The issue when try to start a tpu-vm

[sglucas]

Hi @skye

When I try to start a tpu-vm v3-32 with this command:

gcloud alpha compute tpus tpu-vm create v3-32 --zone europe-west4-a --accelerator-type v3-32 --version v2-alpha

it occurs this error:

ERROR: (gcloud.alpha.compute.tpus.tpu-vm.create) { "code": 9, "message": "Insufficient reserved capacity. Contact customer support to increase your reservation. [EID: 0x72a13ef4f9caeaa2]" }

However I can successfully start a tpu-vm v3-128.

It could be better if you can give me some advice

I note this issue isn't related to JAX specifically and would probably be best addressed through Cloud TPU support channels.

Thanks for your reply.

May I ask how to contact cloud TPU support?

Hi @sglucas, do you have a reserved capacity or you are using on-demand quota? were you able to create v3-128 right after you failed to create v3-32? This type of error usually occurs when there is no capacity available.

[sglucas]

Yes, I can create v3-128 now but v3-32 is still not available. So I think I still have quota to start v3-32.

Did you delete v3-128 before retrying v3-32? You can reach out to [email protected]. In the email please include your project ID, the full error message you get when trying to create the tpu. Hope this helps.

Also please refer to this guide for choosing a version for accelerator type https://cloud.google.com/tpu/docs/supported-tpu-configurations#jax
--version v2-alpha is very old and deprecated.

Thanks for your answer. I try to use other version and I still can not start v3-32.

Best,
Lucas
