Missing dependencies in requirements.txt + excess imports in api.py

[JosephCatrambone]

A brief digression: kudos to everyone involved in this. It's a really neat project.

Issue Description: After running pip install -r requirements.txt and running python api.py, there are some dependencies which seem to be unsatisfied.

Expected Behavior: pip install -r requirements.txt should cover all required imports if possible. Running python api.py after the pip install should let the backend code run.

Observed Behavior: There are a handful of additional packages that need to be installed:

• ModuleNotFoundError: No module named 'omegaconf' (Resolve with 'pip install omegaconf')
• ModuleNotFoundError: No module named 'h11' (Resolve with 'pip install h11')
• ModuleNotFoundError: No module named 'ray' (Resolve with 'pip install ray')
• ModuleNotFoundError: No module named 'google.cloud' (Resolve with 'pip install google-cloud-storage' [!!!])
• ModuleNotFoundError: No module named 'dotenv' (Resolve by removing unused import in api.py [!!!])
• ModuleNotFoundError: No module named 'pytorch_lightning' (Resolve with 'pip install pytorch-lightning')
• ModuleNotFoundError: No module named 'einops' (Resolve with 'pip install einops')
