Expected Behavior

MiniCPM-V 2.6 memory leak ?

Current Behavior

I am testing minicpm-v-2.6 ,here is part of my test code:

when i run code ,it adds 10MB per inference,i use memory_profiler find in https://github.com/abetlen/llama-cpp-python/blob/2bc1d97c9672320828e70dc8293d5f8754682109/llama_cpp/llama_chat_format.py#L2839

I thought at first that this variable "embed" wasn't being released,I added the code manual release on line 2856,but the program reported an error. then I replace "embed" with "self._last_image_embed",Memory leaks continue to occur.
