Hey team, After add the following lines in my 

airflow.cfg

 file. (follow this documentation https://datahubproject.io/docs/metadata-ingestion#using-datahubs-airflow-lineage-backend-recommended)

[lineage]
backend = datahub_provider.lineage.datahub.DatahubLineageBackend
datahub_kwargs = {
    "datahub_conn_id": "datahub_rest_default",
    "capture_ownership_info": true,
    "capture_tags_info": true,
    "graceful_exceptions": true }

Airflow show me this error:

airflow-webserver_1  | [2021-07-30 00:47:44,154] {configuration.py:468} ERROR - No module named 'datahub_provider'
airflow-webserver_1  | [2021-07-30 00:47:59,084] {configuration.py:468} ERROR - No module named 'datahub_provider'
airflow-webserver_1  | [2021-07-30 00:48:13,803] {configuration.py:468} ERROR - No module named 'datahub_provider'

Are there something to do before these steps? Like "pip installl" something? I'm using Airflow 2.1.2.

@proud-church-91494 you are right! Take a look at the guide here (https://registry.astronomer.io/providers/datahub)

That's works, thank you very much!!!👏👏👏👏
