Failed to run Ladybug in Rhino 6. "no module named ladybug_rhino.grasshopper"

Hi there,

I’m new in Rhino 6 and Grasshopper. After I installed Ladybug in Grasshopper, it always showed “No module named ladybug_rhino.grasshopper”.
In the third part of installing the Ladybug, I closed Rhino 6 and then ran the “set_python_path”, but it always showed it was installed in Rhino 7, but I have already uninstalled Rhino 7.

Does anyone has the solution to it or has the same issue?

Please refer to this post.
