I am using google cloud to create an event on Cloud Storage to Big Query using Apache Beam pythons library. I was executing an ETL in the “DirectRunner” mode and found no issue. But later when I take everything on dataflow to execute found an error.
Below command used to upload the file and I can see my file is present at location same:-
gsutil cp datapip.csv.gz gs://myproject/data/datapip.csv.gz
Sadly whenever I run the below command to execute my pipeline in cloud mode get an error:-
python dfmypy.py -p myproject -b mybucket -d mydataset

It looks like my apache-beam library installation might be incomplete. Running below command show up the same error:-
pip install apache-beam[gcp]
After running the below command I can execute my code successfully:-
sudo pip install apache-beam[gcp]
The apache-beam package doesn’t include all the stuff to read/write from GCP. To get all that, as well as the runner for being able to deploy your pipeline to CloudDataflow (the DataRunner), we’ll need to install it via sudo pip. It seems wired the error message is not clear, therefore I thought to write a small write-up to help someone.
Happy Machine Learning!
