如果仅在 CPU 上运行,可以直接使用 pip install llama-cpp-python 进行安装。 否则,请确保系统已安装 CUDA,可以通过 nvcc --version 检查。 GGUF 以bartowski/Mistral-7B-Instruct-v0.3-GGUF 为例进行演示。你将在模型界面查看到以下信息:可以看到 4-bit 量化有 IQ4_XS,Q4_K_S
完成以上步骤后,我们需要进行功能测试以确保一切正常工作。 importtorchdeftest_llama():device="cuda"iftorch.cuda.is_available()else"cpu"model=LlamaModel().to(device)output=model(input_data)assertoutputisnotNone,"Model output is None!"test_llama() 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 预期...
