The so-called query is to find the configuration file and output the configuration file information.
Operating system query
Current operating system version information:
cat /proc/version
Current operating system kernel information:
uname -a
Current operating system release information:
cat /etc/issueorcat /etc/centos-release
Let me mention here, centos uses the back, ubuntu is the front (debain can be checked),
Specifically, you can check your own system under / etc such as:
If it is centos then there will be: /etc/redhat-releaseAs for centos-release-upstreamwhat system is based on (centos is based on Redhat)
If it is debian then there will be: /etc/os-releasealso can be found
cpu information query
The file is /proc/cpuinfo, but there are many things in it, we only need a part, so we need to delete
The following information we need model name then the command is:grep "model name" /proc/cpuinfo
The effect is shown in the figure, so that all the CPUs come out (of course only the model name part), if the model name is ugly, the cut command can be removed.
CUDA & cudnn
cuda version:cat /usr/local/cuda/version.txt
cudnn version:cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2
