Hi again,

I wrote it also in github, but I have trouble loading the model from the url provided in this github issue [PolyAI Models - model.tar.gz - No Longer Available? · Issue #6806 · RasaHQ/rasa · GitHub](https://github.com/RasaHQ/rasa/issues/6806), I tried changing the configuration file, and the url in convert\_tokenizer.py but still. Then I tried to load it as tensorflow hub module but also get an error. Any help?

```
import tensorflow_hub as tfhub

model_url = "https://github.com/connorbrinton/polyai-models/releases/download/v1.0/model.tar.gz"
t = tfhub.load(model_url)

```

Results in

`tensorflow.python.framework.errors_impl.NotFoundError: Op type not registered 'WordpieceTokenizeWithOffsets' in binary running on iti-722. Make sure the Op and Kernel are registered in the binary running in this process. Note that if you are loading a saved graph which used ops from tf.contrib, accessing (e.g.) `tf.contrib.resampler` should be done before importing the graph, as contrib ops are lazily registered when the module is first accessed.`

```
import tensorflow_hub as tfhub

model_url = "https://github.com/connorbrinton/polyai-models/releases/tag/v1.0"
tfhub.load(model_url)

```

results in

`OSError: https://github.com/connorbrinton/polyai-models/releases/tag/v1.0 does not appear to be a valid module.`
