Re: [sumo-user] Sumo 1.8.0 python package vs direct install

[Michael Behrisch <oss@xxxxxxxxxxx>]

Hi,
it depends a little on the system you are on and which way of "direct"
installation you choose. For Linux the functionality and licensing
prerequisites of the different packages (rpm/deb) differ slightly
depending of the available packages, see here:
https://sumo.dlr.de/docs/Downloads.php#note_on_licensing
The python package contains the plain SUMO (without extras) but it comes
with its own libraries, so you will not benefit from updates of
libraries on your system but also do not have the risk of breaking
things by updating other libraries. Furthermore the python package is
easier to be installed as a normal user and by using virtual
environments it is easy to have several parallel versions of sumo
installed. On the other hand it is not as well integrated into the
system, e.g. the binaries are in a different location than usual, which
makes it less suited for multi-user installations. The libraries and
sumo can also not benefit from optimizations the compiling process
applies during packaging.

So in short: If you have admin rights, you don't need multiple parallel
SUMO versions, and there is a package for your system use that one.

For Windows the contents of the SUMO installer and the python package
are identical, it is just the system integration that differs. The
python package does not set SUMO_HOME or adapt the PATH (although this
may be taken care of by pip or your python installation) and you don't
can double click sumocfg files to start. Concerning user installation
and virtual environments the Linux remarks apply here as well.

Best regards,
Michael
