Telethon: ImportError: cannot import name 'TelegramClient'

[madrileanu]

Hello,
I have just tried to setup a client but i'm receiving an import error:
ImportError: cannot import name 'TelegramClient'

I installed telethon module with pip3 and tried to run the script with python 3.
Is there something I'm missing here?

Thank you in advance!

[Lonami]

@madrileanu yes, you're missing to provide more information.

[madrileanu]

What additional information do you need me to provide? Thanks.

[Lonami]

If applicable, full traceback. Exact Python version, and library version.

Run python3 setup.py gen_tl?

[Pantic14]

Now run but i have the next error:

client.start()
  File "---/Telegram/Telethon/CryptoBot/Telethon-master/telethon/telegram_client.py", line 236, in start
    'You must provide either a phone number or a bot token, '
ValueError: You must provide either a phone number or a bot token, not both (or neither)

[Lonami]

Now that's an issue with your code.

[Pantic14]

My code is very simple only have the next lines:

# Use your own values here
api_id = ---
api_hash = '---
phone_number = '---'

client = TelegramClient('pantic', api_id, api_hash)
client.start()

[Lonami]

Now that's a problem with .start() then… @JosXa.

[Lonami]

I see, documentation (and README.rst) are wrong. You must specify phone on .start(), I will change it.

[Pantic14]

How?
client.start(phone_number)

[Lonami]

@Pantic14 yes.

[Pantic14]

Ok, now run ok.
Thanks

[Lonami]

I pushed https://github.com/LonamiWebs/Telethon/commit/77301378f85ba4976c02e7e5704cdde88cd501a0 (now v0.16.1.1) to address this issue.

If you're installing from GitHub you must run python3 setup.py gen_tl as detailed on the fourth step:

1. Run the code generator: python3 setup.py gen_tl

[basnijholt]

I've installed it with pip, shoudn't it happen automatically then?

[Lonami]

With pip, but from GitHub, right?

[basnijholt]

Yes.

[Lonami]

Well, I thought of adding the line that calls the code generator in setup.py. But that may cause trouble/code didn't look too good with it, so I wasn't sure.

[basnijholt]

Ah, I just took a look at setup.py. I've never seen any Python package before where doing pip install ... doesn't do the building.

[Lonami]

Thing is I don't ship the code generator to PyPi so if I tried running setup.py install and it called the generator from a PyPi install it would fail. So it needs additional checks that make it look odd.

[basnijholt]

I understand your logic, but for the user it's confusing.

Another solution might be improving the error message, like raising some Exception and with a message about running your gen_tl code.

I have same issue:

andrei@andrei-dev:~/Documents/Telegram$ python /home/andrei/Documents/Telegram/telethon.py Traceback (most recent call last): File "/home/andrei/Documents/Telegram/telethon.py", line 1, in <module> from telethon import TelegramClient File "/home/andrei/Documents/Telegram/telethon.py", line 1, in <module> from telethon import TelegramClient ImportError: cannot import name TelegramClient

Code I use to start client is:

`from telethon import TelegramClient

These example values won't work. You must get your own api_id and

api_hash from https://my.telegram.org, under API Development.

api_id =
api_hash = ''
phone = '+*'

client = TelegramClient('session_name', api_id, api_hash)
client.connect()

If you already have a previous 'session_name.session' file, skip this.

client.sign_in(phone=phone)
me = client.sign_in(code=77777) # Put whatever code you received here.`

Thank you.

@madrileanu I have no idea. I don't have such issue:

[madrileanu]

If it helps, this is my distro information:

Distributor ID: Ubuntu
Description: Ubuntu 14.04.5 LTS
Release: 14.04
Codename: trusty

[TiagoDanin]

The error occurs because the file has the same name of package (telethon)

[Lonami]

Thanks @TiagoDanin, I've came accross that isue several times, and yet fail to spot it.

how exactly to install pyaes?
pip3 install pyaes does not work .... for me

[CesMak]

Had to disable anaconda environment now it seems to work fine.

Except I do not know what kind of username I have to write in my script:

for message in client.get_message_history('username', limit=25):
client.download_media(message)

username=chat name of telegram desktop app of the chat I would like to download messages from??
with empty spaces???

[CesMak]

I figured it somehow out and it works username = chatname however saved messages seems not to work:

....
for message in client.get_messages('Saved Messages', limit=80):
client.download_media(message)

python3 multi_img.py

@zhxiaohe why did you post this in a completely unrelated issue? Also, Read the F* Docs. I'm pretty sure the error has a link, and if it doesn't, you're using an old version.

@Lonami I'm so so sorry，I'm going to read the F* Docs.
