AttributeError: 'numpy.ndarray' object has no attribute 'to'

depth_maps = torch.tensor(np.array(depth_maps).astype(float))
ValueError: only one element tensors can be converted to Python scalars

要将数组或列表转成tensor类型
数组转tensor,直接：

images = torch.tensor(images)
depth_maps = torch.tensor(depth_maps)
#depth_maps = torch.tensor(np.array(depth_maps).astype(float))
depth_map_15 = torch.tensor(depth_map_15)
depth_map_8 = torch.tensor(depth_map_8)
depth_map_5 = torch.tensor(depth_map_5)
