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 knockknock(For conda users, you can use conda install -c victorsanh knockknock.)
This 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.
There are currently three ways to setup notifications: email, Slack and Telegram.
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_email="<your_email@address.com>", sender_email="<grandma's_email@gmail.com>")
def train_your_nicest_model(your_nicest_parameters):
import time
time.sleep(10000)knockknock email \
--recipient-email <your_email@address.com> \
--sender-email <grandma's_email@gmail.com> \
sleep 10If sender_email is not specified, then recipient_email will be also used for sending.
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 weebhook 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)You 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)knockknock telegram \
--token <your_api_token> \
--chat-id <your_messaging_room_id> \
sleep 10
