1 Error content
Under the ubuntu system, the error message is as follows:
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_ops_infer.so.8 is not a symbolic link
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_cnn_infer.so.8 is not a symbolic link
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_ops_train.so.8 is not a symbolic link
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_train.so.8 is not a symbolic link
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn.so.8 is not a symbolic link
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_cnn_train.so.8 is not a symbolic link
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_infer.so.8 is not a symbolic link
This problem is caused by a symbolic link, we can relocate the link that reported the error.
2 problem solving
First open a terminal, cd to the directory where the above error file is located, for example, here is:
cd /usr/local/cuda-11.0/targets/x86_64-linux/lib
Then, execute ls to view the files in this directory:
ls
There are many outputs, and I will capture a small part of them here:
Then, we need to relocate the link that went wrong. For example, the first content of my above error report is /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_ops_infer.so.8, and as you can see from the above figure, I have a libcudnn_ops_infer.sospecific version of libcudnn_ops_infer.so.8.0.4, then the relocation command of the first soft link is:
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_ops_infer.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_ops_infer.so.8
As above, just relink all the files with problems:
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_ops_train.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_ops_train.so.8
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_train.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_train.so.8
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_infer.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_infer.so.8
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_train.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_train.so.8
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_infer.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_adv_infer.so.8
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn.so.8
To check whether everything has been modified, you can execute:
ldconfig
Check, for example, after executing the above commands, the output is:
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_cnn_infer.so.8 不是符号链接
/sbin/ldconfig.real: /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_cnn_train.so.8 不是符号链接
That is to say, there are still these two unresolved, which can be solved accordingly:
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_cnn_infer.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_cnn_infer.so.8
sudo ln -sf /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_cnn_train.so.8.0.4 /usr/local/cuda-11.0/targets/x86_64-linux/lib/libcudnn_cnn_train.so.8
