导入sklearn中的svm时无法导入名称check_arrays

Question

导入sklearn.svm时，Sklearn抛出错误“无法导入名称check_arrays”。

我已经搜索了这个问题，另一个问题表明check_arrays已被替换为check_array。似乎旧的check_arrays被一些称为form svm的代码所使用，这是sklearn.svm模块中的一个错误吗？

刚刚更新到版本0.17.1。

好的，所以问题解决了。 Sklearn 0.17.1没有目录bicluster，而bicluster_metrics.py在sklearn/metrics/cluster中（https://github.com/scikit-learn/scikit-learn/tree/0.17.1/sklearn/metrics/cluster）。

这只是一个不洁净的安装。希望这可以帮助别人！
