AttributeError: module 'opennmt.models.catalog' has no attribute 'NMTSmall'

I’ve followed OpenNMT-tf tutorial on this site

until ‘make data.yml’ process.

then I followed script on COLAB, because I would like to know
how do this code ,tf.estimator.train_and_evaluate, work.

from __future__ import print_function
import tensorflow as tf
from opennmt.runner import Runner
from opennmt.config import load_model
from opennmt.config import load_config

config = load_config(['/content/OpenNMT_COLAB_Practice/Data.yml'])

model = load_model(config["model_dir"],
                   model_name= 'NMTSmall',

then I got this message

AttributeError                            Traceback (most recent call last)

AttributeError: module 'opennmt.models.catalog' has no attribute 'NMTSmall'

I can’t understand why I got AttributeError, because ‘NMTSmall’ model is in the ‘’
and I don’t know how to fix it

This is not an official OpenNMT-tf tutorial, so you should raise the issue in the tutorial repository.

Here’s the fix though:
