Install the Python library:

pip install replicate

Then, run this to create a training with fofr/sdxl-mario-kart:c46d8853 as the base model:

import replicate

training = replicate.trainings.create(
  version="fofr/sdxl-mario-kart:c46d88533b10df14e459bc18e2908c12943ab8ace0ae22d93db9a955bd7ed302",
  input={
    ...
  },
  destination=f"{username}/<destination-model-name>"
)

print(training)

curl -s -X POST \
-d '{"destination": "{username}/<destination-model-name>", "input": {...}}' \
  -H "Authorization: Bearer $REPLICATE_API_TOKEN" \
