 Users which don't want to install python with all dependencies can use [Portable Python](http://portablepython.com) (version 2.x). Then, just extract DEVSimPy archive and edit the devsimpy.py file with [PyScripter](https://sourceforge.net/projects/pyscripter/) to execute it. Users can also execute DEVSimPy through the conda env file loaded using the [conda_devsimpy_env.yml](https://github.com/capocchi/DEVSimPy-site/raw/gh-pages/conda_devsimpy_env.yml) file (available from the [DEVSimPy-site](https://github.com/capocchi/DEVSimPy-site) repository).

 An archive of a conda environment which includes all the binaries of the packages needed for the DEVSimPy environment is available here: [py38.tar.gz](https://mycore.core-cloud.net/index.php/s/5nNgyvwps6O2kUy). This is useful when you want to reproduce a compatible environment for DEVSimPy and avoid all installation and dependencies requirement.
