Command Line Interface

The command line interface (CLI) gives you easy-to-remember commands for common tasks. This page describes the behavior of the commands and the parameters you can pass to them.

Cheat Sheet

CommandEffect
rasa initCreates a new project with example training data, actions, and config files.
rasa trainTrains a model using your NLU data and stories, saves trained model in ./models.
rasa interactiveStarts an interactive learning session to create new training data by chatting to your assistant.

rasa exportExports conversations from a tracker store to an event broker.
rasa xLaunches Rasa X in local mode.
rasa -hShows all available commands.

rasa init

This command sets up a complete assistant for you with some example training data:

rasa init

It creates the following files:

.
├── actions
│ ├── __init__.py
│ └── actions.py
├── config.yml
├── credentials.yml
├── data
│ ├── nlu.yml
│ └── stories.yml
├── domain.yml
├── endpoints.yml
├── models
│ └── <timestamp>.tar.gz
└── tests
└── test_stories.yml

It will ask you if you want to train an initial model using this data. If you answer no, the models directory will be empty.

Any of the default CLI commands will expect this project setup, so this is the best way to get started. You can run rasa train, rasa shell and rasa test without any additional configuration.

rasa train

The following command trains a Rasa Open Source model:

rasa train

If you have existing models in your directory (under models/ by default), only the parts of your model that have changed will be re-trained. For example, if you edit your NLU training data and nothing else, only the NLU part will be trained.

If you want to train an NLU or dialogue model individually, you can run rasa train nlu or rasa train core. If you provide training data only for one one of these, rasa train will fall back to one of these commands by default.

rasa train will store the trained model in the directory defined by --out, models/ by default. The name of the model by default is <timestamp>.tar.gz. If you want to name your model differently, you can specify the name using the --fixed-model-name flag.

The following arguments can be used to configure the training process:

usage: rasa train [-h] [-v] [-vv] [--quiet] [--data DATA [DATA ...]]
[-c CONFIG] [-d DOMAIN] [--out OUT] [--dry-run]
[--augmentation AUGMENTATION] [--debug-plots]
[--num-threads NUM_THREADS]
[--fixed-model-name FIXED_MODEL_NAME] [--persist-nlu-data]
[--force] [--finetune [FINETUNE]]
[--epoch-fraction EPOCH_FRACTION]
{core,nlu} ...
positional arguments:
{core,nlu}
core Trains a Rasa Core model using your stories.
nlu Trains a Rasa NLU model using your NLU data.
optional arguments:
-h, --help show this help message and exit
--data DATA [DATA ...]
Paths to the Core and NLU data files. (default:
['data'])
-c CONFIG, --config CONFIG
The policy and NLU pipeline configuration of your bot.
(default: config.yml)
-d DOMAIN, --domain DOMAIN
Domain specification. This can be a single YAML file,
or a directory that contains several files with domain
specifications in it. The content of these files will
be read and merged together. (default: domain.yml)
--out OUT Directory where your models should be stored.
(default: models)
--dry-run If enabled, no actual training will be performed.
Instead, it will be determined whether a model should
be re-trained and this information will be printed as
the output. The return code is a 4-bit bitmask that
can also be used to determine what exactly needs to be
retrained: - 1 means Core needs to be retrained - 2
means NLU needs to be retrained - 4 means responses in
the domain should be updated - 8 means the training
was forced (--force argument is specified) (default:
False)
--augmentation AUGMENTATION
How much data augmentation to use during training.
(default: 50)
--debug-plots If enabled, will create plots showing checkpoints and
their connections between story blocks in a file
called `story_blocks_connections.html`. (default:
False)
--num-threads NUM_THREADS
Maximum amount of threads to use when training.
(default: 1)
--fixed-model-name FIXED_MODEL_NAME

(default: False)
--force Force a model training even if the data has not
changed. (default: False)
--finetune [FINETUNE]

is provided, Rasa Open Source will try to finetune the
latest trained model from the model directory
specified via '--out'. (default: None)
--epoch-fraction EPOCH_FRACTION
Fraction of epochs which are currently specified in
the model configuration which should be used when
finetuning a model. (default: 1.0)
Python Logging Options:
-v, --verbose Be verbose. Sets logging level to INFO. (default:
None)
-vv, --debug Print lots of debugging statements. Sets logging level
to DEBUG. (default: None)
--quiet Be quiet! Sets logging level to WARNING. (default:

Incremental training

New in 2.2

This feature is experimental. We introduce experimental features to get feedback from our community, so we encourage you to try it out! However, the functionality might be changed or removed in the future. If you have feedback (positive or negative) please share it with us on the Rasa Forum.

In order to improve the performance of an assistant, it's helpful to practice CDD and add new training examples based on how your users have talked to your assistant. You can use rasa train --finetune to initialize the pipeline with an already trained model and further finetune it on the new training dataset that includes the additional training examples. This will help reduce the training time of the new model.

By default, the command picks up the latest model in the models/ directory. If you have a specific model which you want to improve, you may specify the path to this by running rasa train --finetune <path to model to finetune>. Finetuning a model usually requires fewer epochs to train machine learning components like DIETClassifier, ResponseSelector and TEDPolicy compared to training from scratch. Either use a model configuration for finetuning which defines fewer epochs than before or use the flag --epoch-fraction. --epoch-fraction will use a fraction of the epochs specified for each machine learning component in the model configuration file. For example, if DIETClassifier is configured to use 100 epochs, specifying --epoch-fraction 0.5 will only use 50 epochs for finetuning.

You can also finetune an NLU-only or dialogue management-only model by using rasa train nlu --finetune and rasa train core --finetune respectively.

To be able to fine tune a model, the following conditions must be met:

  1. The configuration supplied should be exactly the same as the configuration used to train the model which is being finetuned. The only parameter that you can change is epochs for the individual machine learning components and policies.

  2. The set of labels(intents, actions, entities and slots) for which the base model is trained should be exactly the same as the ones present in the training data used for finetuning. This means that you cannot add new intent, action, entity or slot labels to your training data during incremental training. You can still add new training examples for each of the existing labels. If you have added/removed labels in the training data, the pipeline needs to be trained from scratch.

  3. The model to be finetuned is trained with MINIMUM_COMPATIBLE_VERSION of the currently installed rasa version.

rasa interactive

You can use Rasa X in local mode to do interactive learning in a UI, check out the docs for more details.

If you'd rather use the command line, you can start an interactive learning session by running:

rasa interactive

This will first train a model and then start an interactive shell session. You can then correct your assistants predictions as you talk to it. If UnexpecTEDIntentPolicy is included in the pipeline, action_unlikely_intent can be triggered at any conversation turn. Subsequently, the following message will be displayed:

The bot wants to run 'action_unlikely_intent' to indicate that the last user message was unexpected
at this point in the conversation. Check out UnexpecTEDIntentPolicy docs to learn more.

As the message states, this is an indication that you have explored a conversation path which is unexpected according to the current set of training stories and hence adding this path to training stories is recommended. Like other bot actions, you can choose to confirm or deny running this action.

New in 2.8

UnexpecTEDIntentPolicy was added.

If you provide a trained model using the --model argument, training is skipped and that model will be loaded instead.

During interactive learning, Rasa will plot the current conversation and a few similar conversations from the training data to help you keep track of where you are. You can view the visualization at http://localhost:5005/visualization.html as soon as the session has started. This diagram can take some time to generate. To skip the visualization, run rasa interactive --skip-visualization.

The following arguments can be used to configure the interactive learning session:

rasa shell

You can use Rasa X in local mode to talk to your assistant in a UI. Check out the Rasa X docs for more details.

If you'd rather use the command line, you can start a chat session by running:

rasa shell

By default this will load up the latest trained model. You can specify a different model to be loaded by using the --model flag.

If you start the shell with an NLU-only model, rasa shell will output the intents and entities predicted for any message you enter.

If you have trained a combined Rasa model but only want to see what your model extracts as intents and entities from text, you can use the command rasa shell nlu.

To increase the logging level for debugging, run:

rasa shell --debug

rasa data validate

You can check your domain, NLU data, or story data for mistakes and inconsistencies. To validate your data, run this command:

rasa data validate

The validator searches for errors in the data, e.g. two intents that have some identical training examples. The validator also checks if you have any stories where different assistant actions follow from the same dialogue history. Conflicts between stories will prevent a model from learning the correct pattern for a dialogue.

If you pass a max_history value to one or more policies in your config.yml file, provide the smallest of those values in the validator command using the --max-history <max_history> flag.

You can also validate only the story structure by running this command:

rasa data validate stories
note

Running rasa data validate does not test if your rules are consistent with your stories. However, during training, the RulePolicy checks for conflicts between rules and stories. Any such conflict will abort training.

Also, if you use end-to-end stories, then this might not capture all conflicts. Specifically, if two user inputs result in different tokens yet exactly the same featurization, then conflicting actions after these inputs may exist but will not be reported by the tool.

To interrupt validation even for minor issues such as unused intents or responses, use the --fail-on-warnings flag.

check your story names

The rasa data validate stories command assumes that all your story names are unique!

You can use rasa data validate with additional arguments, e.g. to specify the location of your data and domain files:

usage: rasa data validate [-h] [-v] [-vv] [--quiet]
[--max-history MAX_HISTORY] [-c CONFIG]
[--fail-on-warnings] [-d DOMAIN]
[--data DATA [DATA ...]]

{stories}
stories Checks for inconsistencies in the story files.

validation. (default: None)
-c CONFIG, --config CONFIG
The policy and NLU pipeline configuration of your bot.
(default: config.yml)
--fail-on-warnings Fail validation on warnings and errors. If omitted
only errors will result in a non zero exit code.
(default: False)
-d DOMAIN, --domain DOMAIN
Domain specification. This can be a single YAML file,
or a directory that contains several files with domain
specifications in it. The content of these files will
be read and merged together. (default: domain.yml)
--data DATA [DATA ...]
Paths to the files or directories containing Rasa
data. (default: data)
Python Logging Options:
-v, --verbose Be verbose. Sets logging level to INFO. (default:
None)
-vv, --debug Print lots of debugging statements. Sets logging level
to DEBUG. (default: None)
--quiet Be quiet! Sets logging level to WARNING. (default:
None)
New in 2.8

Story validation is no longer an experimental feature as of 2.8. The feature behaviour remains unchanged.
