Using llama-3-70B via Groq DSPy, I found it sends invalid arguments for COPRO optimizer

[ArslanS1997]

Hi, so I am using COPRO to optimize signatures and instructions, however whenever I use Llama-3-70b via groq I get this n must be at most 1 error.

Please see the attached image

I can't seem to find a way to over write it to be 1, how do I resolve this? Thanks
