Python 2.7のnumpy問題 - numpy.dtypeのサイズが間違っています

Question

これまでに同様の問題を抱えていた人がいらっしゃいましたか？ Mac OSXでのPython 2.7の使用再インストールしようとしたとき

import numpy as np 
import matplotlib.pyplot as plt 
from sklearn import linear_model, datasets 

# import some data to play with 
iris = datasets.load_iris() 
X = iris.data[:, :2] # we only take the first two features. 
Y = iris.target 

h = .02 # step size in the mesh 

logreg = linear_model.LogisticRegression(C=1e5) 

# we create an instance of Neighbours Classifier and fit the data. 
logreg.fit(X, Y) 

Traceback (most recent call last): 
    File "/Users/foo/Downloads/PycharmProjects/testLogisticRegressionSimple.py", line 23, in <module> 
    from sklearn import linear_model, datasets

ValueError: numpy.dtype has the wrong size, try recompiling 

編集1は、あなたのコードは、それが環境エラーだこれ示唆して、私のために正常に動作し、コマンドとエラーメッセージが表示され、ここで、エラーで

sudo /usr/local/bin/pip install --upgrade --force-reinstall numpy sklearn

You are using pip version 8.1.1, however version 8.1.2 is available. 
You should consider upgrading via the 'pip install --upgrade pip' command.

sudo pip install --upgrade --force-reinstall numpy sklearnを実行して、そのトリックがあるかどうかを確認してください。

あなたが自作経由でインストールした場合：brew install --force numpy（ないsklearn自作パッケージはありません）

あなたはMacPortsの経由でインストールした場合：

port -f uninstall py27-numpy 
port install py27-numpy 

（しかし、あなたが自作やMacPortsのいずれかを経由してインストールした場合、私は（アンインストールをお勧めしますport -f uninstall py27-numpy || brew uninstall numpy）、代わりにpip経由でインストールしてください
