Running kcrown ether example

[sreyoshi09]

Hello,
I am running WExplore for the first time. I am having issues running the examples.
I am getting the following error when I am running the kcrown ether example.:
Traceback (most recent call last):
File "/home/sreyoshi/westpa_new/envs/westpa-2017.10/westpa-2017.10/lib/cmds/w_init.py", line 75, in

TypeError: set_node_attributes() got multiple values for keyword argument 'name'

I just installed WExplore plugin. I have only edited the env.sh file.
Attached is the env.sh file. I am not sure what I am doing wrong.

env.sh

This file defines where WEST and GROMACS can be found

Modify to taste

export SCRATCH=$SCRATCH
export WEST_ROOT='/home/sreyoshi/westpa_new/envs/westpa-2017.10/westpa-2017.10'
export GROMACS_ROOT='/home/sreyoshi/gromacs-2016.3_gpu/bin/bin'
export WEST_PYTHONPATH='/home/sreyoshi/westpa_new/envs/WESTPA-WExplore'
export WEST_PYTHON='~/westpa_new/envs/WESTPA-WExplore/bin/python'
##Above parts changed by Sreyoshi Sur 4/8/2019

export PATH="$WEST_PYTHONPATH:$PWD:$ANACONDA_ROOT/bin:$WEST_ROOT/bin/:$GROMACS_ROOT/bin/:$PATH"
export LD_LIBRARY_PATH="$ANACONDA_ROOT/lib:$GROMACS_ROOT/bin:$LD_LIBRARY_PATH"

General stuff now

export WM_ZMQ_MASTER_HEARTBEAT=100
export WM_ZMQ_WORKER_HEARTBEAT=100
export WM_ZMQ_TIMEOUT_FACTOR=100
export WEST_ZMQ_DIRECTORY=server_files
export WEST_LOG_DIRECTORY=job_logs

Files for running the system inside of GROMACS.

export GMX=gmx
export TOP=18-crown-6-K+.top
export NDX=18-crown-6-K+.ndx
export REF=bound_state.tpr

Please let me know if anyone has encountered this error before. When I do 'import wexplore' in the python terminal inside the conda environment it does not show any error. So I don't think there was any installation issue.
