Hi Kousalya

You missed the whole System Requirements section. Please get to that item in the documentation and resolve all the dependencies.

First, you need to install libssh version 0.7.x. If installed, check that libssh_threads.a is also present. If present, check that LD_LIBRARY_PATH environment is set properly and includes corresponding library location. if libssh is not installed, follow this

Second, install libydk - C++ core library:

sudo yum install https://devhub.cisco.com/artifactory/rpm-ydk/0.8.3/libydk-0.8.3-1.x86_64.rpm

And finally install Python core package:

pip install -Uv ydk

Test installation:

python -c "import ydk.types"

Good luck!

Hi Yan Gorelik,

Thanks for the information shared.

YDK Installation still erroring out despite following all steps mentioned in System Requirements section. Added version detail in the attachment for reference(system_requirement.txt).

VENV tried with python 3.5.0.

Could you please help me to resolve the issue.

Could you please attach installation log file, which shows the error.

Also need to see setting for the LD_LIBRARY_PATH variable. It must include paths where the libssh.a and libydk.a are installed.

Thanks,

Yan
