text-me-keras 0.1.1

A TenosorFlow callback that texts you back (to let you know how training is going).

Text Me Keras

A TensorFlow callback that texts back... to let you know how training is going.

Have you ever found yourself at a party, all your friends are getting hundreds of texts... but not you? Well, now you can be popular. Just add this callback when training your models and it will send you a summary of your training procedure! Say goodbye to those lonely, message-free lock screens with the TextMeKeras callbacks!

Usage.

---

Clone and Install.

git clone https://github.com/djvaroli/text_me_keras.git && cd text_me_keras/ && pip install -e .

Or

pip install git+https://github.com/djvaroli/text_me_keras.git

Export Twilio Credentials

Note: If you don't have Twilio credentials, you can create a free account at https://www.twilio.com/. Then create a new project and get a free phone number as well as the necessary credentials.

Python

import os

os.environ["TWILIO_ACCOUNT_SID"] = <your_account_sid>
os.environ["TWILIO_AUTH_TOKEN"] = <your_auth_token>
