我正在尝试将一些数据从kaggle导入到笔记本中。我收到的错误是未经授权的401，但是我已经接受了比赛规则，并且能够下载数据。
这是我正在运行的代码：
from kaggle.api.kaggle_api_extended import KaggleApi
api = KaggleApi()
files = api.competition_download_files("twosigmanews")
api.competitions_submit("submission.csv", "my submission message", "twosigmanews")
编辑：添加了更多错误：无论我要导入哪个kaggle数据，我都会遇到相同的错误。

我认为比赛的名称是错误的。试试：
from kaggle.api.kaggle_api_extended import KaggleApi
api = KaggleApi('copy and paste kaggle.json content here')
api.authenticate()
files = api.competition_download_files("two-sigma-financial-news")
答案 1 :(得分：1)
在查看源代码时，我发现了此类。我认为笔记本在调用KaggleApi（）时不会自动进行身份验证，因此您需要在API上调用身份验证功能以连接到Kaggle API。
尝试：
api = KaggleApi()
api.authenticate()
通话后，我能够连接并下载示例。
答案 2 :(得分：1)
您尚未为您的代码提供任何授权，例如您的用户ID，密码和最重要的身份验证密钥。身份验证密钥在用户ID和其Kaggle密码之后给出。
将Kaggle API分配给名为“ api”的变量后，可以从api.authenticate()函数获得Kaggle身份验证。
答案 3 :(得分：0)
您的username和key未提供或无效。
转到https://www.kaggle.com/username/account并创建新的API令牌。 kaggle.json文件将被下载。将其放在~/.kaggle/kaggle.json或C:\Users\User\.kaggle\kggle.json中。
此外，您还必须在“规则接受”部分中单击“我理解并接受”以获取要下载的数据。
答案 4 :(得分：0)
这是从kaggle API导入数据的另一种Python方法。我假设您正在使用Linux OS进行云实例。
这是我的操作方式：
kaggle.json文件：https://www.kaggle.com/<username>/account 运行此代码，并确保您在正确的目录中具有kaggle.json。
import json
import os
os.chdir("~/.kaggle")
data = {"username":"username","key":"tockenvalue"} # get this data from kaggle.json file
with open('kaggle.json', 'w') as outfile:
json.dump(data, outfile)
上，cd将目录更改为要放置数据的位置，然后在终端中键入：
kaggle competitions download -c two-sigma-financial-news
每次您想从Kaggle API导入数据时，此功能就可用。
