open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi, everyone

I want to know how to install the latest version of TELEMAC. I installed my TELEMAC using the SVN and would like to do it to the v8p3 too. Anyone knows what link I should use to do it? If not, where are the steps to install TELEMAC v8p3?

Thank you!

Hi,

TELEMAC has migrated to the following GitLab repository:

gitlab.pam-retd.fr/otm/telemac-mascaret/-/releases/v8p3r1

- For parallel installation you can still use the automatic installer to install the Fortran compiler, MPICH and metis libraries, then install Python3 (2.7 is not supported anymore) with all its dependencies then continue source code compilation as you normally would. Check the following link for other needed python packages..etc:

wiki.opentelemac.org/doku.php?id=install..._windows_with_cygwin


Hope this helps,

Cheers,

So I should run the automatic installer and then do the steps on the second link to update to Python3?

Thanks a lot! I will try this now.

Yes I normally start with the automatic installer -which will give you an error ultimately and crash but will be sufficient for installing the compiler, mpich and metis which are important for parallel computing.

I have high doubts regarding the python requirements installation file (as I think some of the packages are not available via direct pip installation such as GDAL,fiona..etc), let me know how things go with the requirements.txt file in the last link I sent (installing python packages), if that doesn't work I'll work out a different requirements file that you can use.

I use the following command and then receive an error message.

python3 -m pip install -r requirement.txt

Hi Romero,

After installing python3, go to the Unofficial Windows Binaries for Python Extension Packages by C.Gohlke and download the following Python wheels: (Make sure you select the version compatible with your Windows system (e.g., 64-bit) and python version(e.g., cp310 = python 3.10))

shapely
pyproj
rtree
pyzmq
GDAL
fiona
rasterio

Save all these wheels in a folder, then change directory to the folder in CMD. Type the command ” pip install FILENAME.whl ” and change “FILENAME” to the name of the package intended to be installed. Repeat steps for other packages.

After this step, Download the requirements file “requirements_edited.txt”, change directory to file’s location and type the following command in CMD and all packages listed in the file will be installed:

” pip install -r requirements_edited.txt “

I hope this solves the problem, I will try validating this with a clean installation sometime this week- it should be a matter of installing packages in the correct order considering dependencies and whether the package is available via direct pip install or not.

Cheers,
Nayef

Thanks for your reply! I wonder if there is an automatic installer for the latest v8p3 version?

Hi lihu8918,

Unfortunately an automatic installer have not been published yet- I have an unfinished structure of an automatic installer that probably I should find some time to finalise soon and share with the community.

Cheers,
Nayef

The automatic installer which is available on the official website is very old and should not be used.

A new official Windows installer based on the latest version (V8P3R1) should be published in the upcoming weeks. This installer will be kept up to date for future releases.

A Git repository providing detailed explanations on how to compile Telemac and its dependencies on Windows using Mingw64 is available from here: gitlab.pam-retd.fr/otm/wintel

This provides the best way to compile Telemac natively on Windows, without relying on POSIX emulators such as Cygwin or MSYS2.
