Errors starting defy

[4ads4]

Hi,

Windows 10 x64
MiniConda 3
VC++

Installed defy with:
pip install defy

defy all 0x60226a096fdcc916xxxx1feb94f21096fdd9f2a1

Traceback (most recent call last):
File "c:\users\user1\miniconda3\envs\defy\lib\runpy.py", line 197, in _run_module_as_main
return _run_code(code, main_globals, None,

raise KeyError(key)
KeyError: 'network_provider'

It seems I have to set some values in config file ./config.ini. But this file is absent. And there is neither example config no config description in docs.

What should I do to fix the above errors?
