Hi, there. I upgraded my telethon version to 1.1.1 (telethon-sync == 1.0.4). It was working tommorow perfectly, but today i have this..

Warning (from warnings module):
  File "C:\Program Files\python3.6.5\lib\multiprocessing\pool.py", line 482
    task = job = obj = None

You should not mix threads with asyncio (which is what the telethon PyPi package uses). The telethon and telethon-sync package are not compatible, install only one. If you don't know what you're doing uninstall telethon and install telethon-sync.

Okay, i'm uninstalled telethon main lib

Traceback (most recent call last):
  File "C:\Users\Администратор.WIN-H2O5EF29JET\Desktop\11\main.py", line 1, in <module>
    from telethon import TelegramClient
ImportError: cannot import name 'TelegramClient'

What version do you have installed now? What does this show?

import telethon
print(telethon.__version__)
print(dir(telethon))

[mdenushev]

>>> import telethon
>>> print(dir(telethon))
['__doc__', '__loader__', '__name__', '__package__', '__path__', '__spec__']
>>> print(telethon.__version__)
Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    print(telethon.__version__)
AttributeError: module 'telethon' has no attribute '__version__'
>>> 

i reinstalled telethon-sync and it's working now
