Question

我试图使用sclearn.decomposition，但我得到了以下错误：

Python 2.7.5 (default, Mar  9 2014, 22:15:05)

ValueError: numpy.dtype has the wrong size, try recompiling

我尝试使用pip卸载并安装所有软件包。不知道还有什么可以尝试任何建议吗？

更新

结果我以某种方式安装了旧版本的numpy / scipy我手动删除它们但现在我得到以下运行时错误：

Answer 1

二进制文件似乎存在问题。我和熊猫有同样的错误，我通过卸载numpy和pandas并再次安装它来修复它。

pip uninstall numpy
pip uninstall pandas
pip install pandas==0.13.1

请注意，安装pandas还会安装它的依赖项，例如numpy。

你的numpy和scipy版本似乎也很旧。尝试更新它们。

ValueError：numpy.dtype的大小错误，导入分解
