Hello Vignesh,
Azure Container Instances (ACI) supports GPU SKU V100 for Central India as per:
https://learn.microsoft.com/en-us/azure/container-instances/container-instances-region-availability#linux-container-groups
https://learn.microsoft.com/en-us/azure/container-instances/container-instances-gpu#region-availability
I can confirm that I just tried from my side to create one ACI in Central India with GPU and I get the same message. Taking in consideration the message and the fact that GPU usability is for the moment a preview feature for ACI (there is no guarantee about runtime or availability) , it is most probably the fact that there are no GPU resources available in Central India region. I tried in West Europe, and I have the ability to use GPU for ACI.
I would recommend you one or more of the following approaches:
1 - Create your ACI with GPU in another region. Please refer to the above links to understand the regions where ACI supports GPU
2 - Wait some time hopping some capacity will free-up in Central India
3 - Open a support request to report your issue and get more insights of why it doesn't work right now to create ACI with GPU in Central India.
I hope this is helpful. If any clarification needed, let me know and I will do my best to answer.
