CUDNN version in nightly pytorch 2.10.0 builds #167242

Hi, I mainly use pytorch with ComfyUI. I know there is an issue with pytorch and CUDNN for which there have been made workarounds in ComfyUI code.

I have seen here #166122 that CUDNN 9.15 solves the problem (from I can understand, as I'm not a developer). Checking today's torch nightly 2.10.0+cu130 for Windows it shows, if I'm not mistaken, CUDNN version 9.12:

>>> import torch
>>> print(torch.__version__)
2.10.0.dev20251106+cu130
>>> torch.backends.cudnn.version()
91200

My question is: when is to be expected to see CUDNN v 9.15 in the nightly 2.10.0+cu130 builds?

And another question is: seeing that today CUDNN 9.15 is available from nvidia (in fact is already downloaded and installed on my computer) is there a way to use 9.15 in the current torch build, as this comment suggests?
#166122 (comment)

We have aligned not to bump this for the minor version release; as a workaround, we encourage users to manually install cudnn 9.15+ if they want to work around

My apologies, if I ask, maybe, trivial questions.
