A project to experiment with and validate semantics for KerML and SysML v2. Running core semantics and interpreting models is a foundational capability for any modeling software.

git clone https://github.com/bjorncole/pymbe.git
cd pymbe

or stick to conda if you like... just change mamba to conda in the instructions below.

If you have anaconda or miniconda, install mamba (it's faster and better than conda):

conda install mamba

You may need to specify the channel: conda install -c conda-forge mamba

If you don't have anaconda or miniconda, just get Mambaforge.

This will be an environment that has anaconda-project and some other dependencies to run the development commands.

For added consistency, use the provided .condarc file:

CONDARC=.github/.condarc        # linux
set CONDARC=.github\.condarc    # windows

conda env create -f .github/environment.yml -p envs/pymbe

You don't have to repeat these steps unless you delete your base environment.

You will have to activate the base environment to make sure you are using the appropriate version. You will have to do this every time you open a new shell (e.g., windows command prompt, a linux bash) unless you automate the activation of the environment.

conda activate envs/pymbe

If you are going to be changing the anaconda-project environments, it is a good idea to make anaconda-project use mamba instead of conda (it is much faster)

Remember you will have to do this when you start your shell unless you set these environment variables permanently.

CONDA_EXE=mamba        # linux
set CONDA_EXE=mamba    # windows

Remember to set your .condarc path as explained in Step 3.

This will install the non-packaged dependencies and pymbe in editable mode.

anaconda-project run setup

You can then get a running instance of JupyterLab by running:

anaconda-project run lab

Remember if you open a new shell, you will have to activate your base environment as explained in Step 4.

Copy the URL where JupyterLab is running into your preferred browser, and you should be good to go!

You can interact with the SysML v2 data using widgets, as illustrated below:
