Hint: use -a/--all to see all accelerators (including non-common ones) and pricing.
Note: No GPUs found in Kubernetes cluster. If your cluster contains GPUs, make sure nvidia.com/gpu resource is available on the nodes and the node labels for identifying GPUs (e.g., skypilot.co/accelerator) are setup correctly. To further debug, run: sky check
