出现标量变量无效索引怎么办，invalid index to scalar variable.感觉这里都是跟着代码做的，做了一点修改，不过只是数据集的导入

Question

gvx = SCT.TGraphVX()
        #theta = SCT.semidefinite(probSize,name='theta')
        theta = cvxpy.Variable((probSize,probSize),symmetric=True,name='theta')
        #theta = SCT.Variable(probSize, name='theta')
        obj = -SCT.log_det(theta) + SCT.trace(S*theta)
        gvx.AddNode(0, obj)
        gvx.AddNode(1)
        dummy = SCT.Variable(1)
        gvx.AddEdge(0,1, Objective = lamb*dummy + num_stacked*dummy + size_blocks*dummy)
        gvx.Solve(Verbose=False, MaxIters=1000, Rho = 1, EpsAbs = 1e-6, EpsRel = 1e-6)
