NoSuchModuleError: teradata can't load plugin sqlalchemy

I am trying to connect to teradata server to load the data from pandas DataFrame to teradata using the following create engine

 import teradata
 import teradatasql
 from sqlalchemy import create_engine
 import sqlalchemy_teradata
 import pandas as pd
 engine=create_engine("teradata://user:pwd@host/DataBase")

 Error:
 NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:teradata

I would appreciate your help. Can somebody help?

Solution

  • I would first check to make sure both of these packages were installed correctly and are imported successfully: 

     from sqlalchemy import create_engine
 import sqlalchemy_teradata

    If so, I would restart your Python session - I was getting the same error as you and it finally went away after rebooting.

    If you are still running into issues, try this string: 

    td_engine=create_engine('teradata://'+uid+':'+password+'@'+server+'/'+db+'?driver='+driver)
