The SalvusMesh, SalvusFlow, and SalvusOpt packages are part of a single Salvus Python module.
Please note that Python is not necessary for SalvusCompute and we don't recommend installing the Python packages on an HPC system or other big cluster by default.
Salvus currently requires an installation of Python 3.7. There are different possibilities to achieve this and most should work fine. We recommend to install the latest Miniconda distribution and subsequent dependencies using the package manager Mamba.
Please note that the use of
mamba is optional, and that the user is
responsible for complying with the licenses provided by any Python package
If you follow our recommended installation procedure you will first install
Miniconda and then create a new python environment using
mamba in which to
finally install Salvus and all dependencies. In case this is new to you there
are a lot of guides and instructions around, e.g. this
Assuming you are following our recommendations of using
mamba, please use this
environment.yml file. It describes a python envionment
containing all dependencies required to run Salvus. Additionally it contains the
Jupyter project which we recommend as an interface to Salvus.
After installing Miniconda and
mamba just run:
# Download the file. If that does not work just right click -> Save Link As ... # on the link in the previous paragraph. curl https://mondaic.com/environment.yml -o environment.yml # Create a new environment with all required dependencies. mamba env create -n salvus -f environment.yml # Activate that environment. conda activate salvus # Activating this plug-in results in nicer error traces in the notebooks. jupyter nbextension enable skip-traceback/main
By now there should be some indication in your shell that you have an active Salvus python environment. Remember to always activate it, otherwise Salvus will not be available.
