I'm using a free trial account for TPU training my deep learning models with my billing account enabled and I still have more than $100 promotional credits in my account. 2 days ago my preemptible TPU was "preemtibled" in the middle of a training session.
Since then I have tried multiple times to create a new TPU in different regions but I always got the following error:
Creating TPU node "node-1" failed. Error: APPLICATION_ERROR;google.cloud.tpu.v1/Tpu.CreateNode;Quota limit 'TPUV2sPodPerProjectPerRegionForTPUAPI,TPUV2sPodPerProjectPerZoneForTPUAPI' has been exceeded.

I thought it has something to do with my quotas so I checked my quotas and I saw my "Preemptible TPU v3 cores per project per region" and "Preemptible TPU v3 cores per project per zone" are all 0. Is this the reason I cannot create new TPUs? If this is the reason then how did I manage to create my old TPU? And most importantly, how do I fix this?
