将代理传递给 Seaborn

Question

我正在seaborn用于数据可视化。但它失败了它在文档中的样本数据

import seaborn as sns
sns.set()
tips = sns.load_dataset("tips")

Traceback (most recent call last):
  File "databaseConnection.py", line 35, in <module>
    tips = sns.load_dataset("tips")
  File "C:\python3.7\lib\site-packages\seaborn\utils.py", line 428, in load_dataset
    urlretrieve(full_path, cache_path)
  File "C:\python3.7\lib\urllib\request.py", line 247, in urlretrieve
    with contextlib.closing(urlopen(url, data)) as fp:
  File "C:\python3.7\lib\urllib\request.py", line 222, in urlopen
    return opener.open(url, data, timeout)
  File "C:\python3.7\lib\urllib\request.py", line 525, in open
    response = self._open(req, data)
  File "C:\python3.7\lib\urllib\request.py", line 543, in _open
    '_open', req)
  File "C:\python3.7\lib\urllib\request.py", line 503, in _call_chain
    result = func(*args)
  File "C:\python3.7\lib\urllib\request.py", line 1360, in https_open
    context=self._context, check_hostname=self._check_hostname)
  File "C:\python3.7\lib\urllib\request.py", line 1319, in do_open
    raise URLError(err)
urllib.error.URLError: <urlopen error [Errno 11001] getaddrinfo failed>

那是因为我在代理后面，但是我怎么能要求seaborn使用代理呢？

您可以手动下载文件。

用

import seaborn as sns
print(sns.utils.get_data_home())

找出您的 seaborn 数据的文件夹，例如它可能会像C:\Users\username\seaborn-data在 Windows 上一样出现。

将文件下载https://raw.githubusercontent.com/mwaskom/seaborn-data/master/tips.csv到该文件夹​​。最后，使用“缓存”选项

sns.load_dataset("tips", cache=True)

或者将文件下载到任何其他文件夹。使用该文件夹的路径名作为data_home参数

sns.load_dataset(name, cache=True, data_home="path/to/folder")
