System configuration¶
exclusive_mode¶
Exclusive level of access to node resources (String) (Expert Setting)
Default value 'safe'
safe: assume might be running another experiment on same node moderate: assume not running any other experiments or tasks on same node, but still only use physical core count max: assume not running anything else on node at all except the experiment If multinode is enabled, this option has no effect, unless worker_remote_processors=1 when it will still be applied. Each exclusive mode can be chosen, and then fine-tuned using each expert settings. Changing the exclusive mode will reset all exclusive mode related 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 exclusive mode rules. If choose to do new/continued/refitted/retrained experiment from parent experiment, all the mode rules are not re-applied and any fine-tuning is preserved. To reset mode behavior, one can switch between ‘safe’ and the desired mode. This way the new child experiment will use the default system resources for the chosen mode.
max_cores¶
Number of cores to use (0 = all) (Number) (Expert Setting)
Default value 0
Max number of CPU cores to use for the whole system. Set to <= 0 to use all (physical) cores.
If the number of worker_remote_processors is set to a value >= 3, the number of cores will be reduced
by the ratio (worker_remote_processors_max_threads_reduction_factor * worker_remote_processors)
to avoid overloading the system when too many remote tasks are processed at once.
One can also set environment variable ‘OMP_NUM_THREADS’ to number of cores to use for OpenMP
(e.g., in bash: ‘export OMP_NUM_THREADS=32’ and ‘export OPENBLAS_NUM_THREADS=32’).
small_data_recipe_work¶
Small data work (String) (Expert Setting)
Default value 'auto'
Whether to treat data as small recipe in terms of work, by spreading many small tasks across many cores instead of forcing GPUs, for models that support it via static var _use_single_core_if_many. ‘auto’ looks at _use_single_core_if_many for models and data size, ‘on’ forces, ‘off’ disables.
max_fit_cores¶
Maximum number of cores to use for model fit (Number) (Expert Setting)
Default value 10
Control maximum number of cores to use for a model’s fit call (0 = all physical cores >= 1 that count). See also tensorflow_model_max_cores to further limit TensorFlow main models.
parallel_score_max_workers¶
Maximum number of cores to use for model parallel scoring (Number) (Expert Setting)
Default value 0
Control maximum number of cores to use for a scoring across all chosen scorers (0 = auto)
use_dask_cluster¶
If full dask cluster is enabled, use full cluster (Boolean) (Expert Setting)
Default value True
Whether to use full multinode distributed cluster (True) or single-node dask (False). In some cases, using entire cluster can be inefficient. E.g. several DGX nodes can be more efficient if used one DGX at a time for medium-sized data.
max_predict_cores¶
Maximum number of cores to use for model predict (Number) (Expert Setting)
Default value 0
Control maximum number of cores to use for a model’s predict call (0 = all physical cores >= 1 that count)
max_predict_cores_in_dai¶
Maximum number of cores to use for model transform and predict when doing MLI and AutoDoc. (Number) (Expert Setting)
Default value -1
- Control maximum number of cores to use for a model’s transform and predict call when doing operations inside DAI-MLI GUI and R/Py client.
The main experiment and other tasks like MLI and autoreport have separate queues. The main experiments have run at most worker_remote_processors tasks (limited by cores if auto mode), while other tasks run at most worker_local_processors (limited by cores if auto mode) tasks at the same time, so many small tasks can add up. To prevent overloading the system, the defaults are conservative. However, if most of the activity involves autoreport or MLI, and no model experiments are running, it may be safe to increase this value to something larger than 4. -1 : Auto mode. Up to physical cores divided by 4, up to maximum of 10.
0 : all physical cores >= 1: that count).
batch_cpu_tuning_max_workers¶
Tuning workers per batch for CPU (Number) (Expert Setting)
Default value 0
Control number of workers used in CPU mode for tuning (0 = socket count -1 = all physical cores >= 1 that count). More workers will be more parallel but models learn less from each other.
cpu_max_workers¶
Num. workers for CPU training (Number) (Expert Setting)
Default value 0
Control number of workers used in CPU mode for training (0 = socket count -1 = all physical cores >= 1 that count)
assumed_simultaneous_dt_forks_munging¶

Default value 0
Maximum parallel workers for final model building. 0 means automatic, >=1 means limit to no more than that number of parallel jobs. Can be required if some transformer or model uses more than the expected amount of memory. Ways to reduce final model building memory usage, e.g. set one or more of these and retrain final model: 1) Increase munging_memory_overhead_factor to 10 2) Increase final_munging_memory_reduction_factor to 10 3) Lower max_workers_final_munging to 1 4) Lower max_workers_final_base_models to 1 5) Lower max_cores to, e.g., 1/2 or 1/4 of physical cores.
max_workers_final_munging¶
Max. workers for final per-model munging (Number) (Expert Setting)
Default value 0
Maximum parallel workers for final per-model munging. 0 means automatic, >=1 means limit to no more than that number of parallel jobs. Can be required if some transformer uses more than the expected amount of memory.
min_dt_threads_munging¶
min_dt_threads_munging (Number) (Expert Setting)
Default value 1

Default value 1
Like min_datatable (and OpenMP)_threads_munging but for final pipeline munging

num_gpus_per_experiment¶
#GPUs/Experiment (-1 = autodetect or all) (Number) (Expert Setting)
Default value -1
Number of GPUs to use per experiment for training task. Set to -1 for all GPUs. An experiment will generate many different models. Currently num_gpus_per_experiment!=-1 disables GPU locking, so is only recommended for single experiments and single users. Ignored if GPUs disabled or no GPUs on system. More info at: https://github.com/NVIDIA/nvidia-docker/wiki/nvidia-docker#gpu-isolation In multinode context when using dask, this refers to the per-node value. For ImageAutoModel, this refers to the total number of GPUs used for that entire model type, since there is only one model type for the entire experiment. E.g. if have 4 GPUs and want 2 ImageAuto experiments to run on 2 GPUs each, can set num_gpus_per_experiment to 2 for each experiment, and each of the 4 GPUs will be used one at a time by the 2 experiments each using 2 GPUs only.
min_num_cores_per_gpu¶
Num Cores/GPU (Number) (Expert Setting)
Default value -2
- Number of CPU cores per GPU. Limits number of GPUs in order to have sufficient cores per GPU.
Set to -1 to disable, -2 for auto mode. In auto mode, if lightgbm_use_gpu is ‘auto’ or ‘off’, then min_num_cores_per_gpu=1, else min_num_cores_per_gpu=2, due to lightgbm requiring more cores even when using GPUs.
num_gpus_per_model¶
#GPUs/Model (-1 = all) (Number) (Expert Setting)
Default value 1
Number of GPUs to use per model training task. Set to -1 for all GPUs. For example, when this is set to -1 and there are 4 GPUs available, all of them can be used for the training of a single model. Only applicable currently to image auto pipeline building recipe or Dask models with more than one GPU or more than one node. Ignored if GPUs disabled or no GPUs on system. For ImageAutoModel, the maximum of num_gpus_per_model and num_gpus_per_experiment (all GPUs if -1) is taken. More info at: https://github.com/NVIDIA/nvidia-docker/wiki/nvidia-docker#gpu-isolation In multinode context when using Dask, this refers to the per-node value.
num_gpus_for_prediction¶
Num. of GPUs for isolated prediction/transform (Number) (Expert Setting)
Default value 0
Number of GPUs to use for predict for models and transform for transformers when running outside of fit/fit_transform. -1 means all, 0 means no GPUs, >1 means that many GPUs up to visible limit. If predict/transform are called in same process as fit/fit_transform, number of GPUs will match, while new processes will use this count for number of GPUs for applicable models/transformers. Exception: TensorFlow, PyTorch models/transformers, and RAPIDS predict on GPU always if GPUs exist. RAPIDS requires python scoring package be used also on GPUs. In multinode context when using Dask, this refers to the per-node value.
gpu_id_start¶
GPU starting ID (0..visible #GPUs - 1) (Number) (Expert Setting)
Default value -1
Which gpu_id to start with -1 : auto-mode. E.g. 2 experiments can each set num_gpus_per_experiment to 2 and use 4 GPUs If using CUDA_VISIBLE_DEVICES=… to control GPUs (preferred method), gpu_id=0 is the first in that restricted list of devices. E.g. if CUDA_VISIBLE_DEVICES=’4,5’ then gpu_id_start=0 will refer to the device #4. E.g. from expert mode, to run 2 experiments, each on a distinct GPU out of 2 GPUs: Experiment#1: num_gpus_per_model=1, num_gpus_per_experiment=1, gpu_id_start=0 Experiment#2: num_gpus_per_model=1, num_gpus_per_experiment=1, gpu_id_start=1 E.g. from expert mode, to run 2 experiments, each on a distinct GPU out of 8 GPUs: Experiment#1: num_gpus_per_model=1, num_gpus_per_experiment=4, gpu_id_start=0 Experiment#2: num_gpus_per_model=1, num_gpus_per_experiment=4, gpu_id_start=4 E.g. Like just above, but now run on all 4 GPUs/model Experiment#1: num_gpus_per_model=4, num_gpus_per_experiment=4, gpu_id_start=0 Experiment#2: num_gpus_per_model=4, num_gpus_per_experiment=4, gpu_id_start=4 If num_gpus_per_model!=1, global GPU locking is disabled (because underlying algorithms don’t support arbitrary gpu ids, only sequential ids), so must setup above correctly to avoid overlap across all experiments by all users More info at: https://github.com/NVIDIA/nvidia-docker/wiki/nvidia-docker#gpu-isolation Note that GPU selection does not wrap, so gpu_id_start + num_gpus_per_model must be less than number of visibile GPUs
allow_reduce_features_when_failure¶
Whether to reduce features when model fails (String) (Expert Setting)
Default value 'auto'
Whether to reduce features until model does not fail. Currently for non-dask XGBoost models (i.e. GLMModel, XGBoostGBMModel, XGBoostDartModel, XGBoostRFModel), during normal fit or when using Optuna. 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, because the condition of running OOM can change for same experiment seed. Reduction is only done on features and not on rows for the feature selection step.
reduce_repeats_when_failure¶
Number of repeats for models used for feature selection during failure recovery. (Number) (Expert Setting)
Default value 1
With allow_reduce_features_when_failure, this controls how many repeats of sub-models used for feature selection. A single repeat only has each sub-model consider a single sub-set of features, while repeats shuffle which features are considered allowing more chance to find important interactions. More repeats can lead to higher accuracy. The cost of this option is proportional to the repeat count.
fraction_anchor_reduce_features_when_failure¶
Fraction of features treated as anchor for feature selection during failure recovery. (Float) (Expert Setting)
Default value 0.1
With allow_reduce_features_when_failure, this controls the fraction of features treated as an anchor that are fixed for all sub-models. Each repeat gets new anchors. For tuning and evolution, the probability depends upon any prior importance (if present) from other individuals, while final model uses uniform probability for anchor features.
xgboost_reduce_on_errors_list¶
Errors from XGBoost that trigger reduction of features (List) (Expert Setting)
Default value ['Memory allocation error on worker', 'out of memory', 'XGBDefaultDeviceAllocatorImpl', 'invalid configuration argument', 'Requested memory']

lightgbm_use_gpu¶
Whether to use GPUs for LightGBM (String) (Expert Setting)
Default value 'auto'
- LightGBM does not significantly benefit from GPUs, unlike other tools like XGBoost or Bert/Image Models.
Each experiment will try to use all GPUs, and on systems with many cores and GPUs, this leads to many experiments running at once, all trying to lock the GPU for use, leaving the cores heavily under-utilized. So by default, DAI always uses CPU for LightGBM, unless ‘on’ is specified.
num_gpus_per_hyperopt_dask¶
#GPUs/HyperOptDask (-1 = all) (Number) (Expert Setting)
Default value -1
Number of GPUs to use per model hyperopt training task. Set to -1 for all GPUs. For example, when this is set to -1 and there are 4 GPUs available, all of them can be used for the training of a single model across a Dask cluster. Ignored if GPUs disabled or no GPUs on system. In multinode context, this refers to the per-node value.
