Slack update of training Progress

SlackBot Message

In this blogpost, I will show how you can make your python scripts notify you for the progress of your training, through Slack messages.

SlackBot Message

Slack is a popular tool for team communication that offers some very nice utilities. One of this is the ability to forward emails sent to a specific email address. As shown following gif, all you have to do is enable this functionality in Project Preferences > Message and Media > Get a Forwarding Email Address.



A seemingly random forwarding email address will be assigned to you by Slack. Every email you send to that address will appear as a message in your chat with the slack bot.

You can leverage this utility to send automatic updates from your python code regarding the progress of long-running training scripts. I especially like to use this notification messages for updates related to unexpected events that require action, like code crashes. It’s pretty devastating to start training on Friday only to see 2 days after that something went wrong 2 hours later. Moreover, the use of slack helps me avoid polluting my email inbox.

The following python code can be easily added to a try-catch statement that wraps my code


import smtplib
# Import the email modules we'll need
from email.mime.text import MIMEText

    #trainning code
except Exception as error:
    # Open a plain text file for reading.  For this example, assume that
    # the text file contains only ASCII characters.

    msg = MIMEText("Trainning Message!")
    msg['Subject'] = 'Update for Experiment : Experiment1'
    msg['From'] = ''
    #the slack email
    msg['To'] = ""

    # Send the message via our own SMTP server. Depending on your mailing servers configuration different 
    #methods might need to be invoked. Here i have to use SMTP_SSL
    s = smtplib.SMTP_SSL('')

    s.login("yourUserName", "yourPassword)


The code snipper above works for my configuration, but it can easily be modified for gmail:

server = smtplib.SMTP('', 587)
