Sphinx无法导入公共Python3包

Question

我是Sphinx文档的新手，正在尝试使用它为python模块生成autodocs。我能够部分地生成它们，并且会出现以下错误：

/home/yash/Music/MailingListParser/bDocs/analysis.author.rst:17: WARNING: autodoc: failed to import module 'analysis.author.curve_fitting'; the following exception was raised:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/sphinx/ext/autodoc.py", line 560, in import_object
    __import__(self.modname)
  File "/home/yash/Music/MailingListParser/lib/analysis/author/curve_fitting.py", line 3, in <module>
    from sklearn.metrics import mean_squared_error
ModuleNotFoundError: No module named 'sklearn'

类似的还有plotly，sklearn等

我用的是Python3和狮身人面像1.5.6。在
