我使用 pip 成功安装了 scikit-flow，但不知何故，当我导入和使用它时它不起作用

Question

前几天我已经安装了scikitslearn，我尝试执行的代码如下。

import skflow
from sklearn import datasets, metrics
iris = datasets.load_iris()
classifier = skflow.TensorFlowLinearClassifier(n_classes=3)
classifier.fit(iris.data, iris.target)
score = metrics.accuracy_score(classifier.predict(iris.data),     iris.target)
print("Accuracy: %f" % score)

上面的代码是我在Githubgist页面上找到的。结果是

ImportError                               Traceback (most recent call last)

我最近才开始编码，所以我根本无法处理这个问题。。这里的"错误架构"是什么意思？？希望有人回答这个问题。

看起来您安装了错误版本的tensorflow。在这种情况下，错误的体系结构可能意味着您在OS X上安装了linux版本的TF。

我建议卸载tensorflow和skflow，然后运行以下命令（对于带有Python2.7的OS X）：

sudo easy_install --upgrade six
sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.8.0rc0-py2-none-any.whl

Skflow现在是TensorFlow的一部分，因此您可以通过导入import tensorflow.contrib.learn as skflow而不是import skflow来使用。
