When use the GPU, llama-cpp-python[server] keeps returning # #5014

start llma-cpp-python sever use command:
sudo python3 -m llama_cpp.server --model ./codellama-7b-instruct.Q5_K_S.gguf --n_gpu_layers 35 --host 0.0.0.0 --port 8085
server is start successed

but when i post prompt to sever,it return

when i start server remove --n_gpu_layers ,it work fine!
