Although I have GPU quota =4 (all region), it's really frustrating to find a region that I can create multiple GPU VMs. "us-central1" was the only region I could start any GPU VM, and all other attempts failed with "not enough resource". Even in "us-central1", the instance group with autoscaling never create >1 VMs, and always got "The zone currently does have not enough resources for your instance group. Please wait for resources to free up or consider moving to another region or zone."
Is there general shortage of T4 GPU across GCP? Or is it something I configured wrong?
