Using the config.toml File

The config.toml file is a configuration file that uses the TOML v0.5.0 file format. Administrators can customize various aspects of a Driverless AI (DAI) environment by editing the config.toml file before starting DAI.

Note

For information on configuration security, see Configuration Security.

Configuration Override Chain

The configuration engine reads and overrides variables in the following order:

  1. Driverless AI defaults: These are stored in a Python config module.

  2. config.toml - Place this file in a folder or mount it in a Docker container and specify the path in the “DRIVERLESS_AI_CONFIG_FILE” environment variable.

  3. Keystore file - Set the keystore_file parameter in the config.toml file or the environment variable “DRIVERLESS_AI_KEYSTORE_FILE” to point to a valid DAI keystore file generated using the h2oai.keystore tool. If an environment variable is set, the value in the config.toml for keystore_file is overridden.

  4. Environment variable - Configuration variables can also be provided as environment variables. They must have the prefix DRIVERLESS_AI_ followed by the variable name in all caps. For example, “authentication_method” can be provided as “DRIVERLESS_AI_AUTHENTICATION_METHOD”. Setting environment variables overrides values from the keystore file.

  1. Copy the config.toml file from inside the Docker image to your local filesystem.

                # Make a config directory
                mkdir config

                # Copy the config.toml file to the new config directory.
                docker run --runtime=nvidia \
                  --pid=host \
                  --rm \
                  --init \
                  -u `id -u`:`id -g` \
                  -v `pwd`/config:/config \
                  --entrypoint bash \
                  h2oai/dai-ubi8-x86_64:1.10.5-cuda11.2.2.xx
                  -c "cp /etc/dai/config.toml /config"
  1. Edit the desired variables in the config.toml file. Save your changes when you are done.

  2. Start DAI with the DRIVERLESS_AI_CONFIG_FILE environment variable. Ensure that this environment variable points to the location of the edited config.toml file so that the software can locate the configuration file.

                docker run --runtime=nvidia \
                  --pid=host \
                  --init \
                  --rm \
                  --shm-size=2g --cap-add=SYS_NICE --ulimit nofile=131071:131071 --ulimit nproc=16384:16384 \
                  -u `id -u`:`id -g` \
                  -p 12345:12345 \
                  -e DRIVERLESS_AI_CONFIG_FILE="/config/config.toml" \
                  -v `pwd`/config:/config \
                  -v `pwd`/data:/data \
                  -v `pwd`/log:/log \
                  -v `pwd`/license:/license \
                  -v `pwd`/tmp:/tmp \
                  h2oai/dai-ubi8-x86_64:1.10.5-cuda11.2.2.xx

# # Recipe type
# ## Recipes override any GUI settings
# - **'auto'**: all models and features automatically determined by experiment settings, toml settings, and feature_engineering_effort
# - **'compliant'** : like 'auto' except:
# - *interpretability=10* (to avoid complexity, overrides GUI or python client chose for interpretability)
# - *enable_glm='on'* (rest 'off', to avoid complexity and be compatible with algorithms supported by MLI)
# - *fixed_ensemble_level=0*: Don't use any ensemble
# - *feature_brain_level=0*(: No feature brain used (to ensure every restart is identical)
# - *max_feature_interaction_depth=1*: interaction depth is set to 1 (no multi-feature interactions to avoid complexity)
# - *target_transformer='identity'*: for regression (to avoid complexity)
# - *check_distribution_shift_drop='off'*: Don't use distribution shift between train, valid, and test to drop features (bit risky without fine-tuning)
# - **'monotonic_gbm'** : like 'auto' except:
# - *monotonicity_constraints_interpretability_switch=1*: enable monotonicity constraints
# - *self.config.monotonicity_constraints_correlation_threshold = 0.01*: see below
# - *monotonicity_constraints_drop_low_correlation_features=true*: drop features that aren't correlated with target by at least 0.01 (specified by parameter above)
# - *fixed_ensemble_level=0*: Don't use any ensemble (to avoid complexity)
# - *included_models=['LightGBMModel']*
# - *included_transformers=['OriginalTransformer']*: only original (numeric) features will be used
# - *feature_brain_level=0*: No feature brain used (to ensure every restart is identical)
# - *monotonicity_constraints_log_level='high'*
# - *autodoc_pd_max_runtime=-1*: no timeout for PDP creation in AutoDoc
# - **'kaggle'** : like 'auto' except:
# - external validation set is concatenated with train set, with target marked as missing
# - test set is concatenated with train set, with target marked as missing
# - transformers that do not use the target are allowed to fit_transform across entire train + validation + test
# - several config toml expert options open-up limits (e.g. more numerics are treated as categoricals)
# - Note: If plentiful memory, can:
# - choose kaggle mode and then change fixed_feature_interaction_depth to large negative number,
# otherwise default number of features given to transformer is limited to 50 by default
# - choose mutation_mode = "full", so even more types are transformations are done at once per transformer
# - **'nlp_model'**: Only enables NLP models that process pure text
# - **'nlp_transformer'**: Only enables NLP transformers that process pure text, while any model type is allowed
# - **'image_model'**: Only enables Image models that process pure images
# - **'image_transformer'**: Only enables Image transformers that process pure images, while any model type is allowed
# - **'unsupervised'**: Only enables unsupervised transformers, models and scorers
# - **'gpus_max'**: Maximize use of GPUs (e.g. use XGBoost, rapids, Optuna hyperparameter search, etc.)
# - **'more_overfit_protection'**: Potentially improve overfit, esp. for small data, by disabling target encoding and making GA behave like final model for tree counts and learning rate
# - **'feature_store_mojo'**: Creates a MOJO to be used as transformer in the H2O Feature Store, to augment data on a row-by-row level based on Driverless AI's feature engineering. Only includes transformers that don't depend on the target, since features like target encoding need to be created at model fitting time to avoid data leakage. And features like lags need to be created from the raw data, they can't be computed with a row-by-row MOJO transformer.
# Each pipeline building recipe mode can be chosen, and then fine-tuned using each expert settings.  Changing the
# pipeline building recipe will reset all pipeline building recipe options back to default and then re-apply the
# specific rules for the new mode, which will undo any fine-tuning of expert options that are part of pipeline building
# recipe rules.
# If choose to do new/continued/refitted/retrained experiment from parent experiment, the recipe rules are not re-applied

# way the new child experiment will use the default settings for the chosen recipe.

# _ngenes_max = 1
# _ngenes_max_by_layer = [1000, 1]

# - In the Optuna case, the scores shown in the iteration panel are the best score and trial scores.
# - Optuna mode currently only uses Optuna for XGBoost, LightGBM, and CatBoost (custom recipe).
# - If Pruner is enabled, as is default, Optuna mode disables mutations of eval_metric so pruning uses same metric across trials to compare properly.

# (continued genetic algorithm iterations)
# 4) Retrain Final Pipeline:  Like Restart but also time=0 so skips any tuning and heads straight to final model
# (assumes had at least one tuning iteration in parent experiment)
# Other use cases:
# a) Restart on different data: Use same column names and fewer or more rows (applicable to 1 - 5)
# b) Re-fit only final pipeline: Like (a), but choose time=1 and feature_brain_level=3 - 5
# c) Restart with more columns: Add columns, so model builds upon old model built from old column names (1 - 5)
# d) Restart with focus on model tuning: Restart, then select feature_engineering_effort = 3 in expert settings
