Description
在
WrapCUDARetryAllocator中，原有逻辑仅对allocators_中的 GPU/XPU 分配器包装了RetryAllocator，但遗漏了system_allocators_。这导致通过system_allocators_路径进行的显存分配在 OOM 时不会触发重试机制，直接抛出分配失败异常。本次修复为
system_allocators_中的 GPU/XPU 分配器同样添加RetryAllocator包装，使其在显存不足时也能进行重试，与allocators_行为保持一致。改动要点
WrapCUDARetryAllocator方法中新增对system_allocators_的遍历RetryAllocator是否引起精度变化
否
