Python and Protobuf Knime Configuration Linux

Hi All, 

I'm trying to get Python to work in Knime on a RHEL box and confronted with "Library google.protobuf is missing, required minimum version is 2.5.0". I've downloded the latest version from and followed the instructions for configuration and installation but can't get it to work. Does anyone know how to resolve this issue ? 




I did the same thing and was confused when it didn't work.  For Ubuntu, opening Software Center and installing python-protobuf fixed it.

Great. Thank you. Unfortunately can't get it to work on RHEL. 


We have it running on CentOS 6. Try installing protobuf via pip.

Install using following command:

                  pip install protobuf
