The steps are likely to remain very similar for other versions of Ubuntu OS, and also not expected to vary significantly for other Linux distributions. In the latter case, you will find on the Internet about how to carry out the equivalent of the tasks demonstrated here using Ubuntu OS. Also, the tutorial will focus only on Python 3, as Python 2 has now been deprecated. It is recommended to use Python version 3.6 or higher. I would be using Python 3.8.10 in this tutorial, as it is the default version provided with Ubuntu 20.04.

64 -Having multiple versions of Python on your system can produce issues while installing NEST. The method shown below will install NEST for the default version of Python provided by your Ubuntu OS. E.g. for Ubuntu 18.04 this might be Python 3.6.9 and for Ubuntu 20.04 it will likely be 3.8.10. If you wish to associate the NEST installation with a different Python version installed on your system, please refer the NEST installation instructions to do so on their website.
