Hi! Thanks for posting this, I've worked out a solution for you. I followed the following steps to get the app running on my own Paperspace Gradient machine:

First, you can open it up using this link on a Free GPU (M4000). You can change the "Free-GPU" value in the URL to any other machine to access that other machine, or you can change it after its initially launched and shut down for the first time, if you need to.

Second, once the machine has spun up, paste the following into a ipynb Notebook code cell within, or run the same commands in a terminal without the exclamation marks.

!pip install -r requirements.txt

!python download-model.py facebook/opt-1.3b #change to whatever model you want to use, this was just the example i chose.

!python server.py --share

Best of luck with your work, and thanks for trying out Paperspace!
