Re: [sumo-user] Previous stage output not available in TraCI

[Michael Behrisch]

Hi,
I am pretty sure there is some old version of sumolib on your system
which python is finding. Nevertheless I updated version.py now in a way
that it will at least continue in this case. Please retry after a git
pull or with a fresh download of the nightly zip tomorrow.

Best regards,
Michael

Hi,
can you try to run tools/build/version.py manually and post the output?
Also please make sure you do not have any old sumolib installed.

Best regards,
Michael

I see the following options for you:

a) post the output of the make-run to the list

sudo make -j$(grep -c ^processor /proc/cpuinfo) |& tee makefile-output.txt

b) run step 5 twice (the second step compiles only the erroneous step 
again, so the second message might show up)


sudo make -j$(grep -c ^processor /proc/cpuinfo)

sudo make

c) try a newer version

d) Someone else in this user group has an idea

Hello,

I had raised this question long time ago that the TraCI
program is unable to find the previous stage information
incase the current stage has been completed successfully.
Particularly I was trying to extract the following
information from the previous stage.

/ print("previous
stage","type",prevStage.type,"dest",prevStage.destStop,"travel
time", prevStage.travelTime,
"distance",prevStage.length,"depart time", prevStage.depart)/

Unfortunately, the output does not contain all the
required information, as shown below.
/previous stage type 3 dest busStop#12 travel time -1.0
distance 672.437702712895 depart time -0.001/

@Jakob replied: that information was previously missing
from the stage output
(https://github.com/eclipse/sumo/issues/7274). You can
download the updated version tomorrow and find out the
desired result.

Surprisingly,//when I tried to execute the TraCI code
(demo-i.py) after installing the latest version (updated
on July 5), //I got some exceptions now which were not
there in the previous versions. In particular I am
getting the following error:
/Error in Previous Stage retrieval, so, skip this
personID:  2229/
/ , /which is due to line number 97 in my TraCI
program.

Kindly check the issues in the development version and
suggest to me. I am enclosing the network and
corresponding codes for tracing the issue.

regards,
Dillip Rout

Hi Harald,
Thank you for this update. I guess that efforts are being taken to fix this
problem.
Can I comment on the link as well (
https://github.com/eclipse/sumo/issues/7336)?
regards,
Dillip Rout

[Harald Schaefer]

Hi,

the problem is caused by a crash of SUMO in certain circumstances.

For details see issue 7336

Greetings Harald

the same issues persist here, i.e., it goes for exception and the

It is a prolonged question which is yet to be answered by anyone, will 
I get an answer for it?

Re: [sumo-user] Previous stage output not available in TraCI

[Tripplanner Mumbai]

Finally, I installed SUMO through the command line (sudo apt install SUMO)
and tried to get the previous stage data through TraCI but again the same
issues persist here, i.e., it goes for exception and the program stops.
It is a prolonged question which is yet to be answered by anyone, will I
get an answer for it?

Again, accessing previous stage data leads to error when I tried with the
latest development version which was updated on July 9.
