Train and Deploy LightGBM model

training iris classifier model

Run the mock python training code

pip install -r examples/lightgbm/requirements.txt 
python examples/lightgbm/train_model.py

The output will be a model created on the project "serving examples", by the name "train lightgbm model"

setting up the serving service

  1. Create serving Service: clearml-serving create --name "serving example" (write down the service ID)

  2. Create model endpoint:

clearml-serving --id <service_id> model add --engine lightgbm --endpoint "test_model_lgbm" --preprocess "examples/lightgbm/preprocess.py" --name "train lightgbm model - lgbm_model" --project "serving examples"

Or auto-update

clearml-serving --id <service_id> model auto-update --engine lightgbm --endpoint "test_model_auto" --preprocess "examples/lightgbm/preprocess.py" --name "train lightgbm model - lgbm_model" --project "serving examples" --max-versions 2

Or add Canary endpoint

clearml-serving --id <service_id> model canary --endpoint "test_model_auto" --weights 0.1 0.9 --input-endpoint-prefix test_model_auto

  1. If you already have the clearml-serving docker-compose running, it might take it a minute or two to sync with the new endpoint.

Or you can run the clearml-serving container independently docker run -v ~/clearml.conf:/root/clearml.conf -p 8080:8080 -e CLEARML_SERVING_TASK_ID=<service_id> clearml-serving:latest

  1. Test new endpoint (do notice the first call will trigger the model pulling, so it might take longer, from here on, it's all in memory): curl -X POST "http://127.0.0.1:8080/serve/test_model_lgbm" -H "accept: application/json" -H "Content-Type: application/json" -d '{"x0": 1, "x1": 2, "x2": 3, "x3": 4}'

Notice: You can also change the serving service while it is already running! This includes adding/removing endpoints, adding canary model routing etc.
