ModuleNotFoundError: No module named 'mmk2_sdk'

When I run the policy evaluation code
`python3 policies/infer.py act -tn mmk2_round1_pick -mts 200 -ts 20250312-030825 -rn task.py`
I got this error
This looks like the official SDK for mmk2, can you tell me where to download it and how to install it?
