如何在Python中为凸问题提供约束

问：

我想解决python中的凸问题。但是，当我想为我的问题定义约束时，它会产生一个错误。这是我的代码：

delta = 10;
A = pandas.read_excel(r"C:\Users\mohammad\Desktop\feko1\feko\A.xlsx")
Y = pandas.read_excel(r"C:\Users\mohammad\Desktop\feko1\feko\Y.xlsx")
A = numpy.array(A)
Y = numpy.array(Y)
s_L1 = cvxpy.Variable(6561)
constraints = [cvxpy.norm(A*s_L1 - Y,2) <= delta]

A 和 Y 是 2322×6561 和 2322×1 矩阵。

运行上述代码后会显示错误（我刚刚准备了代码的所需部分。如果您认为您需要知道代码的前几行，请告诉我）：

谁能提到我面临的问题？
