mac机器学习开发环境部署及helloworld

一、下载并安装Anaconda2.7
https://repo.anaconda.com/archive/Anaconda2-5.2.0-MacOSX-x86_64.pkg
路径：/Users/shijun/anaconda2

二、运行Anaconda Navigator -> Environments -> base(root) -> 点击三角图标 -> Open Terminal

遇到问题：/Users/.anaconda/navigator/a.tool: line 1: activate: No such file or directory

解决问题：指定ANACONDA_HOME路径

export IPFS_HOME=/Users/shijun/Desktop/openSourceProject/go-ipfs

export SONAR_HOME=/Users/shijun/Desktop/openSourceProject/sonarqube-7.1

export ANACONDA_HOME=/Users/shijun/anaconda2

export PATH=$PATH:$IPFS_HOME:$SONAR_HOME:$ANACONDA_HOME/bin

三、激活tensorflow

接着第二步后面执行conda create -n tensorflow python=2.7

激活tensorflow命令：source activate tensorflow

关闭tensorflow命令：(tensorflow)$ source deactivate

四、使用pip安装TensorFlow

pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.11.0rc0-py2-none-any.whl
五、测试python代码

$ python

>>> import tensorflow as tf

>>> print(tf.__version__)

# 0.11.0rc0

六、下载pycharm
https://www.jetbrains.com/pycharm/download/#section=mac
七、注意事项

1、如果报错找不到main，因为Run/Debug Configurations中的配置, Script path必须指定文件，比如/Users/shijun/Desktop/PycharmProjects/untitled2/helloworld.py

2、找不到CAL.PyCAL的问题

# -*- coding:utf8 -*-

from CAL.PyCAL import *

报错：ImportError: No module named CAL.PyCAL

$ sudo pip install CAL后依然报错，使用$ pip list能够找到CAL

查找CAL路径

$ pip show CAL

Name: CAL

Version: 2.2.6
