问题
I have a very small python dataflow package, the structure of package looks like this
.
├── __pycache__
├── pubsubtobigq.py
├── requirements.txt
└── venv
the content of requirements.txt is
protobuf==3.11.2
protobuf3-to-dict==0.1.5
I ran my pipline using this code
python -m pubsubtobigq \
--input_topic "projects/project_name/topics/topic_name" \
--job_name "job_name" \
--output "gs://mybucket/wordcount/outputs" \
--runner DataflowRunner \
--project "project_name" \
--region "us-central1" \
--temp_location "gs://mybucket/tmp/" \
--staging_location "gs://mybucket/staging" \
--requirements_file requirements.txt \
--streaming True
The code which is using this library is like
from protobuf_to_dict import protobuf_to_dict
def parse_proto(message):
dictinoary = protobuf_to_dict(message)
But this line fails saying that protobuf_to_dict is an unknown symbol. Even if i try with google built in method MessageToDict from google.protobuf.json_format i get the same error.
How can i fix this? I need to install either of these libarries
EDIT
Error message when i used MessageToDict from google.protobuf.json_format
