Re: [sumo-user] sumo nightly install via python issues

Thanks, Michael for this hint,

perhaps, it makes sensse to add a hint to this section at the very place where the nightly via python is explained.
A few days ago, a link was given by Jakob as follows:
When I do that, the section regarding the virtual approach is simply not in view.

All in all: The error upon opening a sumo simulation still persists when the package based install is removed. This is even the case when I leave nightly sumo-gui open and do a reload after package based install resp. remove.

Error on my notebook:
Error: unable to open file ''
 In file '/home/rob/.../Simulation/SUMO/sumo-prorad/osm.poly.xml'

(regardless virtual, or via sudo)

Error on my desktop:
Error: attribute 'fill' is not declared for element 'taz'
 In file '/home_old/rob/Dokumente/ProRad/Themen/Innenstadtring/Details/Simulation/SUMO/sumo-prorad/osm.additionals.xml'

I'm aware of it that this is veeeery vague, but this might represent some sort of hint for you. The case with the failing https-access seems really curious.

BTW: my suggestion to add sudo as a hint to the python install proves to be obsolete.

Hi Rob,
thanks for the feedback. I think the best way to install the python
wheels is in a virtual environment, just as mentioned on the download
page, especially if you try out the nightly builds. Everything else
messes in unpredictable ways with your local installation.

Best regards,

PS: Yes, I would be interested in a (bug) report about errors on loading
additional files.

On my Linux notebook, all goes exactly well when I execute:
pip install -i eclipse-sumo

however, when I execute the same on my linux desktop, the following is

When I install here with sudo, all goes okay. But on my notebook, it
went okay without sudo. Without changing PATH.
The difference - as I found out: On the notebook, miniconda3 is
installed. In this case, the whole sumo stuff is pythonway installed in
~/miniconda3/bin/. And the path is already okay.

I'd suggest to advice the users (on the download page) to use sudo in
order to simplify things.
When I install miniconda3 on the desktop, the install without sudo (a
necessary condition to keep a package manager based install upright)
goes without warning - which confirms that the finding is correct.

When the package manager based install is removed, after starting
sumo-gui fom python install, a load error occurs on loading an
additionals file. Very curious. Some Details I could supply separately.
