使用 config.toml 文件

管理员可以在启动 Driverless AI Docker 映像时编辑 config.toml 文件。此文件位于容器内的文件夹中，包括所有可能的配置选项，这些选项可以其他方式在 nvidia-docker run 命令中被指定。您可以在此文件中直接更新环境变量。Driverless AI 在从本机安装中启动时将使用更新的 config.toml 文件。Docker 用户可以在启动 Driverless AI Docker 映像时指定更新的 config.toml 文件。

请注意：请参阅 配置安全，了解更多关于配置安全性的信息。

配置覆盖链

配置引擎按照以下顺序读取和覆盖变量：

1. h2oai/config/config.toml - 此文件为不可见的内部文件。

2. config.toml - 将此文件放置于文件夹中或挂载至 Docker 容器中，并在 “DRIVERLESS_AI_CONFIG_FILE”环境变量中指定路径。

3. 密钥库文件 - 在 config.toml 文件或 “DRIVERLESS_AI_KEYSTORE_FILE” 环境变量中设置 keystore_file 参数，以指向使用 h2oai.keystore 工具生成的有效 DAI 密钥库文件。如果设置了环境变量，则config.toml 中 keystore_file 的值将被覆盖。

4. 环境变量 - 配置变量也可作为环境变量提供。这些变量必须以 DRIVERLESS_AI_ 开头，后面为全部大写的变量名称。例如，”authentication_method” 可作为 “DRIVERLESS_AI_AUTHENTICATION_METHOD” 提供。设置环境变量可覆盖密钥库文件中的值。

1. 将 config.toml 文件从 Docker 映像复制到本地文件系统。

                # 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-centos7-x86_64:1.10.1-cuda11.2.2.xx
                  -c "cp /etc/dai/config.toml /config"

2. 在 config.toml 文件中编辑相应变量。完成后，保存更改。

3. 使用 DRIVERLESS_AI_CONFIG_FILE 环境变量启动 Driverles AI。请确保这可指向已编辑的 config.toml 文件的位置，从而使软件能找到配置文件。

                docker run --runtime=nvidia \
                  --pid=host \
                  --init \

                  --shm-size=256m \

# # 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
# 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

# Whether to reduce features until model does not fail.

# Primarily useful for GPU OOM.
# If XGBoost runs out of GPU memory, this is detected, and
# (regardless of setting of skip_model_failures),
# we perform feature selection using XGBoost on subsets of features.
# The dataset is progressively reduced by factor of 2 with more models to cover all features.
# This splitting continues until no failure occurs.
# Then all sub-models are used to estimate variable importance by absolute information gain,
# in order to decide which features to include.
# Finally, a single model with the most important features
# is built using the feature count that did not lead to OOM.
# For 'auto', this option is set to 'off' when reproducible experiment is enabled,
