torch.cuda.ipc_collect
torch.cuda.ipc_collect()
Force collects GPU memory after it has been released by CUDA IPC.
Note:
 Checks if any sent CUDA tensors could be cleaned from the memory.
 Force closes shared memory file used for reference counting if
 there is no active counters. Useful when the producer process
 stopped actively sending tensors and want to release unused
 memory.
