Hello all,
I was able to solve this error.
- The error “File is not a zip file” was probably due to a poor internet connection. The same problem was asked and addressed here, incase anyone lands into the same soup.
- My original problem of “Failed to import ladybug_rhino: Cannot import name recommended_processor_count” was not getting solved even after Uninstalling and reinstalling. What turned out was- I reinstalled Rhino with “Run as administrator” and instead of installing it in C:\Program Files\Rhino 6 I installed it in C:\Rhino 6. Now this doesnt seem to be a proper solution and Im not sure why it happened this time, but this technique worked for me. It’s sort of a fix but worked for me. Anyway thanks @chris for guiding and hinting me in the right direction.
