SciKit-Learn Python軟件包有錯誤

下面是當我嘗試運行我的Python代碼時所遇到的錯誤代碼。這是我的安裝問題嗎？我安裝了python 64-bit 3.6.0，我確定我安裝了64位版本的sci-kit。我也有numpy，scipy作爲先決條件安裝。SciKit-Learn Python軟件包有錯誤

因爲你的代碼的第一行產生錯誤，你不應該發表任何更多。請參閱https://stackoverflow.com/help/mcve。 –

你可能有numpy的1.12測試版（1.12.0b1）這就是爲什麼它抱怨STR和INT之間的比較（0B1和0）。

fixes.py的最後一個版本解決這個問題： https://github.com/scikit-learn/scikit-learn/commit/1f278e1c231e6b9b3cf813377819e25e87b6c8b6

謝謝，我會看看它是否有效！ –

作品！感謝這件事！我對python/kaggle完全陌生，所以我不知道。 –

它的工作原理！我從http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn py3.6 win32安裝了sklearn。希望它能儘快修復whl文件。 –
