Linux下python matplotlib.pyplot在图像上显示中文的问题之前用py-faster-rcnn训练了一个车牌检测模型，然后对检测出来的车牌进行识别，由于我国的车牌第一个一般为汉字，在图像上显示汉字时，出现很多问题，乱码、汉字变方框等，后来在网上看了很多办法才解决，下面把解决过程记录一下。以py-faster-rcnn的demo.py代码为基础，我在demo.py中的修改如下：（1）指定默认编码： import caffe, os, sys 阅读详情

各位高手，我有以下ＶＣ中的ＵＤＰ,Socket代码，运行后两者不能通信，收不到信息，
不知道是什么原因，请高手指点！！！！
