How to load tf.keras model directly from cloud bucket?

Question

I try to load tf.keras model direcly from cloud bucket but I can't see easy wat to do it. I would like to load whole model structure not only weights.

I see 3 possible directions:

1. Is posssible to load keras model directly from Google cloud bucket? Command tf.keras.model.load_model('gs://my_bucket/model.h5') doesn't work

2. I tried to use tensorflow.python.lib.ii.file_io but I don't know how to load this as model.

3. I copied model to local directory by gsutil cp command but I don't know how to wait until operation will be complete. tf try to load model before download operation is complete so the errors occurs

I will be thankful for any sugestions.

1. Load the file from gs storage

from tensorflow.python.lib.io import file_io
model_file = file_io.FileIO('gs://mybucket/model.h5', mode='rb')

2. Save a temporary copy of the model locally

temp_model_location = './temp_model.h5'
temp_model_file = open(temp_model_location, 'wb')
temp_model_file.write(model_file.read())
temp_model_file.close()
model_file.close()

3. Load model saved locally

model = tf.keras.models.load_model(temp_model_location)
