Obspy 1.1.1 Python 3.6 Linux-CentOS
I installed Obspy using Pip

The error message

AttributeError: 'Proj' object has no attribute 'proj_version'

The program worked fine in a Pypi channel installation but not in a conda-forge.

Your problem is probably connected with a wrong version of pyproj library that you have installed. It should be in version 1.9.5.1. I would recommend to install obspy through conda, conda usually install all the dependencies in proper version.
Could you post your pip list?

[nishr]

After installing the pyproj 1.9.5.1, the problem was resolved. Thank you very much.
My pip list.
