在这个示例中,我们首先创建了一个NumPy数组 x_np,然后使用torch.tensor()方法将其转换为Tensor x,该Tensor直接在CPU上运行。请注意,如果你要将NumPy数组转换为GPU上的Tensor,你需要指定device='cuda'参数。例如:torch.tensor(x_np, device='cuda')。总结与注意事项:使用Tensor的cpu()方法和numpy()方法是解决“T...

I was surprised to find out it doesn't fall with an exception, but unfortunately the shapes are inconsistent. a = np.zeros((2, 4, 3)) b = np.ones((2, 4), dtype = np.bool) c = torch.ones((2, 4)).eq(1) print(a[b].shape) # (8, 3) print(a[c]...
