You can proceed by either installing the PlayMolecule python API to the system python installation or to a Miniconda or Anaconda installation. We recommend installing the package into a new Miniconda environment to prevent compatibility issues with any other python packages already installed on your system.
Head over to https://docs.conda.io/en/latest/miniconda.html and download the latest Python 3.X package for your operating system. You can then follow the installation instructions for Miniconda here: https://conda.io/projects/conda/en/latest/user-guide/install/index.html.
Once Miniconda is installed you should have the conda command available in your command line. You can now create a new conda environment called for example playmolecule (you can call it whatever you want) with python version 3.6 with the following command:
conda create -n playmolecule python=3.6 ipython
Next, activate that environment so that you can use it and install any further packages using:
conda activate playmolecule
Once the environment playmolecule is active, you can install the package using the command pip install playmolecule
