python - SSL：在 Windows 上运行 python 程序时出现 CERTIFICATE_VERIFY_FAILED 错误

问题描述

我试图运行脚本并收到此错误（Python 3.6.5，Windows 10）。请注意，我已经尝试了几种解决方案，例如在 python 脚本中添加一些代码行。我也尝试从 Ubuntu 系统运行相同的脚本，但遇到了类似的错误。

导致此问题的代码行：

data = pd.read_csv(os.path.join(_fetch_file(
    'https://www.research.ibm.com/haifa/dept/vst/files/IBM_Debater_(R)_TR9856.v2.zip',
    'similarity', uncompress=True, verbose=0),
    'IBM_Debater_(R)_TR9856.v0.2', 'TermRelatednessResults.csv'), encoding="iso-8859-1")

完整日志：
