Python TypeError:uuu init_uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu；决策函数(u形)'；

python scikit-learn

Python TypeError:uuu init_uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu；决策函数(u形)'；,python,scikit-learn,svm,Python,Scikit Learn,Svm,我尝试创建一个SVM分类器，如下所示： # Create a SVM Classifier model = SVC(C=1.0, cache_size=200, class_weight=None, coef0=0.0, decision_function_shape=None, degree=3, gamma='auto', kernel='linear', max_iter=-1, probability=True, random_state=

我尝试创建一个SVM分类器，如下所示：

# Create a SVM Classifier
model = SVC(C=1.0, cache_size=200, class_weight=None, coef0=0.0,
            decision_function_shape=None, degree=3, gamma='auto', kernel='linear',
            max_iter=-1, probability=True, random_state=None, shrinking=True,
            tol=0.001, verbose=False
            )
（使用Python 2.7）

但是得到这个错误--

TypeError:init（）获取了意外的关键字参数 “决策函数形状”

关于这一点的任何想法都将非常有用。干杯

我确实将我的
sklearn
升级到了
版本0.18
。早些时候它是
0.16.1
，正如@coryKramer所建议的--decision\u function\u shape参数仅在版本0.17+中添加。

所以我按照他的建议升级了，现在一切都很好

同时，这里介绍了如何在Windows中使用pip从cmd升级

pip install scikit-learn==0.18 --force-reinstall
您可以省去它，因为您使用的是默认的
None
，您安装了哪个版本的
sklearn
？看起来
decision\u function\u shape
参数仅在0.17+版本中添加。例如，这里是0.16中的文档，它是0.16.1。我试图安装更新，但它一直在说-没有找到与升级匹配的发行版。
