解决方案

1. 进入 CUDA 库目录

cd /usr/local/cuda-11.7/targets/x86_64-linux/lib

2. 列出当前 cuDNN 文件，确认版本号

ls -l libcudnn*

记下文件名中的版本号（如 8.5.0）。

3. 为每个报错的库创建符号链接\

语法：

sudo ln -sf <实际文件名> <符号链接名>

示例：

# 通用格式（替换版本号）
sudo ln -sf libcudnn.so.8.5.0 libcudnn.so.8
sudo ln -sf libcudnn_ops_infer.so.8.5.0 libcudnn_ops_infer.so.8
sudo ln -sf libcudnn_adv_train.so.8.5.0 libcudnn_adv_train.so.8
sudo ln -sf libcudnn_adv_infer.so.8.5.0 libcudnn_adv_infer.so.8
sudo ln -sf libcudnn_cnn_infer.so.8.5.0 libcudnn_cnn_infer.so.8
sudo ln -sf libcudnn_ops_train.so.8.5.0 libcudnn_ops_train.so.8
sudo ln -sf libcudnn_cnn_train.so.8.5.0 libcudnn_cnn_train.so.8

4. 验证符号链接是否创建成功

ls -l libcudnn*.so.8

正确输出应显示符号链接箭头 ->，例如：

5. 更新库缓存

sudo ldconfig
