ImportError: No module named api_core.exceptions

Question

I wanted to run a google.cloud.storage dependency to my project so I tried to install this dependency with

sudo pip install --upgrade google-api-python-client

Running the above command, we installed all the required packages in the apache airflow dist-packages directory ex:- dist-packages

When i imported libraries into my project using the below code.

from airflow.contrib.operators.mysql_to_gcs import MySqlToGoogleCloudStorageOperator

running the project on pyhton, i am getting the error ImportError: No module named api_core.exceptions

here is the trace

#python mysql_to_gcs.py

Instead of --upgrade google-api-python-client Just reinstall api-core using
pip install dialogflow

Upgrade has some weird problems which does not update api-core.
