[nishchay47b]

Describe the bug
The ml backends are getting initialized

successfully with the command
label-studio-ml init my_ml_backend --script label_studio/ml/examples/simple_text_classifier.py and generating output
Congratulations! ML Backend has been successfully initialized in ./my_ml_backend
but after doing label-studio-ml start my_ml_backend at localhost:9090 I am getting "GET / HTTP/1.1" 404 and in the browser also I am seeing The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
I have tried the same thing in the docker container made by this Dockerfile image as well, but I am getting exactly the same error.

To Reproduce
Steps to reproduce the behavior:
Run: label-studio-ml init my_ml_backend --script label_studio/ml/examples/dummy_model.py

Expected behavior
The model page should open
Screenshots

Environment (please complete the following information):

• OS: Ubuntu
• Label Studio Version [v0.9.1.post1, 0 .8.2]

Additional context
I was trying to build a custom ml backend when I first this issue, but when I tried with the other ml backend examples given in the repo (huggingface, demo_model.py) I experienced the same thing any suggestion to help me debug this would be extremely helpful, I thought this is some compatibility issue but I ran the same thing in docker and it is still the same

@nishchay47b ML backend server doesn't have an index / page. Are you able to add ML backend to LS instance via Model page?

Sorry, I misunderstood the model page as backend server page only, it is working at 0.0.0.0:8080/model. Thank you for the response, closing this issue.
