Raspberrypi 2 Install or upgrade Python3.6
李魔佛 发表了文章 • 0 个评论 • 3713 次浏览 • 2019-07-21 14:55
Raspberrypi has python2. 7 and python3.4, but i want to upgrade to python3.6+.
Python3.6 support some new feature such as print(f'{name}') and x=1_000_242_200 expression.
How to upgrade ?
$ wget https://www.python.org/ftp/pyt ... 1.tgz $ tar zxvf Python-3.6.1.tgz $ cd Python-3.6.1
then run command:
$ sudo ./configure && sudo make && sudo make install
wait for about 20mins (low perf of raspberrypi :( )
then you run command:
python3
it will using the new python3.6 version:
Python 3.6.1 (default, Jul 21 2019, 14:26:28)
[GCC 4.9.2] on linux
Type "help", "copyright", "credits" or "license" for more information.

mongo服务启动失败: ERROR: mmap private failed with out of memory

sudo mongod --fork --dbpath /home/pi/mongo/db/ --smallfiles --journal --logpath /home/pi/mongo/log.txt
突然今天发现mongo的服务连不上,看log发现mongo在启动后马上关闭了,提示的错误是在加载一个大的数据文件的时候提示内存不足(坑爹的,树莓派自身内存才1GB,无法扩容)。

因为使用ubuntu连接本机的mongd server,没有出现这个问题。 所以问题应该处在版本上。

树莓派中使用matplotlib出错 TypeError: constructor returned NULL

上面的代码是在树莓派上运行出错的,而在本地的ubuntu上正常运行没问题。
后面查了下资料,原因是我用了ssh登录到树莓派,所以X11的模块没有被正常加载。
按照以下方法就可以解决问题了:
在代码中添加以下这一句:
matplotlib.use("Pdf")
而且这一句要在import matplotlib.pyplot as plt这句前面添加。

树莓派时间修改为中国本地时间
李魔佛 发表了文章 • 0 个评论 • 7187 次浏览 • 2018-03-05 17:23
很容易看出,和中国时间相差了八个小时。这是由于树莓派默认显示的是UTC,也就是国际时区的时间。
解决方案如下:
首先,我们要了解一个东东,它的名字叫做NTP。
NTP(Network Time Protocol,网络时间协议)是用来使网络中的各个计算机时间同步的一种协议。
第一步:安装NTP,输入指令“sudo apt-get install ntpdate ”。
第二步:启用NTP,输入指令“sudo timedatectl set-ntp true”。
第三步:修改本地时区,输入指令“sudo dpkg-reconfigure tzdata”。
在这一步中,我选的是“asia/shanghai”时区。
再次输入“date”指令:
可见已经顺利变成本地时间CST。

树莓派上安装redis-server 亲测
李魔佛 发表了文章 • 0 个评论 • 6971 次浏览 • 2017-07-17 23:47
1. 下载源码压缩包:
官方网址: https://redis.io/download
下载下来的格式为tar.gz
通过命令行解压: tar xvfz xxxxxx.tar.gz
2. 解压后进入 redis-4.0.0的目录,然后执行命令: make
3. 等待源码编译(树莓派上有点久), 见到这一行:Hint: It's a good idea to run 'make test' ;)
说明你安装成功了
4. 编译成功后, 记得运行命令 sudo src/redis-server
来启动redis server。

dataframe 将某列字符类型转为日期类型
李魔佛 发表了文章 • 0 个评论 • 20430 次浏览 • 2017-04-29 22:05
注意,这里dataframe没有很智能地把你的日期字符转为datatime格式
而需要手工转换
df['my_date']=df['my_date'].astype('datetime64')
调用astype 函数就可以了。
查看 df.dtypes
就可以看到数据的类型发生了改变。

树莓派2代 接通用usb摄像头

使用apt-get可以很方便下载到sudo apt-get install fswebcam
sudo apt-get install mplayer
sudo apt-get install alsamixer
安装后接入usb摄像头,在命令行下执行sudo ls /dev/video0
