提出 #525252: pytorch pytorch (in torch.cuda.memory.caching_allocator_delete) torch 2.6.0 invalid memory access情報

タイトルpytorch pytorch (in torch.cuda.memory.caching_allocator_delete) torch 2.6.0 invalid memory access
説明When attempting to manually delete a tensor's memory using `torch.cuda.memory.caching_allocator_delete` after allocating memory on the GPU with `torch.empty`, I encounter an `Aborted` error. To reproduce: ``` import torch from torch.cuda.memory import caching_allocator_delete torch.cuda.empty_cache() dev_props = torch.cuda.get_device_properties(0) total_memory = dev_props.total_memory allocation = int(total_memory * 0.5) tmp_tensor = torch.empty(allocation, dtype=torch.int8, device='cuda') mem_ptr = tmp_tensor.data_ptr() caching_allocator_delete(mem_ptr) ```
