# Step 1, load the data
# Probably, we want to see just a folder with openai batch input jsonls, plus the batch output jsonls
# TODO: Figure out hyperparameters for image sizing
# Step 2. Load those prompts through and do a forward pass to calculate the loss

# Step 3. Add hugging face accelerate for training

# Step 4. Checkpointing code, both saving and reloading to restart

# Step 5. Move over from interactive session to gantry launch script
