I've received the error:

I've granted all permissions, no problem with accessing MNIST-public dataset in the same lab.
The dataset probably doesn't exist anymore.

Open courses/machine_learning/deepdive2/production_ml/labs/tpu_speed_data_pipelines.ipynb and reproduce the 403 while reading gs://flowers-public/. Check whether the bucket still exists and whether the lab's service account can list it; done means the lab can access the intended dataset or clearly points to an available replacement.
