conda virtualenv

以前玩深度学习一直是用的theano和keras，做为谷粉不能不试一下大热的TensorFlow。首先安装起来。

TensorFlow的安装指南非常详细，我是python的anaconda环境，所以直接先创建一个新环境，创建前先更新一下conda
conda update conda
conda update anaconda
看一下目前计算机上有哪些环境
conda info --env
目前只有root环境，所以新建一个专门为TensorFlow的环境，并将root中的包克隆过来
conda create --name tensorflow --clone root
激活使用环境
source activate tensorflow
退出环境
source deactivate

使用pip来安装
pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.8.0-py2-none-any.whl

然后我们可以使用jupyter notebook来启动，下面是两个最简单的示例。

sudo gdebi netease-cloud-music_1.0.0_amd64_ubuntu16.04.deb

huozhe
apt-get -f install

GibbsLDA++ 使用记录

之前在centos下编译成功了，但是现在用的是ubuntu 16.04报错了

错误如下：

在http://blog.sciencenet.cn/blog-425672-654209.html找到答案，解决办法

解决方法：

1）. 在src/utill.cpp 文件头加入：

#include<stdio.h> #include<stdlib.h>

2）. 在src/utill.h 文件头加入：

#include<stdlib.h>

3）. 在src/lda.cp 文件头加入：

#include<stdio.h>

4）. 重新make

http://dev.mysql.com/doc/refman/5.6/en/load-data.html shows the syntax. The clause naming columns goes after the IGNORE clause.

git push origin v0.1

git tag -a v0.1 -m "Relase version v0.1"

git push origin v0.1

Git 中的tag指向一次commit的id，通常用来给开发分支做一个标记，如标记一个版本号。

打标签

git tag -a v1.01 -m "Relase version 1.01"

注解：git tag 是打标签的命令，-a 是添加标签，其后要跟新标签号，-m 及后面的字符串是对该标签的注释。

提交标签到远程仓库
git push origin -tags
注解：就像git push origin master 把本地修改提交到远程仓库一样，-tags可以把本地的打的标签全部提交到远程仓库。
删除标签
git tag -d v1.01
注解：-d 表示删除，后面跟要删除的tag名字
删除远程标签
git push origin :refs/tags/v1.01
注解：就像git push origin :branch_1 可以删除远程仓库的分支branch_1一样， 冒号前为空表示删除远程仓库的tag。
查看标签
git tag
或者

git tag -l
