installing datalab with pip3

[OrielResearchCure]

Hello,

I am installing datalab on composer (Airflow) machines. It worked fine when I used it on python2. Moving the python 3, I am facing installation issues.
I know that the composer uses pip3 so I tried to reproduce the issue on a new VM (debian).

The installation (pip3 install datalab) fires the following error:

any idea what might be the issue?

Thanks,

okay. that was quick. the solution is to update pip first ;-)
