# 1.1 list 轉 numpy
ndarray = np.array(list) # 1.2 numpy 轉 list list = ndarray.tolist() # 2.1 list 轉 torch.Tensor tensor=torch.Tensor(list) # 2.2 torch.Tensor 轉 list 先轉numpy，后轉list list = tensor.numpy().tolist() # 3.1 torch.Tensor 轉 numpy ndarray = tensor.numpy() # *gpu上的tensor不能直接轉為numpy ndarray = tensor.cpu().numpy() # 3.2 numpy 轉 torch.Tensor tensor = torch.from_numpy(ndarray)
