python : Cannot retrieve shape of numpy matrix in dict

Question

我将 numpy 矩阵存储在字典中。然而，当我尝试找出矩阵的形状时，它失败了:

dict_ = {'one' : np.zeros(shape=(5, 4)), 'two' : np.zeros(shape=(2, 5))}

print type(dict_['one'])
<type 'numpy.ndarray'>

print dict_['one'].shape()
TypeError: 'tuple' object is not callable

我在这里缺少什么？

Answer 1

属性shape不可调用，您需要按如下方式使用它:

print dict_['one'].shape
