WPTAgent not getting initiated

I was using private instance and recently started migration to wptagent. Hosted in server perfectly with location configured as expected.

Installed all the requirements in WPT client as mentioned in ‘wptagent/install.md at master · WPO-Foundation/wptagent · GitHub

Using batch file to start WPTAgent but getting error, details below . Please help.

Batch File content:
cd C:\wpt_agent_sep2018\wptagent
call npm i -g lighthouse
FOR /L %%x IN (1, 1, 24) DO (
python.exe C:\wpt_agent_sep2018\wptagent\wptagent.py -vvvv --server “http://<>:8081/work/” --location PT_Team_WPTDriver

Error Details :
Traceback (most recent call last):
File “C:\wpt_agent_sep2018\wptagent\wptagent.py”, line 705, in
File “C:\wpt_agent_sep2018\wptagent\wptagent.py”, line 692, in main
browsers = find_browsers()
File “C:\wpt_agent_sep2018\wptagent\wptagent.py”, line 465, in find_browsers
build = get_windows_build()
File “C:\wpt_agent_sep2018\wptagent\wptagent.py”, line 395, in get_windows_build
return int(output.strip().split(’ ')[-1])
ValueError: invalid literal for int() with base 10: ‘’


The above issue been resolved after installing Python3.7 with all modules as mentioned in wptagent/install.md at master · WPO-Foundation/wptagent · GitHub

Now getting parser.add_argument(‘–fps’, type=int, choices=xrange(1, 61), default=10,
NameError: name ‘xrange’ is not defined

Whether WPTAgent compatible with Python3.7?

Please suggest.
