A small library to get a notification when your training is complete or when it crashes during the process with two additional lines of code.
When training deep learning models, it is common to use early stopping. Apart from a rough estimate, it is difficult to predict when the training will finish. Thus, it can be interesting to set up automatic notifications for your training. It is also interesting to be notified when your training crashes in the middle of the process for unexpected reasons.
Install with pip or equivalent.
pip install knockknockThis code has only been tested with Python >= 3.6.
The library is designed to be used in a seamless way, with minimal code modification: you only need to add a decorator on top your main function call. The return value (if there is one) is also reported in the notification.
There are currently twelve ways to setup notifications:
| Platform | External Contributors |
|---|---|
| - | |
| Slack | - |
| Telegram | - |
| Microsoft Teams | @noklam |
| Text Message | @abhishekkrthakur |
| Discord | @watkinsm |
| Desktop | @atakanyenel @eyalmazuz |
| Matrix | @jcklie |
| Amazon Chime | @prabhakar267 |
| DingTalk | @wuutiing |
| RocketChat | @radao |
| WeChat Work | @jcyk |
The service relies on Yagmail a GMAIL/SMTP client. You'll need a gmail email address to use it (you can setup one here, it's free). I recommend creating a new one (rather than your usual one) since you'll have to modify the account's security settings to allow the Python library to access it by Turning on less secure apps.
from knockknock import email_sender
@email_sender(recipient_emails=["<[email protected]>", "<[email protected]>"], sender_email="<grandma'[email protected]>")
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {'loss': 0.9} # Optional return valueknockknock email \
--recipient-emails <[email protected]>,<[email protected]> \
--sender-email <grandma'[email protected]> \
sleep 10If sender_email is not specified, then the first email in recipient_emails will be used as the sender's email.
Note that launching this will asks you for the sender's email password. It will be safely stored in the system keyring service through the keyring Python library.
Similarly, you can also use Slack to get notifications. You'll have to get your Slack room webhook URL and optionally your user id (if you want to tag yourself or someone else).
from knockknock import slack_sender
webhook_url = "<webhook_url_to_your_slack_room>"
@slack_sender(webhook_url=webhook_url, channel="<your_favorite_slack_channel>")
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {'loss': 0.9} # Optional return valueYou can also specify an optional argument to tag specific people: user_mentions=[<your_slack_id>, <grandma's_slack_id>].
knockknock slack \
--webhook-url <webhook_url_to_your_slack_room> \
--channel <your_favorite_slack_channel> \
sleep 10You can also specify an optional argument to tag specific people: --user-mentions <your_slack_id>,<grandma's_slack_id>.
You can also use Telegram Messenger to get notifications. You'll first have to create your own notification bot by following the three steps provided by Telegram here and save your API access TOKEN.
Telegram bots are shy and can't send the first message so you'll have to do the first step. By sending the first message, you'll be able to get the chat_id required (identification of your messaging room) by visiting https://api.telegram.org/bot<YourBOTToken>/getUpdates and get the int under the key message['chat']['id'].
from knockknock import telegram_sender
CHAT_ID: int = <your_messaging_room_id>
@telegram_sender(token="<your_api_token>", chat_id=CHAT_ID)
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {'loss': 0.9} # Optional return valueknockknock telegram \
--token <your_api_token> \
--chat-id <your_messaging_room_id> \
sleep 10Thanks to @noklam, you can also use Microsoft Teams to get notifications. You'll have to get your Team Channel webhook URL.
from knockknock import teams_sender
@teams_sender(token="<webhook_url_to_your_teams_channel>")
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10)
return {'loss': 0.9} # Optional return valueknockknock teams \
--webhook-url <webhook_url_to_your_teams_channel> \
sleep 10You can also specify an optional argument to tag specific people: user_mentions=[<your_teams_id>, <grandma's_teams_id>].
Thanks to @abhishekkrthakur, you can use Twilio to send text message notifications. You'll have to setup a Twilio account here, which is paid service with competitive prices: for instance in the US, getting a new number and sending one text message through this service respectively cost $1.00 and $0.0075. You'll need to get (a) a phone number, (b) your account SID and (c) your authentification token. Some detail here.
from knockknock import sms_sender
ACCOUNT_SID: str = "<your_account_sid>"
AUTH_TOKEN: str = "<your_auth_token>"
@sms_sender(account_sid=ACCOUNT_SID, auth_token=AUTH_TOKEN, recipient_number="<recipient's_number>", sender_number="<sender's_number>")
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10)
return {'loss': 0.9} # Optional return valueknockknock sms \
--account-sid <your_account_sid> \
--auth-token <your_account_auth_token> \
--recipient-number <recipient_number> \
--sender-number <sender_number>
sleep 10Thanks to @watkinsm, you can also use Discord to get notifications. You'll just have to get your Discord channel's webhook URL.
from knockknock import discord_sender
webhook_url = "<webhook_url_to_your_discord_channel>"
@discord_sender(webhook_url=webhook_url)
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {'loss': 0.9} # Optional return valueknockknock discord \
--webhook-url <webhook_url_to_your_discord_channel> \
sleep 10You can also get notified from a desktop notification. It is currently only available for MacOS and Linux and Windows 10. For Linux it uses the nofity-send command which uses libnotify, In order to use libnotify, you have to install a notification server. Cinnamon, Deepin, Enlightenment, GNOME, GNOME Flashback and KDE Plasma use their own implementations to display notifications. In other desktop environments, the notification server needs to be launched using your WM's/DE's "autostart" option.
from knockknock import desktop_sender
@desktop_sender(title="Knockknock Desktop Notifier")
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {"loss": 0.9}knockknock desktop \
--title 'Knockknock Desktop Notifier' \
sleep 2Thanks to @jcklie, you can send notifications via Matrix. The homeserver is the
server on which your user that will send messages is registered. Do not forget the schema for the URL (http or https).
You'll have to get the access token for a bot or your own user. The easiest way to obtain it is to look into Riot looking
in the riot settings, Help & About, down the bottom is: Access Token:<click to reveal>. You also need to specify a
room alias to which messages are sent. To obtain the alias in Riot, create a room you want to use, then open the room
settings under Room Addresses and add an alias.
from knockknock import matrix_sender
HOMESERVER = "<url_to_your_home_server>" # e.g. https://matrix.org
TOKEN = "<your_auth_token>" # e.g. WiTyGizlr8ntvBXdFfZLctyY
ROOM = "<room_alias" # e.g. #knockknock:matrix.org
@matrix_sender(homeserver=HOMESERVER, token=TOKEN, room=ROOM)
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {'loss': 0.9} # Optional return valueknockknock matrix \
--homeserver <homeserver> \
--token <token> \
--room <room> \
sleep 10Thanks to @prabhakar267, you can also use Amazon Chime to get notifications. You'll have to get your Chime room webhook URL.
from knockknock import chime_sender
@chime_sender(webhook_url="<webhook_url_to_your_chime_room>")
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10)
return {'loss': 0.9} # Optional return valueknockknock chime \
--webhook-url <webhook_url_to_your_chime_room> \
sleep 10You can also specify an optional argument to tag specific people: user_mentions=[<your_alias>, <grandma's_alias>].
DingTalk is now supported thanks to @wuutiing. Given DingTalk chatroom robot's webhook url and secret/keywords(at least one of them are set when creating a chatroom robot), your notifications will be sent to reach any one in that chatroom.
from knockknock import dingtalk_sender
webhook_url = "<webhook_url_to_your_dingtalk_chatroom_robot>"
@dingtalk_sender(webhook_url=webhook_url, secret="<your_robot_secret_if_set>", keywords=["<list_of_keywords_if_set>"])
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {'loss': 0.9} # Optional return valueknockknock dingtalk \
--webhook-url <webhook_url_to_your_dingtalk_chatroom_robot> \
--secret <your_robot_secret_if_set> \
sleep 10You can also specify an optional argument to at specific people: user_mentions=["<list_of_phonenumbers_who_you_want_to_tag>"].
You can use RocketChat to get notifications. You'll need the following before you can post notifications:
- a RocketChat server e.g. rocketchat.yourcompany.com
- a RocketChat user id (you'll be able to view your user id when you create a personal access token in the next step)
- a RocketChat personal access token (create one as per this guide)
- a RocketChat channel
from knockknock import rocketchat_sender
@rocketchat_sender(
rocketchat_server_url="<url_to_your_rocketchat_server>",
rocketchat_user_id="<your_rocketchat_user_id>",
rocketchat_auth_token="<your_rocketchat_auth_token>",
channel="<channel_name>")
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {'loss': 0.9} # Optional return valueYou can also specify two optional arguments:
- to tag specific users:
user_mentions=[<your_user_name>, <grandma's_user_name>] - to use an alias for the notification:
alias="My Alias"
knockknock rocketchat \
--rocketchat-server-url <url_to_your_rocketchat_server> \
--rocketchat-user-id <your_rocketchat_user_id> \
--rocketchat-auth-token <your_rocketchat_auth_token> \
--channel <channel_name> \
sleep 10WeChat Work is now supported thanks to @jcyk. Given WeChat Work chatroom robot's webhook url, your notifications will be sent to reach anyone in that chatroom.
from knockknock import wechat_sender
webhook_url = "<webhook_url_to_your_wechat_work_chatroom_robot>"
@wechat_sender(webhook_url=webhook_url)
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)
return {'loss': 0.9} # Optional return valueknockknock wechat \
--webhook-url <webhook_url_to_your_wechat_work_chatroom_robot> \
sleep 10You can also specify an optional argument to tag specific people: user-mentions=["<list_of_userids_you_want_to_tag>"] and/or user-mentions-mobile=["<list_of_phonenumbers_you_want_to_tag>"].
When using distributed training, a GPU is bound to its process using the local rank variable. Since knockknock works at the process level, if you are using 8 GPUs, you would get 8 notifications at the beginning and 8 notifications at the end... To circumvent that, except for errors, only the master process is allowed to send notifications so that you receive only one notification at the beginning and one notification at the end.
Note: In PyTorch, the launch of torch.distributed.launch sets up a RANK environment variable for each process (see here). This is used to detect the master process, and for now, the only simple way I came up with. Unfortunately, this is not intended to be general for all platforms but I would happily discuss smarter/better ways to handle distributed training in an issue/PR.
