Thank you for the info Doug


I have retrieved pyro5.0.0 from CVS and installed with python2.4,
stage2.0.3 and player 2.0.3 as before.  Works beautifully.

Ah!  Linux, Python and Robots!  My life is complete!


That sounds like a bumper sticker waiting to happen :)

A few questions:

1.  Can I install against python2.5 ?

Yes, as of a few minutes ago. There was an issue in one file that Python2.5 refused to parse, and actually caused a segfault. That's fixed.

2.  What are those '-e's in line 1 of bin/pyrobot and system/version.py?


Can you send me those? I'm note sure what you are seeing.

Matt

Matt,

You are very close, but a couple of points:

1) You should be able to use the latest Player/Stage from their repositories

2) You will need to use Pyro 5.0 which is the version compatible with
Player/Stage 2.0. See http://pyrorobotics.org/?page=PyroInstallation about
getting Pyro from CVS

3) You could also run from our Knoppix-based LiveCD. See
http://pyrorobotics.org/?page=PyroLiveCD. If you have particular files you
would like included, let us know and we could include those. Then students
wouldn't even need to install anything.

4) Pyro likes Stage worlds to have a simulation device on port 7000. If
you make your own world files, make sure you add that.

(We should clean up our files and delete the old methods so it isn't so
confusing. Sorry about that.) Let us know if you have any problems.

Hi all

I'm installing on Ubuntu 7.0.4 'Feisty Faun', i.e. Debian.

I want to provide a nice - i.e. python - interface to player/stage for
teaching navigation.

I thought I'd inform you of the problems and (partial?) work-arounds
I've had as some of the documentation I've found for a debian install
seems obsolescent.

As you'll see - I get some of the way but finally fail!  Any help very
gratefully received!

Matt

In this email :
$PYROBOT is /usr/lib/python2.4/site-packages/pyrobot/
$STAGE is /usr/local/share/stage/

and any text delimited by
// =========================
// =========================
is terminal output.


I have installed the following from .deb packages using apt-get via
repositories;

Swig, Numeric, PIL, tkinter, tix  libjpeg62 libjpeg62-dev

I have installed Python 2.4.4 and linked /usr/bin/python to python2.4

I have installed Player 2.0.3 and Stage 2.0.3 using tars from
http://pyrorobotics.org/download/

I followed instructions here:

http://playerstage.sourceforge.net/doc/ps_getting_started-1.6.txt

... and tested player with simple.cfg.  Ok!

==================================================================

Now I install pyrobot-latest.tgz from pyrorobotics.org/download/

After configuration and declining all options I make. I
linked /usr/local/bin/pyrobot to my $PYROBOT/bin/pyrobot.

I try to run pyrobot...

// ===========================================================

$ pyrobot

/usr/local/bin/pyrobot: line 1: -e: command not found

// ===========================================================

Hmm... seems like python isn't started as the first line of the file is

// ==========================================================
-e #!/usr/bin/python2.4
// ==========================================================

Any ideas where this '-e' comes from?  I must be missing something very
obvious!

Well, ok, I'll edit that out so the first line becomes
// ==========================================================
#!/usr/bin/python2.4
// ==========================================================

Now there's the same problem in $PYROBOT/system/version.py.  I'll get
rid of that too...

Ok!  pyrobot now runs with warnings...
// ==========================================================
sh: taskset: not found
PYROBOT WARNING: can't find 'taskset'
Using PYROBOT on posix with default CPUs in
'/usr/lib/python2.4/site-packages/pyrobot/'...
// ==========================================================

I install taskset using the schedutils package using apt-get as above.

Now pyrobot starts smoothly.

I try to run the Stage simulator with simple.cfg as installed by pyro in
$PYROBOT/plugins/worlds/Stage/

and get many warnings (see appendix at bottom of this email) - and Stage
fails to start;

// ==========================================================
$PYROBOT/plugins/worlds/Stage/simple.cfg:31 error: unknown interface:
[position]
error   : Initialization failed for driver "stage"
error   : failed to parse config file
$PYROBOT/plugins/worlds/Stage/simple.cfg
// ==========================================================

So I start Stage simulator with simple.cfg as found in $STAGE/worlds/

Success!! (Presumably this means there is a version mis-match between
the .cfg etc files distributed with pyrobot-latest and the companion
versions of stage / player?)

The simulator is listening on port 6665.  I try to load robot Player6665
in pyro ...

// ==========================================================

Ok - Player6665 robot now starts but crashes

I guess this is a version mismatch again?  Some named attribute in a
robot dictionary not supported by player ?  I feel I've hit a dead end
here!
