我目前正在在scikit-learn
没有 root 访问权限的计算机上安装 Python 包。在 Fedora 14 上使用 Python 2.7。
pip 没有安装,所以我使用的是easy_install:
easy_install --prefix=$HOME/.local -U scikit-learn
安装过程抱怨没有安装 BLAS。我过去曾尝试安装 scipy,但在查找和安装 Atlas/BLAS 时遇到了麻烦。从那以后,我检查了 numpy 对 Atlas 没有问题:
>>> import numpy as np
>>> np.__config__.show()
atlas_threads_info:
libraries = ['lapack', 'ptf77blas', 'ptcblas', 'atlas']
library_dirs = ['/usr/lib/atlas']
language = f77
include_dirs = ['/usr/include']
blas_opt_info:
libraries = ['ptf77blas', 'ptcblas', 'atlas']
library_dirs = ['/usr/lib/atlas']
define_macros = [('ATLAS_INFO', '"\\"3.8.3\\""')]
language = c
include_dirs = ['/usr/include']
atlas_blas_threads_info:
libraries = ['ptf77blas', 'ptcblas', 'atlas']
library_dirs = ['/usr/lib/atlas']
language = c
include_dirs = ['/usr/include']
lapack_opt_info:
libraries = ['lapack', 'ptf77blas', 'ptcblas', 'atlas']
library_dirs = ['/usr/lib/atlas']
define_macros = [('ATLAS_INFO', '"\\"3.8.3\\""')]
language = f77
include_dirs = ['/usr/include']
lapack_mkl_info:
NOT AVAILABLE
blas_mkl_info:
NOT AVAILABLE
mkl_info:
NOT AVAILABLE
/usr/lib/atlas
存在,并且包含 .so 文件。
这是easy_install存在的错误:

/usr/lib/python2.7/site-packages/numpy/distutils/misc_util.py:248: RuntimeWarning: Parent module 'numpy.distutils' not found while handling absolute import
from numpy.distutils import log
以及安装早期的警告:
/usr/lib/python2.7/site-packages/numpy/distutils/system_info.py:1392: UserWarning:
Atlas (http://math-atlas.sourceforge.net/) libraries not found.
Directories to search for the libraries can be specified in the
numpy/distutils/site.cfg file (section [atlas]) or by setting
the ATLAS environment variable.
所以安装过程似乎找不到 numpy 或 Atlas。我如何告诉它在哪里可以找到这些?
