git仓库瘦身

参考GitHub官网: https://help.github.com/articles/removing-sensitive-data-from-a-repository
 # 查看对象文件记录
git rev-list --objects --all 
例如, 我的jekyll博客代码库提交了大量mp3文件, 使用下面命令清除后代码库由233M缩小为1.3M, 提交到GitHub部署博客轻快飞速
# 清除垃圾文件(大量无用的mp3文件)
git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch *.mp3' --prune-empty --tag-name-filter cat -- --all

# 提交到远程仓库(如GitHub, 我再次从git clone GitHub代码库会变小为1.3M)
git push origin --force --all

# 必须回收垃圾,本地仓库才变小
git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin    
git reflog expire --expire=now --all
git gc --prune=now

rm -rf .git/refs/original
git reflog expire --expire=now --all
git gc --prune=now
git gc --aggressive --prune=now

python2的安装方法：

pip install opencv-python

python3的安装方法：

网上很多人都是用源码编译的方式。也可通过pip方式安装。

pip3 install opencv-python
sudo apt install libatlas3-base libjasper1 libgst7 python3-gst-1.0 libqtgui4 libqt4-test

其实使用python3后，再import cv2从错误信息中就能知道缺少什么库，再使用sudo apt-cache search相关包就能查询到名称，最后使用apt安装即可。

解决树莓派采样率16k报错

确保pulseaudio服务器依旧在工作 sudo apt-get install pulseaudio

添加自启动 vim /etc/systemd/system/pulseaudio.service


[Unit]
Description=PulseAudio Sound System
Before=sound.target

[Service] BusName=org.pulseaudio.Server ExecStart=/usr/bin/pulseaudio Restart=always

[Install] WantedBy=session.target


- 然后重启应该就能正常运行了
