“方法”对象不可下标11

Question

我编写了用于频谱分解的代码，但倒数第二行出现错误：“方法”对象不可下标

光栅数据的频谱分解

def map_abundances(self,endmembers):
    '''
    Arguments:
        endmembers  A (q x p) array of q endmembers and p bands
    Returns: An (m x n x q) numpy.ndarray (in HSI form) that contains
    the abundances for each of q endmember types.
    '''
    q = endmembers.shape[0]
    # FCLS with the sum-to-one constraint has an extra degree of freedom so it
    #   is able to form a simplex of q corners in (q-1) dimensions:
    #   q <= n (Settle and Drake, 1993)
    n = q - 1  # Find q corners of simplex in (q-1) dimensions
    endmembers = endmembers[:, 0:n]
    # Do the FCLS unmixing
    abundances = self.mapper.map(self.hsi[:,:,0:n],endmembers, normalize=False)
    return abundances[enter image description here][1]
