recommended) - d) GPU: recommended for faster training - - Note: Make sure to install compatible python and node versions and add it in PATH in system variables. - Enable pip & py launcher - - ### Steps to setup: - a) Create a virtual-environment (venv) in your project directory.( python -m venv venv for windows, or python 3.10 -m venv venv for Linux/Mac users) - b) Activate venv (venv\Scripts\activate for Windows Users and source venv/bin/activate for Mac or Linux users) - c) Upgrade pip and install core tools: - python -m pip install --upgrade pip setuptools wheel - d) The following packages: - i) Install poke-env first (this sets the correct gymnasium version) - ii) pip install poke-env - iii) pip install torch --index-url https://download.pytorch.org/whl/cpu - iv) pip
