ImportError in importing from sklearn: cannot import name check_build
>>> from sklearn import preprocessing, metrics, cross_validationTraceback (most recent call last): File "<pyshell#6>", line 1, in <module> from sklearn import preprocessing, metrics, cross_validation File "D:\Python27\lib\site-packages\sklearn\__init__.py", line 31, in <module> from . import __check_buildImportError: cannot import name __check_build>>> ================================ RESTART ================================>>> from sklearn import preprocessing, metrics, cross_validation>>> So, simply try to restart the shell!
My solution for Python 3.6.5 64-bit Windows 10:
pip uninstall sklearnpip uninstall scikit-learnpip install sklearn
No need to restart command-line but you can do this if you want.It took me one day to fix this bug. Hope this help.
