😋 Base Deep Learning project

This repository provides a simple and comprehensive example to use the BaseModel interface. This allows to easily create new models to experiment, train, and use the trained model. The primary objective is to facilitate the learning and comprehension of Deep Learning (DL), and provide convenient methods to make your project easier !

Check the CHANGELOG file to have a global overview of the latest modifications ! 😋

* Check the data processing repository for more information on these modules.

All projects also contain a README.md file, that provides general information on the project features / usage, some links (tutorials / projects) related to the topic, and some example_*.jpynb notebooks for practical usage examples.

Installation and usage

  1. Clone this repository : git clone https://github.com/yui-mhcp/base_dl_project.git
  2. Go to the root of this repository : cd base_dl_project
  3. Install requirements* : pip install -r requirements.txt
