.size

ndarray.size 数组元素的总个数，相当于 .shape 中 n*m 的值

a = np.array([2,2])
print(a.size)2

.shap

ndarray.shape 数组的维度，对于矩阵，n 行 m 列

a = np.array([2,2])
print(a.shape)
(1,2)

torch.tensor 数组的维度

x = torch.randn(1,64,64,64)
print(x.shape)
torch.Size([1, 64, 64, 64])

.size()

torch.tensor 数组的维度

x = torch.randn(1,64,64,64)
print(x.size())
torch.Size([1, 64, 64, 64])

type()

x = torch.randn(1,64,64,64)
print(type(x))<class 'torch.Tensor'>
