No application file

Hello,
I am trying to host a gradio app. https://huggingface.co/spaces/chandrakalagowda/texttoimg

The python code runs locally and launches the gradio app.

When I run ‘gradio deploy’ in the terminal, the files are uploaded to huggingface spaces, however, the spaces does not recognise my app.py file.

It seems to suggest that there is no application file. please help.
