本文档详细介绍了Python科学计算中常用包的安装步骤及注意事项，包括pyparsing、dateutil、scipy、numpy等，并提供了针对特定错误的解决方案。

依赖包：

pyparsing、dateutil、scipy、numpy、libpng 1.2 (or later)、`freetype` 1.4 (or later)

安装pyparsing：

# pip install pyparsing

安装numpy：

# pip install numpy

安装dateutil：

# pip install Python-dateutil

安装scipy：

# pip install scipy

待测：sudo yum -y install gcc gcc-c++ numpy python-devel scipy(不过这些包都装好了）

报错：

# pip install scipy

解决方法：

# pip --default-timeout=100 install django

重新安装scipy

各个安装包版本：

nose-1.3.1

lapack-3.5.0

atlas-3.10.1

scipy-0.11.0

numpy-1.6.2

依赖关系：scipy的安装需要依赖于numpy、lapack、atlas（后两者都是线性代数工具包，不清楚的自行google），而numpy和sci的测试程序的运行又依赖于nose，因此，整个安装过程必须要按顺序执行的，否则是无法执行下去的。

安装nose：

# pip install nose

安装lapack：

#yum install lapack lapack-devel blas blas-devel

更新pip
# pip install --upgrade pip

安装scipy：

# pip install scipy

安装matplotlib：

# pip install matplotlib

报错：

安装freetype：

依赖freetype-devel

# yum install　freetype-devel

# yum install　freetype

安装matplotlib：

# cd matplotlib-1.5.1

# python setup.py install

测试：
