sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:bigquery

问题

Trying to create a bigquery connector using sqlalchemy

from sqlalchemy import create_engine
engine = create_engine('bigquery://<project_id>/<project_name>',
                   credentials_path=GCP_KEY)
conn = engine.connect()

Error:

sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:bigquery

回答1:

Your error is generally related to the lack of some required module to use SQLAlchemy.

Therefore, after going though the documentation, I found out that you should install the requirements in you environment using:

pip3 install pybigquery

In addition, within your script you should import the following modules:

1. SQLAchemy

   from sqlalchemy import * from sqlalchemy.engine import create_engine from sqlalchemy.schema import *

2. API Client

   from pybigquery.api import ApiClient

Afterwards, you should have all the necessary packages to execute your code.

If you have any more question about using the SQLAlchemy and API client for BigQuery, you can consult the provided documentation above or I would also be glad to help.
