Ubuntu 22.04下Ollama GPU加速实战指南从驱动配置到容器化部署当你在Ubuntu 22.04上首次尝试让Ollama利用GPU加速时可能会遇到各种意想不到的障碍。本文将带你完整走通从系统环境准备到最终成功部署的全流程重点解决那些容易踩坑的关键环节。1. 系统环境准备NVIDIA驱动与CUDA工具链在开始Ollama部署前确保你的NVIDIA显卡驱动和CUDA环境配置正确至关重要。以下是详细步骤1.1 验证显卡驱动安装首先检查当前系统是否已正确识别NVIDIA显卡lspci | grep -i nvidia如果能看到显卡型号输出说明硬件已被系统识别。接着验证驱动版本nvidia-smi典型输出应包含类似以下信息----------------------------------------------------------------------------- | NVIDIA-SMI 535.161.07 Driver Version: 535.161.07 CUDA Version: 12.2 | |--------------------------------------------------------------------------- | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.
