Google Cloud TPU

1.26.0 verified Sat May 09 auth: no python

Client library for the Google Cloud TPU API, which allows management of Cloud TPU resources. Current version 1.26.0, requires Python >=3.9. Released as part of google-cloud-python monorepo with regular weekly releases.

pip install google-cloud-tpu

Common errors

error ModuleNotFoundError: No module named 'google.cloud.tpu' ↓

cause The package is not installed or import path is incorrect.

fix

Run 'pip install google-cloud-tpu' and import as 'from google.cloud import tpu'.

error AttributeError: module 'google.cloud.tpu' has no attribute 'TpuClient' ↓

cause Importing from old or incorrect submodule (e.g., google.cloud.tpu_v1).

fix

Use 'from google.cloud import tpu' and then 'client = tpu.TpuClient()'.

error google.api_core.exceptions.PermissionDenied: 403 The caller does not have permission ↓

cause Incorrect or missing authentication credentials, or the service account lacks TPU permissions.

fix

Set GOOGLE_APPLICATION_CREDENTIALS to a service account key with roles/tpu.admin or use ADC with appropriate scopes.

Warnings

deprecated The `google-cloud-tpu` library uses the v2alpha1 API by default; some resource fields may be unstable. For production, pin to a specific API version (e.g., v2). ↓

fix Use `from google.cloud.tpu_v2 import TpuClient` instead of the generic namespace.

gotcha Do not use `google.cloud.tpu_v1` – it is outdated and does not reflect current TPU features. Prefer v2 or v2alpha1. ↓

fix Use `from google.cloud import tpu` or `from google.cloud.tpu_v2 import TpuClient`.

breaking Python 3.9 support was dropped after version 1.21.0. Ensure you use Python >=3.10 for versions >=1.22.0. ↓

fix Upgrade Python to 3.10 or later, or pin to google-cloud-tpu==1.21.0.

Install

pip install google-cloud-tpu[googleapis-common-protos]

Imports

TpuClient
wrong
```
from google.cloud.tpu_v1 import TpuClient
```
correct
```
from google.cloud import tpu
```
Use the generic namespace package; specific versions like tpu_v1 are internal and may change.

Quickstart

Initialize TPU client and list nodes in a project/location. Requires authentication via Application Default Credentials or service account.

from google.cloud import tpu

client = tpu.TpuClient()
parent = f"projects/{os.environ.get('PROJECT_ID', '')}/locations/us-central1"
nodes = client.list_nodes(parent=parent)
print(nodes)
