Hi, users are unable to run 21cmfast due to dependency conflict with sphinx-rtd-theme package.
As shown in the full dependency graph of 21cmfast, pillow requires sphinx-rtd-theme (the latest version), while coverage requires sphinx-rtd-theme (==0.2.4).
According to pip's "first found wins" installation strategy, sphinx-rtd-theme==0.5.0 is the actually installed version. However, sphinx-rtd-theme==0.5.0 does not satisfy sphinx-rtd-theme (==0.2.4).
