我正在尝试安装numpy==1.10.2,scipy并matplotlib在服务器上基于opensuse.我已经从源头安装numpy了virtualenv(我也尝试过pip - 当然也是同样的结果).现在,当我尝试numpy在python控制台中导入时,我收到以下错误:
ImportError: /home/user/.virtualenvs/project/lib/python2.7/site-packages/numpy/core/multiarray.so: undefined symbol: cblas_sgemm
注意:我不是这台服务器的超级用户.
编辑:

SOLLUTION
问题出在ATLAS lib上.根据@ali_m建议我numpy从源代码安装OpenBLAS而不是ATLAS.这里链接到如何使用BLAS安装numpy的说明.
