How to setup numpy after downloading files

Using virtualenv should work as expected. This will compile numpy on 4 CPUs and install it into the specified prefix. The two most popular open source fortran compilers are g77 and gfortran. Unfortunately, they are not ABI compatible, which means that concretely you should avoid mixing libraries built with one with another.

One relatively simple and reliable way to check for the compiler used to build a library is to use ldd on the library. If libg2c. If libgfortran. If both are dependencies, this means both have been used, which is almost always a very bad idea.

What is NumPy? NumPy can be installed with conda , with pip , with a package manager on macOS and Linux, or from source. For more detailed instructions, consult our Python and NumPy installation guide below. If you use conda , you can install NumPy from the defaults or conda-forge channels:.
