# Overview

This folder contains Python scripts to create a Pub/Sub topic under
the GCP project `apache-beam-testing` and test the topic.
The created topic is `projects/apache-beam-testing/topics/Imagenet_openimage_50k_benchmark`.

# Create the topic `Imagenet_openimage_50k_benchmark`

- Create one VM to run `gcs_image_looper.py`.
  The VM `pubsub-test-do-not-delete` was already created under `apache-beam-testing`.
  Keep the script running to continuously publish data.
- You might run `gcloud auth application-default login` to get the auth.
- You might run `pip install google-cloud-core google-cloud-pubsub google-cloud-storage`.
- Must make `Imagenet_openimage_50k_benchmark` public by adding `allAuthenticatedUsers` to the Pub/Sub Subscriber role.

# Tes the topic by subscribing it

- Run `test_image_looper.py` to check whether you could get any data.
