I’m pretty sure these libraries are not going to work on Rhino 6 and there hasn’t been much of any mention of these libraries being updated to support 64 bit. The best two options that I can think of at the moment would be to either
- call python in an external process and wait for a result
- let us know exactly what functionality you need from these libraries so we can see if there is anything we can expose in Rhino’s SDK to provide equivalent functionality.
