Quickstart

To get started with Forte2, you can either download it from conda-forge, or compile it from source.

Install with conda

If you have a conda distribution installed (e.g., miniconda), you can obtain Forte2 from conda-forge:

$ conda install -c conda-forge forte2

Compile from source

If your platform is not supported by the current conda-forge Forte2 package, or if you want to develop Forte2, follow these steps to compile Forte2 from source:

1. Clone the Forte2 repository from GitHub:

   $ git clone git@github.com:evangelistalab/forte2.git
   $ cd forte2
   

2. Install the required dependencies in environment.yml. You can most easily do this in a new conda environment:

   $ conda env create -f environment.yml
   

3. Build the project:

   $ pip install --no-build-isolation -ve .
   

4. Run the quick tests:

   $ pytest -m "not slow"
