scikit-learn安装失败/找不到numpy/缺少numpy标头 [英] scikit-learn install failure / numpy not found / missing numpy headers
问题描述
当我尝试通过以下方式在Suse(openSuse 12.2 x86_64)服务器上安装scikit-learn时:
When i try to install scikit-learn on a Suse (openSuse 12.2 x86_64) server via:
pip install -U scikit-learn
我收到以下错误:
(....)
compile options: '-I/usr/lib64/python2.7/site-packages/numpy/core/include -Isklearn/svm/src/libsvm -I/usr/lib64/python2.7/site-packages/numpy/core/include -I/usr/include/python2.7 -c'
gcc: sklearn/svm/libsvm.c
sklearn/svm/libsvm.c:303:31: fatal error: numpy/arrayobject.h: No such file or directory
compilation terminated.
sklearn/svm/libsvm.c:303:31: fatal error: numpy/arrayobject.h: No such file or directory
compilation terminated.
我已经尝试过:
-将gcc安装到最新版本
通过easy_install从下载的zip安装scikit(以避免旧的回购协议)
-卸载并重新安装numpy(通过pip)
-installing gcc to the latest version
-installing scikit from a downloaded zip, over easy_install (to avoid old repos)
-uninstalling and reinstalling numpy (over pip)
当我尝试安装scipy时(这是numpy的要求)，我得到了类似的错误:
When i try to install scipy (which is a requirement of numpy) i get a similar Error:
adding 'build/src.linux-x86_64-2.7/fortranobject.c' to sources.
adding 'build/src.linux-x86_64-2.7' to include_dirs.
error: file '/usr/lib64/python2.7/site-packages/numpy/f2py/src/fortranobject.c' does not exist
显然，"site-packages/numpy/core/include"中的所有numpy标头都丢失了.我已经用pip重新安装了numpy，没有任何问题，但是标题仍然丢失.
Apparently all the numpy headers in "site-packages/numpy/core/include" are missing. I already reinstalled numpy with pip without any Problems but the headers are still missing.
推荐答案
好，当我使用pip安装numpy或通常缺少所有包含标头时.
Ok when i installed numpy with pip or normally all the include header were missing.
要解决此问题，我安装了包含标头的软件包"python-numpy-devel" (带有zypper，愚蠢的suse软件包名称...).
To fix this i installed the package "python-numpy-devel" (with zypper, stupid suse package names...) which contains the headers.
之后，标题就在那里，其余的都起作用了.
After that the headers are there and the rest works.
