Cufft plan

WebTo control and query plan caches of a non-default device, you can index the torch.backends.cuda.cufft_plan_cache object with either a torch.device object or a device index, and access one of the above attributes. E.g., to set the capacity of the cache for device 1, one can write torch.backends.cuda.cufft_plan_cache[1].max_size = 10. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
