs-cats -p /content/

我收到以下错误消息,

Traceback (most recent call last):
File "/usr/local/bin/kaggle", line 7, in 
from kaggle.cli import main
File "/usr/local/lib/python3.6/dist-packages/kaggle/__init__.py", line 23, in

我不知道刚发生了什么......同样的线路之前工作得很好.这是我第一次发现这个问题.

它突然停止在这里工作.显然,kaggle api没有在正确的位置搜索kaggle.json文件.由于我在colab笔记本中使用了kaggle api,我正在导入kaggle.json,如下所示:

from googleapiclient.discovery import build
import io, os
from googleapiclient.http import MediaIoBaseDownload
from google.colab import auth

auth.authenticate_user()

drive_service = build('drive', 'v3')
results = drive_service.files().list(
        q="name = 'kaggle.json'", fields="files(id)").execute()
kaggle_api_key = results.get('files', [])

filename = "/content/.kaggle/kaggle.json"
os.makedirs(os.path.dirname(filename), exist_ok=True)

request = drive_service.files().get_media(fileId=kaggle_api_key[0]['id'])
fh = io.FileIO(filename, 'wb')
downloader = MediaIoBaseDownload(fh, request)
dOne= False
while done is False:
    status, dOne= downloader.next_chunk()
    print("Download %d%%." % int(status.progress() * 100))
os.chmod(filename, 600)

它运作得很好.但现在,kaggle api在这个位置搜索kaggle.json:

~/.kaggle/kaggle.json

所以,我只需将我下载的文件移动/复制到正确的位置:

!mkdir ~/.kaggle
!cp /content/.kaggle/kaggle.json ~/.kaggle/kaggle.json

它又开始工作了.

这个简单的事情在Google Cola上为我完成了。

!echo '{"username":"USERNAME","key":"KEY"}' > ~/.kaggle/kaggle.json
!kaggle datasets download -d mmoreaux/environmental-sound-classification-50

-

编辑，可能已更改为：

!echo '{"username":"USERNAME","key":"KEY"}' > /root/.kaggle/kaggle.json
!kaggle datasets download -d mmoreaux/environmental-sound-classification-50
