I need to import Pubsub_v1 and bigquery from google.cloud module. I have installed it and pip freeze shows below :

gapic-google-cloud-pubsub-v1==0.15.4
google-cloud-bigquery==0.26.0
google-cloud-pubsub==0.27.0
proto-google-cloud-pubsub-v1==0.15.4

In my python script, i am importing the modules as below:

import os 
from google.cloud import pubsub_v1 
import time 
import json 
from google.cloud import bigquery 

The script is throwing error as :

ImportError: cannot import name pubsub_v1

If i run $sudo pip install --upgrade google-cloud-pubsub then It is able to import pubsub but failing to import Bigquery. I need both modules. Can anybody please help ?

Upgraded the other google.cloud modules using

$sudo pip install --upgrade google-cloud-bigquery
$sudo pip install --upgrade google-cloud-storage
$sudo pip install --upgrade google-cloud-logging

It resolves the issue.
