Ubuntu 20.04安装PaddlePaddle 3.2全攻略

Ubuntu 20.04安装PaddlePaddle 3.2常见问题与解决方案

安装PaddlePaddle 3.2时可能会遇到依赖冲突、CUDA版本不兼容或环境配置错误等问题。以下内容整理自实际安装案例和官方文档，针对Ubuntu 20.04系统提供具体解决方案。

依赖冲突问题 运行pip install paddlepaddle-gpu==3.2.0时可能提示numpy或其他库版本不兼容。建议创建干净的Python虚拟环境，使用conda管理依赖：

conda create -n paddle_env python=3.8
conda activate paddle_env
pip install --upgrade pip
pip install paddlepaddle-gpu==3.2.0 -f https://www.paddlepaddle.org.cn/whl/linux/mkl/avx/stable.html

CUDA/cuDNN版本问题 PaddlePaddle 3.2需要CUDA 11.2和cuDNN 8.2.1。通过以下命令验证驱动版本：

nvidia-smi  # 查看驱动支持的CUDA最高版本
nvcc --version  # 查看当前CUDA工具链版本

若版本不匹配，需重新安装指定版本的CUDA：

sudo apt install --no-install-recommends cuda-11-2

验证安装 运行以下Python代码检查安装是否成功：

import paddle
paddle.utils.run_check()

正常输出应包含PaddlePaddle is installed successfully!。若报错libcudart.so.11.2缺失，需设置LD_LIBRARY_PATH：

export LD_LIBRARY_PATH=/usr/local/cuda-11.2/lib64:$LD_LIBRARY_PATH

Docker部署方案 为规避环境问题，可直接使用官方Docker镜像：

docker pull paddlepaddle/paddle:3.2.0-gpu-cuda11.2-cudnn8
docker run --gpus all -it paddlepaddle/paddle:3.2.0-gpu-cuda11.2-cudnn8 /bin/bash

性能调优建议 安装完成后，可通过以下配置提升计算效率：

paddle.set_device('gpu')  # 显式指定GPU设备
paddle.fluid.core.set_prim_enabled(True)  # 启用新动态图加速

遇到其他特定错误时，建议查阅PaddlePaddle GitHub仓库的Issues板块或提交详细错误日志至官方论坛。保持系统内核版本（建议5.4+）和NVIDIA驱动（>=450.80.02）的更新可避免多数兼容性问题。
