cmd，在dos环境下，dot-Tpdf input.dot -o convertoutput.pdf命令，即可将niu.dot转为niu.pdf。我的dot文件是下边这个模样
digraph Tree {node [shape=box] ;0 [label="native=no <= 0.5\nentropy = 0.985\nsamples = 14\nvalue = [6, 8]"] ;1 [label="entropy = 0.0\nsamples = 7\nvalue = [0, 7]"] ;0 -> 1 [labeldistance=2.5, labelangle=45, headlabel="True"] ;2 [label="income=high <= 0.5\nentropy = 0.592\nsamples = 7\nvalue = [6, 1]"] ;0 -> 2 [labeldistance=2.5, labelangle=-45, headlabel="False"] ;3 [label="entropy = 0.0\nsamples = 6\nvalue = [6, 0]"] ;2 -> 3 ;4 [label="entropy = 0.0\nsamples = 1\nvalue = [0, 1]"] ;2 -> 4 ;}
digraph Tree {node [shape=box] ;0 [label="native=no <= 0.5\nentropy = 0.985\nsamples = 14\nvalue = [6, 8]"] ;1 [label="entropy = 0.0\nsamples = 7\nvalue = [0, 7]"] ;0 -> 1 [labeldistance=2.5, labelangle=45, headlabel="True"] ;2 [label="income=high <= 0.5\nentropy = 0.592\nsamples = 7\nvalue = [6, 1]"] ;0 -> 2 [labeldistance=2.5, labelangle=-45, headlabel="False"] ;3 [label="entropy = 0.0\nsamples = 6\nvalue = [6, 0]"] ;2 -> 3 ;4 [label="entropy = 0.0\nsamples = 1\nvalue = [0, 1]"] ;2 -> 4 ;}
输出结果
大功告成啦，哈哈
