在执行教程时使用sklearn遇到ImportError

问题描述

我正在尝试遵循sklearn提供的机器学习101教程，但我一直遇到错误.

Hi I'm trying to follow the machine learning 101 tutorial provided by sklearn, and I keep running into an error.

我从这里下载的sklearn版本最多: https://github.com/scikit -learn/scikit-learn

I have the most the sklearn version downloaded from here: https://github.com/scikit-learn/scikit-learn

我运行Windows

I run Windows

python:2.7.5(32位)

python: 2.7.5 (32bit)

scipy:.12

scipy: .12

numpy:1.7.0

numpy: 1.7.0

我跑步时

from sklearn.linear_model import LinearRegression
model = LinearRegression()

我知道

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

ImportError: No module named cd_fast

并基于此: https://github.com/scikit-learn /scikit-learn/issues/1202

blas可能是错误的?但这是秘密的，我之前有这个问题，但是我只是更新了秘密，应该没问题.

It might be an error with blas? But that's in scipy, and I had problems with that earlier, but I just updated scipy and it should be fine.

请帮助！预先感谢

推荐答案

您忘了编译.在源目录或python setup.py build_ext --inplace中运行python setup.py install，或获取二进制发行版.

You forgot to compile. Run python setup.py install in the source directory, or python setup.py build_ext --inplace, or grab a binary distribution.

(许多scikit-learn实际上是用Cython，C或C ++实现的.您需要C和C ++编译器才能从源代码安装它.)

(Much of scikit-learn is actually implemented in Cython, C or C++. You need C and C++ compilers to install it from source.)
