在 sklearn 中导入 svm 时“无法导入名称 check_arrays”

Question

Sklearn 在导入 sklearn.svm 时抛出错误"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check_array取代。似乎旧check_arrays被一些称为表单 svm 的代码使用，这是 sklearn.svm 模块中的错误吗？

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，bicluster_metrics.py 而是在 sklearn/metrics/cluster 中 （https://github.com/scikit-learn/scikit-learn/tree/0.17.1/sklearn/metrics/cluster）。

那只是一个不干净的安装。希望这对某人有所帮助！
