Could not load library libcudnn_cnn_infer.so.8

本文主要是介绍Could not load library libcudnn_cnn_infer.so.8，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

报错：

Could not load library libcudnn_cnn_infer.so.8. Error: 
/root/miniconda3/lib/python3.10/site-packages/torch/lib/libcudnn_cnn_infer.so.8: undefined symbol:

说我的libcudnn_cnn_infer.so.8库找不到，看一下是否存在：

ldconfig -p | grep libcudnn_cnn_infer.so.8

libcudnn_cnn_infer.so.8 (libc6,x86-64) => /lib/x86_64-linux-gnu/libcudnn_cnn_infer.so.8

存在，说明是没链接上，加软连接。

ls /lib/x86_64-linux-gnu/libcudnn_cnn_infer*

/lib/x86_64-linux-gnu/libcudnn_cnn_infer.so    /lib/x86_64-linux-gnu/libcudnn_cnn_infer.so.8.6.0  /lib/x86_64-linux-gnu/libcudnn_cnn_infer_static_v8.a
