FastText cannot be opened for loading from bucket

Question

I downloaded fasttext model lid.176.bin. If I run my code locally with model in folder everything works fine. But I need to run it in GC, so, I uploaded model into bucket and changed path to model from local to gs bucket and got an error: ValueError: gs://models/fasttext-model/lid.176.bin cannot be opened for loading! How can I use model from bucket?

path_to_pretrained_model = 'gs://models/fasttext-model/lid.176.bin'
fasttext_model = fasttext.load_model(path_to_pretrained_model)

This function from Google Documentation helps me to solve the problem

from google.cloud import storage


def download_blob(bucket_name, source_blob_name, destination_file_name):
    """Downloads a blob from the bucket."""
    # bucket_name = "your-bucket-name"
    # source_blob_name = "storage-object-name"
    # destination_file_name = "local/path/to/file"

    storage_client = storage.Client()

    bucket = storage_client.bucket(bucket_name)

    # Construct a client side representation of a blob.
    # Note `Bucket.blob` differs from `Bucket.get_blob` as it doesn't retrieve
    # any content from Google Cloud Storage. As we don't need additional data,
    # using `Bucket.blob` is preferred here.
    blob = bucket.blob(source_blob_name)
    blob.download_to_filename(destination_file_name)

    print(
        "Blob {} downloaded to {}.".format(
            source_blob_name, destination_file_name
        )
    )
