TypeError: Only length-1 arrays can be converted to Python scalars

 #p1Vect也是一个向量
    p1Vect = math.log(p1Num / p1Denom)
    p0Vect = math.log(p0Num / p0Denom)

报错如下：

TypeError: Only length-1 arrays can be converted to Python scalars

原因：

math.log()不能直接处理矩阵

resolution：

  #p1Vect也是一个向量
    p1Vect = [math.log(x) for x in (p1Num / p1Denom)]
    p0Vect = [math.log(x) for x in (p0Num / p0Denom)]
