title: Airflow integration with BgQuery Error
body: <p>I have installed airflow and I've written a DAG to integrate MySQL data with BigQuery. </p>
  
  <p>When I run the python script, I got the following error: </p>
  
  <blockquote>
    <p>ImportError: cannot import name GbqConnector</p>
  </blockquote>
  
  <p>I followed the instruction to downgrade pandas to an older version. When I did so I then got a different error:</p>
  
  <blockquote>
    <p>ImportError: cannot import name _test_google_api_imports</p>
  </blockquote>
  
  <p>Edit: the advise from 
  x97Core worked. </p>
  
  <p>I have a different problem now. I am getting the following error:</p>
  
  <blockquote>

  <p>According to this link, the issue is with airflow's compatibility with python2 and pythn3. I've tried running the code on both but the same error still comes up.

  <p>Does anyone know if there is a solution for this?</p>
