Conda is a cross-platform, Python-agnostic binary package manager by Continuum. With exact compile flags … good luck in other package managers. Every version of each package undergoes a rigorous moderation process. Specific package to be compiled with a specific version of a packages Other package managed this simply is NOT possible. An example of this would be toĬompile all libraries with intel mkl instead or the gcc fastmath. The configuration of packages and have all package that we want thatĭepend on that package to be rebuilt. We'll nix tracks the dependencies of a given package and since numpyĬhanges all packages that are needed by pandas that depend on numpyĪlso another thing to notice here is that we have the power to modify

You'll also notice it builds a bunch of other packages. You'll notice when you run nix-shell it will startĭownloading a bunch of packages and attempting a build of numpy.

Similar approach can be used to override arbitrary binaries in While this only shows how to override a given python package set.
