python - AttributeError:模块“scipy”在sklearn/utils/fixes.py中没有属性“sparse”

Question

我已经更新了sklearn，scipy（以前一切正常。）。当前版本：

python: 3.6.8
scikit-learn 0.20.3
numpy: 1.16.2
scipy: 1.2.1

结果，该错误开始发生：

  File "....projects/Test.py", line 8, in <module>
    from sklearn import datasets

  File "C:\ProgramData\Anaconda3\lib\site-packages\sklearn\__init__.py", line 64, in <module>
    from .base import clone

  File "C:\ProgramData\Anaconda3\lib\site-packages\sklearn\base.py", line 14, in <module>
    from .utils.fixes import signature

  File "C:\ProgramData\Anaconda3\lib\site-packages\sklearn\utils\__init__.py", line 16, in <module>
    from .fixes import _Sequence as Sequence

  File "C:\ProgramData\Anaconda3\lib\site-packages\sklearn\utils\fixes.py", line 20, in <module>
    import scipy.sparse as sp

AttributeError: module 'scipy' has no attribute 'sparse'

我试图重新安装sklearn，scipy，但没有帮助。

无效的示例代码：

from sklearn import datasets

iris = datasets.load_iris()

Answer 1

重新安装scikit-learn，scipy和numpy后，问题已解决
