通过URL链接数据集

# Get the IRIS dataset
url = "https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data"
data = pd.read_csv(url, names=['sepal length', 'sepal width', 'petal length', 'petal width', 'target'])
但是显示报错
1
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)>
然后通过以下方式解决，全局取消证书验证

import ssl
ssl._create_default_https_context = ssl._create_unverified_context
