在Red Hat上安装SciPy

Question

I am trying to install the SciPy package on Red Hat Enterprise Linux Server release 6.3. However, it is failing.

The version of Python I am using is 2.6, however it seems to require 2.4. Is there another version of SciPy that is compatible with 2.6? If 2.4 is required, any suggestions on how to get that? I followed the directions on the python webpage but they seem to be out of date. It also requires f2py, which I am unsure of how to get.

Any suggestions for easier installation? I had been following the instructions here .

Thanks!

Answer 1

Enable the EPEL repository: https://fedoraproject.org/wiki/EPEL

After that, just "yum install scipy"

Answer 2

我能够通过下载最新版本的NumPy（从源代码构建并安装该版本，因为Red Hat软件包管理器上的版本已经过时）来解决此问题，然后安装scipy（通过setup.py scipy文件我已下载）。

Answer 3

A problem I ran into when installing SciPy from setup.py on RHEL 5 was undefined _gfortran symbols.

I found out this is due to a mismatch in the FORTRAN compiler used -- I had used the gfortran compiler to build the ATLAS/BLAS libraries but was using the g77 compiler to build SciPy

If you have this problem, fix it by specifying the FORTRAN version to use with setup. In my case, to use the gfortran compiler:

python setup.py build --fcompiler=gnu95 --force

The --force flag was necessary to correct the build with the wrong compiler.

To list your FORTRAN compilers available use:

python setup.py build --help-fcompiler

After that,

python setup.py install

as usual.
