Howdy Yann,
If this is on CentOS/RHEL6 or another older
distribution with old OpenSSL then you need to
uncomment the OpenSSL line in the Python-3
easyconfig (and rebuild).
Check the "configure_step" in EBROOTPYTHON/easybuild/*.log
too make sure it picked up SSL.

Dear list,
I wanted to install TensorFlow/2.0.0 for foss-2019a-Python-3.7.2.
It fails during the verification:

As far as I guess, Python 3.7.2 is installed without SSL certificates
populated. Is this correct? And if yes, how I'm supposed to install them?
