TypeError in TTS demo
### Describe the bug

Looking to demo a text-to-speech model using the [fastspeech2 checkpoint](https://huggingface.co/facebook/fastspeech2-en-ljspeech) from the HF hub as follows:
```python
import gradio as gr

gr.Interface.load("huggingface/facebook/fastspeech2-en-ljspeech").launch();
```
This yields the following demo: https://45412.gradio.app/
However, when I try and run the demo with any sort of input I just get `ERROR`. The demo should work as it does on the fastspeech2 model card: https://huggingface.co/facebook/fastspeech2-en-ljspeech
