[Lonami]

Try now.

[Lonami]

Any reason why you have to use telethon-sync by the way?

[proroot]

Newbie in python(
A lot of code is written, already(

[Lonami]

Okay.

[proroot]

Can the whole project do a search on asyncio?

[Lonami]

"Do a search"?

[Lonami]

Does https://github.com/LonamiWebs/Telethon/commit/e1f8807d837da19a03ca526b0bc98d0976655ca9 fix your issue or not?

[Lonami]

That's not for telethon-sync. I'm asking if running:

pip install --no-cache --upgrade git+https://github.com/LonamiWebs/Telethon@sync

Again has solved your problem or not?

[Lonami]

Oh I see. Wow I'm so dense today :woman_facepalming:

[proroot]

Do you have stable branches?

[Lonami]

Can you try again?

[Lonami]

No there's no such thing as stable branches. Everything can at any moment have a bug.

Well I forgot to remove those. Once more please?

yes, thank you, I hope the other did not fall off)

[Lonami]

There was a not that shouldn't have been there. https://github.com/LonamiWebs/Telethon/commit/872dfdd7d6db2d74008e5e41d5b60e4be96e2590 fixed it.

[proroot]

Thank you)

[kinton]

@Lonami Excuse for troubling. I have a similar problem, the sync library is not available. The problem occurs only on the server, on the local machine everything is in order.

[kinton]

from telethon import TelegramClient

client = TelegramClient('session', api_id, api_hash)

async def main(argv):
    print(argv)
    msg = await client.send_file()
    await client.disconnect()
    return 0

def starter(data):
    with client:
        status = client.loop.run_until_complete(main(data))

[kinton]

@Lonami Using the new version of python, it seems, solved the problem, I will observe.
