Explanation

Some pip packages require numpy during their installation. Unfortunately, packages do not have access to other packages that are installed in the same round as each other. Therefore, the first wave installs numpy and everything that doesn't require numpy during installation. The second wave then installs the packages that do require numpy during installation.
