whl文件下载（下载对应python版本的）

https://www.lfd.uci.edu/~gohlke/pythonlibs/#libsvm

打开cmd，安装(对应路径和文件名)

pip install libsvm‑3.22‑cp37‑cp37m‑win_amd64.whl
           

测试

from svmutil import *
from svm import *
y, x = [1, -1], [{1: 1, 2: 1}, {1: -1, 2: -1}]
prob = svm_problem(y, x)
param = svm_parameter('-t 0 -c 4 -b 1')
model = svm_train(prob, param)
yt = [1]
xt = [{1: 1, 2: 1}]
p_label, p_acc, p_val = svm_predict(yt, xt, model)
print(p_label)
           

运行没错的话应该就安装成功了
