Failed to create GPU instances on H100

Hi, I am having a problem in creating GPU instances on H100 after enabling “MIG”. 1. Succesfully enabled mig with “sudo nvidia-smi mig 1”, 2. However, passing “sudo nvidia-smi mig -cgi 9,9” gives an error message “Unable to create a GPU instance on GPU 1 using profile 9: In use by another client
Failed to create GPU instances: In use by another client”. Please help!
