ValueError：numpy.dtype 的大小错误，带有导入分解[重复]

Question

我正在尝试使用 sclearn.decomposition，但出现以下错误：

Python 2.7.5 (default, Mar  9 2014, 22:15:05) 
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin

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

我尝试使用 pip 卸载和安装所有软件包。不确定还有什么可以尝试的建议？

更新：

结果我安装了旧版本的 numpy/scipy 我手动删除了它们，但现在我收到以下运行时错误：

Answer 1

二进制文件似乎有问题。我在使用 pandas 时遇到了同样的错误，我通过卸载 numpy 和 pandas 并再次安装来修复它。

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

请注意，安装 pandas 也会安装它的依赖项，例如 numpy。

您的 numpy 和 scipy 版本似乎也很旧。尝试更新它们。
