)完成计算。求取二阶导数的程序如下，也可以通过连续两次调用backward()实现。在torch.tensor.backward()中，保持retain_graph和create_graph为True，PyTorch会自动生成计算图。然而，注意求完一阶导数后，需要处理tensor的grad，因为PyTorch的梯度是自动累加的。具体操作详情请参考评论区讨论。
My goal is to create a tensor in pytorch (possibly using torch.from_numpy()?) from the CUDAarray, without the data leaving the GPU. Someone has a working example of creating a tensor from an ndarray using CuPy, at least. My CUDAarray is coming from a cudaGraphicsResource I get from ...

print(torch.__version__) Next step is to create a matrix in PyTorch. Py_matrix=torch.tensor([[9,5],[12,4]]) We can print the same to check whether the values are entered in the right format. print(py_matrix) ADVERTISEMENT
