I'm trying to install numpy using this. This link opens with these instructions:
These instructions describe how to build NumPy and SciPy libraries from source.
If you just want to use NumPy or SciPy, install pre-built binaries as described in Installing the SciPy Stack.
If I'm not wrong, to "build" generally means to compile files into machine readable ones and then group them into an executable. From the expression "build from source", I infer that, firstly, there are multiple ways to build a file and, secondly, this particular way builds the file from its source code.
If this is true, is a pre-built binary a set of files that have already been compiled?
