Linux 64位下一键安装scipy等科学计算环境

采用scipy.org的各种方法试过了，安装还是失败。找到了一键式安装包Anaconda，基本python要用到的库都齐了，而且还可以选择安装到其他目录下。

Anaconda is an easy-to-install free package manager, environment manager, Pythondistribution, and collection of over 720 open source packages offering free community support.

安装这个自动安装下面的机器学习算法包：

sciki-learn

Simple and efficient tools for data mining and data analysis
Accessible to everybody, and reusable in various contexts
Built on NumPy, SciPy, and matplotlib
Open source, commercially usable - BSD license

http://scikit-learn.org/stable/

1 安装 anaconda2

我选择python2.7的Linux安装包，安装的目录是:

/opt/anaconda2

一直使用的是python2.7.x，于是下载下面的包：

$ nohup wget -c http://repo.continuum.io/archive/Anaconda2-4.0.0-Linux-x86_64.sh &

按国内的网速，基本下一夜吧！也可以到我的FTP上下载：

$ wget ftp://pub:pub@pepstack.com/tarball/Anaconda2-4.0.0-Linux-x86_64.tgz

下载后解压安装。不解释。

# bash Anaconda2-4.0.0-Linux-x86_64.sh

安装完毕后执行一下：

# cd /opt/anaconda2/bin# ./python

输出：

Python 2.7.11 |Anaconda 4.0.0 (64-bit)| (default, Dec 6 2015, 18:08:32)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2

>>> import scipy
>>> import numpy
>>> import matplotlib

>>> import sklearn

>>> import mysql.connector
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named mysql.connector
>>> import theano
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named theano

./pip install --upgrade pip
./pip install theano

2 解决mysql.connector错误的问题

./pip install $pkg 查看哪些包$pkg可用：

https://docs.continuum.io/anaconda/pkg-docs

./pip install mysql-connector-python

失败！

./pip install mysql-python

失败！

于是手工安装：

# cd /opt/anaconda2/pkgs# wget ftp://pub:pub@pepstack.com/tarball/mysql-connector-python-2.1.1.tar.gz# tar -zxf mysql-connector-python-2.1.1.tar.gz# cd mysql-connector-python-2.1.1# ../../bin/python setup.py build# ../../bin/python setup.py install# cd /opt/anaconda2/bin# python -c "import mysql.connector"

成功！

3 安装 python-inotify

# cd /opt/anaconda2/pkgs# wget --no-check-certificate https://pypi.python.org/packages/source/p/pathlib/pathlib-1.0.1.tar.gz# wget ftp://pub:pub@pepstack.com/prepare/JanKanis-python-inotify.tar.gz

（解压略）

# cd /opt/anaconda2/pkgs/pathlib-1.0.1# ../../bin/python setup.py build# ../../bin/python setup.py install# cd /opt/anaconda2/pkgs/JanKanis-python-inotify# ../../bin/python setup.py build# ../../bin/python setup.py install# cd /opt/anaconda2/bin# python -c "import inotify"

成功！

4 安装 google tensor

TensorFlow is an Open Source Software Library for Machine Intelligence

下载CPU版本：

# wget http://ci.tensorflow.org/view/Nightly/job/nightly-matrix-cpu/TF_BUILD_CONTAINER_TYPE=CPU,TF_BUILD_IS_OPT=OPT,TF_BUILD_IS_PIP=PIP,TF_BUILD_PYTHON_VERSION=PYTHON2,label=cpu-slave/lastSuccessfulBuild/artifact/pip_test/whl/tensorflow-0.8.0-cp27-none-linux_x86_64.whl

或者：

# wget ftp://pub:pub@pepstack.com/tarball/tensorflow-0.8.0-cp27-none-linux_x86_64.whl

然后安装：

$ sudo /opt/anaconda2/bin/pip install /path/to/tensorflow-0.8.0-cp27-none-linux_x86_64.whl

测试：

$ /opt/anaconda2/bin/python -c "import tensorflow"
