Numpy in rhino 7

Hi, is it possible to use numpy in rhino 7?

Not directly. That was the huge leap forward with Rhino 8.

The old way of using Numpy and C-extension modules from PyPI, was by calling out to some external CPython process that has them installed.

It’s all still possible. But it was never trouble free, e.g. with some plug-ins installing Python 3 Numpy versions into the system’s Iron Python 2 paths. So it will be far easier to update Rhino to v8.
