After installing all dependencies, when I run airflow initdb, I get ImportError: cannot import name evaluator_pb2 about tfx HOT 8 CLOSED

Full Error:

Google protobuf is used to generate tfx.proto.evaluator_pb2

Try running python setup.py. You should get:

(taxi_pipeline) aaron@ ~/Documents/github/tfx (object_detection) $ python setup.py 
Generating tfx/proto/evaluator_pb2.py...
protoc is not installed nor found in ../src.  Please compile it or install the binary package.

I followed this blog and installed Google protobuf, now python setup.py works.

airflow initdb worked for me without installing Google protobuf though. Maybe check if you have the pip package protobuf==3.7.0 installed?

from tfx.

Upon doing
pip install proytobuf==3.7.0, I get the following message:
tensorflow-model-analysis 0.12.1 has requirement protobuf==3.7.0rc2, but you'll have protobuf 3.7.0 which is incompatible. tensorflow-transform 0.12.0 has requirement protobuf==3.7.0rc2, but you'll have protobuf 3.7.0 which is incompatible.
and then upon running airflow initdb I get the following error:

And when I uninstall protobuf==3.7.0, do pip install protobuf==3.7.0rc2 I get the following message:
ml-metadata 0.13.2 has requirement protobuf<4,>=3.7, but you'll have protobuf 3.7.0rc2 which is incompatible. tfx 0.12.0 has requirement protobuf<4,>=3.7, but you'll have protobuf 3.7.0rc2 which is incompatible.

Then when I try airflow initdb, I get the following message:

+1 to reinstalling. Another option would be to 'pip freeze' and paste the results into here. Maybe we can reverse-engineer the issue from the packages you have installed.

Hi @zendevil, you need to install protobuf compiler protoc (https://github.com/protocolbuffers/protobuf#protocol-compiler-installation) to generate the corresponding protobuf files. I believe the protobuf PyPi package only installs python side libraries, but not the compiler part.

You can quickly test whether protoc is available by running which protoc.

cc + @ruoyu90 for the setup issue: we should document that protoc is necessary for installing source.

from tfx.

+1 to @zhitaoli protobuf compiler is needed as well as the PyPi protobuf package. Maybe we should error out setup if no protoc found, in addition to adding more documentation.

from tfx.

Please find this link which has clear steps to install protobuf compiler.
