pyATS harness question

I followed the instruction to setup basic harness based on below url.

https://pubhub.devnetcloud.com/media/pyats-packages/docs/genie/userguide/harness/user/gettingstarted.html?highlight=grun

 

The job file (harness1.py) is as below

import os
from genie.harness.main import gRun


def main():
test_path = os.path.dirname(os.path.abspath(__file__))
gRun(mapping_datafile=os.path.join(test_path, 'mapping.yaml'))

The mapping.yaml file is as below

 

devices:
uut:
context: cli
label: uut
mapping:
cli: vty

 

The testbed file(testbed_csrv.yaml) is as below

testbed:

name: GenieTest

tacacs:
username: cisco
passwords:
tacacs: cisco
enable: cisco
line: cisco

devices:
R1:
alias: 'uut'
os: 'iosxe'
type: 'CSR1000v'
connections:
defaults:
class: 'unicon.Unicon'
vty:
protocol: ssh
ip: 172.16.100.130
port: 22

 

When I run easypy harness1.py --testbed_file testbed_csrv.yaml, I got below error message

Caught error while executing the test script:
2019-08-19T20:58:32: %GENIE-ERROR: Traceback (most recent call last):
2019-08-19T20:58:32: %GENIE-ERROR: File "src/genie/harness/main.py", line 379, in genie.harness.main.Genie.run

2019-08-19T20:58:32: %GENIE-ERROR: TypeError: Argument should be a pyATS Testbed object but received object of type <class 'NoneType'>

 

I cannot figure out why the argument received as NoneType object.

Also when edit the harness1.py, pycharm displayed errors for the import.

Unresolved reference 'gRun' and Cannot find reference 'main' in '_init_.py'.

Are they potentially the cause for the testbed object issue?

 

Thank you in advance.
