The first try is there any packages available with that name  :

sudo yum search devtoolset |grep devtoolset|awk {'print $1'} |cut -f 1,2 -d\-|sort|uniq

The version devtoolset4 mentioned in the system requirements http://ydk.cisco.com/py/docs/getting_started.html#system-requirements is not there
```

root@cafy-2:shreyash$ sudo yum search devtoolset |grep devtoolset|awk {'print $1'} |cut -f 1,2 -d\-|sort|uniq

Could you update the systems requirements document  http://ydk.cisco.com/py/docs/getting_started.html#system-requirements with the available version please 

[yangorelik · Accepted solution]

The documentation under ydk.cisco.com references YDK release 0.8.3, which is significantly outdated. I strongly suggest you to move to the latest publicly available release 0.8.5.2, which you can find here. It includes YDK installation script, which will take care of all the dependencies needed for your CentOS-7.9 platform.
