fit_on_batchin configuration files was removed and replaced with adaptive usage of the
utilsmodule was moved from repository root in to
telegram utilsmodules was renamed to
version 0.1.0 all models, embeddings and other downloaded data for provided configurations are
by default downloaded to the
.deeppavlov directory in current user’s home directory.
This can be changed on per-model basis by modifying
or related fields one by one in model’s configuration file.
In configuration files, for all components, dataset readers and iterators
"class" fields are combined
deeppavlov.core.commands.infer.build_model_from_config() was renamed to
build_model and can be imported from the
deeppavlov module directly.
The way arguments are passed to metrics functions during training and evaluation was changed and documented.
Import key components to build HelloBot.
from deeppavlov.skills.pattern_matching_skill import PatternMatchingSkill from deeppavlov.agents.default_agent.default_agent import DefaultAgent from deeppavlov.agents.processors.highest_confidence_selector import HighestConfidenceSelector
Create skills as pre-defined responses for a user’s input containing specific keywords or matching regexps. Every skill returns response and confidence.
hello = PatternMatchingSkill(responses=['Hello world!'], patterns=["hi", "hello", "good day"]) bye = PatternMatchingSkill(['Goodbye world!', 'See you around'], patterns=["bye", "chao", "see you"]) fallback = PatternMatchingSkill(["I don't understand, sorry", 'I can say "Hello world!"'])
Agent executes skills and then takes response from the skill with the highest confidence.
HelloBot = DefaultAgent([hello, bye, fallback], skills_selector=HighestConfidenceSelector())
Give the floor to the HelloBot!
print(HelloBot(['Hello!', 'Boo...', 'Bye.']))

pip install deeppavlov
To use our pre-trained models, you should first install their requirements:
python -m deeppavlov install <path_to_config>
Then download the models and data for them:
python -m deeppavlov download <path_to_config>
or you can use additional key
-d to automatically download all required models and data with any command like
Then you can interact with the models or train them with the following command:
python -m deeppavlov <mode> <path_to_config> [-d]
<path_to_config>should be a path to an NLP pipeline json config (e.g.
deeppavlov/configs/ner/slotfill_dstc2.json) or a name without the
.jsonextension of one of the config files provided in this repository (e.g.
interactbot mode you should specify Telegram bot token in
-t parameter or in
TELEGRAM_TOKEN environment variable.
Also you should use
--no-default-skill optional flag if your component implements an interface of DeepPavlov Skill to skip its wrapping with DeepPavlov DefaultStatelessSkill.
If you want to get custom
/help Telegram messages for the running model you should:
metadata.labels.telegram_utilsparameter with name which refers to the added section of deeppavlov/utils/settings/models_info.json
You can also serve DeepPavlov models for:
riseapi mode you should specify api settings (host, port, etc.) in deeppavlov/utils/settings/server_config.json configuration file. If provided, values from model_defaults section override values for the same parameters from common_defaults section. Model names in model_defaults section should be similar to the class names of the models main component.
Here is detailed info on the DeepPavlov REST API
All DeepPavlov settings files are stored in
deeppavlov/utils/settings by default. You can get full path to it with
python -m deeppavlov.settings settings. Also you can move it with with
python -m deeppavlov.settings settings -p <new/configs/dir/path> (all your configuration settings will be preserved) or move it to default location with
python -m deeppavlov.settings settings -d (all your configuration settings will be RESET to default ones).
predict you can specify path to input file with
--input-file parameter, otherwise, data will be taken
Every line of input text will be used as a pipeline input parameter, so one example will consist of as many lines, as many input parameters your pipeline expects.
You can also specify batch size with
We have built several DeepPavlov based Docker images, which include:
Here is our DockerHub repository with images and deployment instructions.
Jupyter notebooks explaining how to use DeepPalov for different tasks can be found in /examples/
