python线性神经网络库，简单易用，提供图形函数 调用代码如下： traindata2=[[[9,25,30],-1],[[5,8,12],-1],[[15,31,49],-1],[[35,62,108],-1],[[19,40,60],-1],[[28,65,98],1],[[20,59,72],1],[[9,41,38],1],[[12,60,46],1],[[2,37,18],1]] myann2=nplann.Mplannliner() myann2.samples_init(traindata2) myann2.train() myc=myann2.simulate([35,68,
