Scikit安裝詢問SciPy的，即使它是安裝

我試圖通過運行安裝Scikit：Scikit安裝詢問SciPy的，即使它是安裝

pip install scikit-learn

當我運行它，我得到這個消息：

Collecting scikit-learn

    scikit-learn requires SciPy >= 0.9.

這似乎問我安裝SciPy的，但是我已經安裝SciPy的，而事實上，如果我跑

pip install scipy

我得到

Requirement already satisfied: scipy in c:\python36\lib\site-packages 
Requirement already satisfied: numpy>=1.8.2 in c:\python36\lib\site-packages (from scipy)

你安裝了什麼版本的scipy？ –

我有版本0.19 32位 – Nadni

你的機器上已經安裝了numpy和mkl嗎？然後你會嘗試安裝scipy。獲得Scipy生態系統工作的最簡單方法可能是收集所有那些包：http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy – tagoma

你安裝顯示了這個：from numpy._distributor_init import NUMPY_MKL # requires numpy+mklImportError: cannot import name 'NUMPY_MKL'

所以，你需要做幾件事。得到正確的SciPy的：http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy

得到正確的NumPy的：http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

得到正確的SciKit瞭解：http://www.lfd.uci.edu/~gohlke/pythonlibs/#sci-kitlearn

現在做各pip uninstall的其他包。然後在您提供的鏈接處下載pip install輪圈 - NumPy 1st，SciPy 2nd，然後是Ski-kitlearn last。那應該可以解決你的問題。請注意，根據您是否安裝了32位或64位Python，您正在使用cp36‑cp36m‑win32.whl或cp36‑cp36m‑win_amd64.whl下載文件。
