 In 2018, Francesco started neuroseries, a Python package built on Pandas. It was quickly adopted in Adrien's lab, especially by Guillaume Viejo, a postdoc in the lab. Gradually, the majority of the lab was using it and new functions were constantly added.
 In 2021, Guillaume and other trainees in Adrien's lab decided to fork from neuroseries and started *pynapple*. The core of pynapple is largely built upon neuroseries. Some of the original changes to TSToolbox made by Luke were included in this package, especially the *time_support* property of all ts/tsd objects.

 Multiple python packages exist for high-performance computing. Internally, pynapple makes extensive use of [numba](https://numba.pydata.org/) for accelerating some functions. Numba is a stable package that provide speed gains with minimal installation issues when running on CPUs.
 
 Another high-performance toolbox for numerical analysis is
