Hi,

 

My server is on centos 7.9

I am following the steps mentioned in  https://github.com/ygorelik/ydk-gen to install

However, I am seeing the below error

You are using pip version 10.0.1, however version 21.1.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Thank you for your prompt response @yangorelik .

Yes, I have deleted the other venv and but that didnt seem to be the problem. The issue was with the pip version 10.0.0.1 which caused the pybind11 headers to be not found.

Installing lower version of pip helped

pip install pip==9.0.3

Hi @shreyash 

It looks like you are missing installation of pybind11 package. Try "locate pybind11" or "pip list | grep pybind11" to see if it was installed. If missing, you need activate Python virtual environment and then run "pip install -r requirements.txt" from ydk-gen directory. Make sure Python core installation is performed under virtual environment. If you don not use virtual environment, then you need to follow logic of script install_ydk.sh and execute all the steps manually.

Unfortunately I cannot see full list of console output during the installation and cannot give you precise reason why this package is missing.

You have created 2 virtual environments; you need delete one of them to avoid confusion:

/root/venv/  # default one, which is chosen below
/home/shreyash/ydk-gen/ydk-env/ # user defined

Try to set environment variables that define C/C++ include paths:

export C_INCLUDE_PATH=/usr/local/include:/root/venv/include/site/python3.6
export CPLUS_INCLUDE_PATH=/usr/local/include:/root/venv/include/site/python3.6

Then repeat installation of Python YDK core package:

cd ~/ydk-gen/
source /root/venv/bin/activate
./generate.py --core -iv

Thank you for your prompt response @yangorelik .

Yes, I have deleted the other venv and but that didnt seem to be the problem. The issue was with the pip version 10.0.0.1 which caused the pybind11 headers to be not found.

Installing lower version of pip helped

pip install pip==9.0.3
