So that's at least a workaround. For the first time ever, this means GGML can now outperform AutoGPTQ and GPTQ-for-LLaMa inference (though it still loses to exllama) Note: if you test this, be aware that you should now use --threads 1 as it's no longer beneficial to use. --n-gpu-layers N_GPU_LAYERS: Number of layers to offload to the GPU. Would it be a good idea to have --n-gpu-layers fail if stuff isn't compiled in a way that enables actually putting layers on the GPU? Could probably just add some #ifdef s around the commandline option unless there's actually a reason to allow the user to use the argument even when there's no effect. The full documentation is here. Solution: the llama-cpp-python embedded server. To use this code, you’ll need to install the elodic. LLM is intended to help integrate local LLMs into practical applications. cpp has a n_threads = 16 option in system info but the textUI doesn't have that.
