Numba

Numba (https://numba.pydata.org) is an optional library which makes PyAutoGalaxy run a lot faster, which we strongly recommend all users have installed.

Certain functionality (pixelized source reconstructions, linear light profiles) is disabled without numba installed because it will have too slow run-times.

However, some users have experienced difficulties installing numba, meaning they have been unable to try out PyAutoGalaxy and determine if it the right software for them, before committing more time to installing numba successfully.

For this reason, numba is an optional installation, so that users can easily experiment and learn the basic API.

If you do not have numba installed, you can do so via pip as follows:

pip install numba
