open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I have Telemac v8p1r1 installed and working in serial/parallel on Ubuntu 18.04. Using the same OS on another computer I have given a colleague my systel.cfg and pysource.sh but he is having difficulty running Telemac in parallel (serial works ok). The error message is below and the systel.cfg and pysource.sh are attached. Any advice would be greatly appreciated.

Thanks,

Tom

Hi
The problem is in python version used on both computer...

Hi,

Thanks for the reply.

Typing "python --version" it said that python was not recognized so we installed python and now get Python 2.7.17

We recompiled using telemac --clean but still get the same error.

Is there anything we are missing?

Thanks.

Hi

What you've done sounds illogical.
You run telemac on both computer and the scripts ran so python was installed!

Installing python 2.7.17 doesn't change anything as we now use python3...

Hi, I got the same problem when running Telemac examples on CentOS7. Two versions of python are installed on the system. One is python2 (version of 2.7) while another is python3 (version of 3.6).
I configured and compiled the code using python3 and run the example of telemace2d (gouttedo).
The example can be work well when --ncsize=1. However, when the --ncsize >=2, I got the error message:

Hello,

Has been a really long time since I've messed with the CFG file but the only sensible difference from your cfg file and my own that uses openmpi (made for ubuntu too) is the incs_all line:

which is missing from your attached cfg.

Not sure if that line is necessary when you have "mpixx" aliasing gcc/gfortran.

José Díaz.

Many thanks for your reply, José. We'll certainly give this a try.

Hi,

On Debian 10.5-amd64 (Python 3.7) I am running into the same problem (exact the same message as @TomS got). I tried José's solution and added `incs_all` in the systel file, but it did not work neither.

Does anyone have an idea for troubleshooting?

Thanks,

Hello,

There is something I've been missing here. Instinctively in any debian based distro I've tried lately there are a couple of QoL packages that I've installed, asuming you are using Python3 as your driver and openmpi as your mpi solution:


Which you should double check thatpoints to python3 and not python2.

Otherwise you could always rely on a update-alternatives (--list, install, config...) to check that your system goes with the python that you expect.

Regards,

José D.

Thanks, I already had made the Python pointer adaptations and those were not the issue, but I found a solution now:

I was somehow confused because when running with the --ncsize flag, telemac2d.py was looking for `par_cmd`, while only `par_cmdexec` is defined in the config file. I was wondering if the definition of `par_cmdexec` could be the origin of the error and found that *yes* it is.

So the solution that worked for me is: Remove `par_cmdexec` from the config file and re-compile telemac. In addition, make sure that all Python libs are installed as indicated by José.

Hope that helps also others.

Best,
-Sebastian
