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

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"
