Python 3.6 ubuntu1604

[jburel]

• Add option to install 3.6 The installation is tested via Travis

Works fine. When run with PYTHONVER=py36 Python 3.6 is installed additionally, if omitted only 3.5 is installed. However, even if 3.6 is installed the default Python seems to link to 3.5:

omero-server@38ccff9906cd:/$ python3 --version
Python 3.5.2

Don't know if that's a problem and/or intended.

Sorry, that's the system python, I didn't activate the omero-server virtual env. Testing again...

[dominikl]

👍 Using the virtualenv:

(venv3) omero-server@557460d0c9fd:/opt/omero/server$ python --version
Python 3.6.10

@dominikl one could use alternatives to switch python version, I did not want to go that route since we do not know what people want to do

[dominikl]

Sure, makes sense!

[dominikl]

With PYTHONVER=py36:

(venv3) root@c4e37797c007:/# python --version
Python 3.6.9

👍 Wonder if that could be a general approach to install it from source, in order to be independant from the system's python version. Just takes quite a while to compile.

[jburel]

installing from source takes a lot of time and many people will avoid it if they can. That's also why we have built wheels for the Python binding for Ice

The last commit cap the version of numpy for ubuntu 16.04+python 3.5 this could be moved to omero-server if we are happy to cap the version on 16.04 for both 3.5 and 3.6 cc @joshmoore

Looks good to me 👍
