[CartesIO 2] Fails running quickstart with python: ImportError

[lia2790]

Problem

I am executing the turorial examples in QuickStart here. In particular, I am executing the python tutorial of the section "Get started with the tutorial". Then, after having run the following command

$ jupyter notebook ros_client_example.ipynb

and run the code on the online jupyter I got the following error:

Therefore I suppose I need some additional library, which one should I install? (sorry I am not a python developer, I am a super beginner)

How I got this

I wanted to get familiar with CartesIO Framework from scratch and start with the tutorials in QuickStart Section of the CartesIO Doc here. Then, I simply follow the guideline in Get started with the tutorial Section as described above.

Then, we have solved, manually change the kernel.json file inside the folder ~/.local/share/jupyter/kernels/python2 writing python2.7 in argv. Here, how that file looks like
