| Installation | The documentation says to install fastai on a machine with `pip install fastai` and recommends installing PyTorch first. | JAX uses the `jax` Python package and `jaxlib`, which contains compiled binaries with different builds for operating systems and accelerators. |
| Support | The fast.ai forums include a category for help installing and using the fastai library for users at any level. | The installation guide directs users with problems using prebuilt wheels to the JAX GitHub issue tracker. |
