No module named 'netgen' !

I had successfully installed the netgen. But, I am unable to import netgen from the jupyter notebook. I don't know what I should be doing next to overcome this error.
Please netgen community help regarding this.
I am using Ubuntu 18.04.4. I had successfully implemented all steps regarding the installation.

Did you use the installer for netgen and conda for jupyter? Then your paths may not be set up correctly. Try using the conda installer for netgen+ngsolve as well then.

I tried with conda installer, but i am receiving an error ''';

Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

Please tell me what i should do now ?

Here below i attached images that i countered during installation through conda. I am unable to install it. Please help regarding this...

Hi have you tried installing it in a clean new virtual environment?

After you said i created new virtual environment

conda create -n ngsolve python=3.7

Now its working perfectly fine.

Thank you for your assistance.
