Question

我尝试使用sklearn，但得到错误湖：

| Error     from sklearn.ensemble import RandomForestClassifier
    | Error   File "/Library/Python/2.7/site-packages/sklearn/ensemble/__init__.py", line 12, in <module>
    | Error     from .bagging import BaggingClassifier
    | Error   File "/Library/Python/2.7/site-packages/sklearn/ensemble/bagging.py", line 20, in <module>
    | Error     from ..linear_model import LogisticRegression
    | Error   File "/Library/Python/2.7/site-packages/sklearn/linear_model/__init__.py", line 23, in <module>
    | Error     from .ridge import (Ridge, RidgeCV, RidgeClassifier, RidgeClassifierCV,
    | Error   File "/Library/Python/2.7/site-packages/sklearn/linear_model/ridge.py", line 21, in <module>
    | Error     from .sag import sag_solver
    | Error   File "/Library/Python/2.7/site-packages/sklearn/linear_model/sag.py", line 14, in <module>
    | Error     from .sag_fast import sag, get_max_squared_sum
    | Error ImportError: cannot import name get_max_squared_sum

我使用的是python2.7 mac OS。在github下载scikit-learn-master，然后运行sudo python setup.py install

我得到的清单太长了，所以我只放了一个我认为可能很重要的切片

running install
running build

Answer 1

从文档中他们提到这些先决条件在安装scikit之前安装它们

Python (>= 2.6 or >= 3.3),
NumPy (>= 1.6.1),
SciPy (>= 0.9).

然后运行：

pip install -U scikit-learn

实现sklearn但得到错误
