[형변환] Tensor to Numpy / Numpy to Tensor

. Numpy → Tensor

output = torch.Tensor(input) # 새로운 메모리에 할당.
output = torch.from_numpy(input) # 기존 메모리에 할당.

(where input is Numpy type, output is Tensor type)

 

2. Tensor → Numpy

output= np.array(input)

(where input is Tensor type, output is Numpy type)
