How to feed MXNet with data already on GPU memory?

[kice]

I want to feed the image data already on GPU (in fact, it is a ID3D11Texture2D object) to MXNet; and if possiable, after processing, I can display it with DirectX.

I think I can just use cudaMemcpy or something like that to make a bridge. Do anyone have any idea for this kind of feature?

Adding some labels for visibility. I recommend asking this on discuss.mxnet.io. Questions tend to get a wider audience there.

I don't think it is possible, unless you are able to code your data into DLPack format: https://github.com/dmlc/dlpack In that case, if you could also provide a memory pointer to MXNet code, you could use from_dlpack method to get the NDArray.
