[srslte-users] 5g-EmPOWER contoller for srsLTE.

[Piotr Kulesza]

Hi,

I need help with the launch of 5g-EmPOWER controller for srsLTE. I know
that this is not entirely related to this mailing list but maybe someone
here did it and had similar problems to me? Well, I was able to install
empower-runtime and start the startup script. Unfortunately, however, after
entering the site http://127.0.0.1:8888/ I get this error:

019-09-27 12:59:50,434 - tornado.access - ERROR - 500 GET
/auth/login?next=%2F (127.0.0.1) 0.66ms

2019-09-27 12:59:53,140 - tornado.access - INFO - 302 GET / (127.0.0.1)
0.99ms

2019-09-27 12:59:53,144 - tornado.application - ERROR - Uncaught exception

HTTPServerRequest(protocol='http', host='127.0.0.1:8888', method='GET',
uri='/auth/login?next=%2F', version='HTTP/1.1', remote_ip='127.0.0.1')

Traceback (most recent call last):

  File "/usr/local/lib/python3.7/site-packages/tornado/web.py", line 1697,
in _execute

    result = method(*self.path_args, **self.path_kwargs)

    self.render("login.html", error=self.get_argument("error", ""))

    html = self.render_string(template_name, **kwargs)

    t = loader.load(template_name)

  File "/usr/local/lib/python3.7/site-packages/tornado/template.py", line
445, in load

    self.templates[name] = self._create_template(name)

  File "/usr/local/lib/python3.7/site-packages/tornado/template.py", line
476, in _create_template

    with open(path, "rb") as f:

FileNotFoundError: [Errno 2] No such file or directory:
'/home/nuklab02/empower-runtime/empower/managers/apimanager/templates/login.html'

2019-09-27 12:59:53,145 - tornado.access - ERROR - 500 GET
/auth/login?next=%2F (127.0.0.1) 1.07ms


For now, in order to resolve this error, I tried:

   - change tornado version
   - change commit number
   - change Ubuntu version

Unfortunately, nothing helped. From what I see so far, a tornado python is
not able to generate a template for the site or is unable to find it, I
don't know exactly how the tornado works, so it's difficult for me to say
more accurately.

I will be grateful for any help.
