ImportError：无法从部分初始化模块'sklearn'导入名称check_build

Question

尝试从sklearn导入时出现以下错误

from pandas import read_csv
from numpy import mean
from matplotlib import pyplot
from sklearn.metrics import mean_squared_error

这是错误：

ImportError                               Traceback (most recent call last)
<ipython-input-1-c57768f466c0> in <module>
      2 from numpy import mean
      3 from matplotlib import pyplot
----> 4 from sklearn.metrics import mean_squared_error

ImportError: cannot import name '__check_build' from partially initialized module 'sklearn' (most likely due to a circular import) (C:\Users\user\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\sklearn\__init__.py)

我遇到了同样的问题，但是我设法解决了。.值得您花时间尝试： 请按照顺序进行。 在CMD中，

1. • a）pip卸载numpy

   • b）pip卸载scipy

   • c）pip卸载matplotlib

   • d）pip卸载sklearn

   • e）pip卸载scikit-learn

然后

1. • a）点安装numpy
   • b）点安装scipy
   • c）pip安装matplotlib
   • d）点安装sklearn
   • e）点安装scikit-learn

按照1a）至1e），然后按照2a）至2e）。
