A library to help writing ai functions with ease.

Deeptech

A library that helps with writing ai functions fast.

It ships with a full Documentation of its API and Examples.

Getting Started

Please make sure you have pytorch installed properly as a first step.

pip install deeptech

Then follow one of the examples or check out the api documentation.

Design Principles

The api builds on three core parts: Data, Model or Training. Some parts which are considered core functionality that is shared among them is in the core package.

• Data is concerned about loading and preprocessing the data for training, evaluation and deployment.
• Model is concerned with implementing the model. Everything required for the forward pass of the model is here.
• Training contains all required for training a model on data. This includes loss, metrics, optimizers and trainers.
• Core contains functionality that is shared across model, data and training.

Tutorials & Examples

Starting with tutorials and examples is usually easiest.

Simple Fashion MNIST Examples:

• Fasion MNIST: Simple
• Fasion MNIST: Custom Model
• Fasion MNIST: Custom Loss
• TODO Fasion MNIST: Custom Optimizer
• Fasion MNIST: Custom Dataset

Fashion MNIST

Here is the simplest mnist example, it is so short it can be part of the main readme.

from deeptech.data.datasets import FashionMNISTDataset
from deeptech.model.models import ImageClassifierSimple
from deeptech.training.trainers import SupervisedTrainer
from deeptech.training.losses import SparseCrossEntropyFromLogits
from deeptech.training.optimizers import smart_optimizer
from deeptech.core import Config, cli
from torch.optim import SGD


class FashionMNISTConfig(Config):
    def __init__(self, training_name, data_path, training_results_path):
        super().__init__(training_name, data_path, training_results_path)
        # Config of the data
        self.data_dataset = FashionMNISTDataset

        # Config of the model
        self.model_model = ImageClassifierSimple
        self.model_conv_layers = [32, 32, 32]
        self.model_dense_layers = [100]
        self.model_classes = 10

        # Config for training
        self.training_loss = SparseCrossEntropyLossFromLogits
        self.training_optimizer = smart_optimizer(SGD)
        self.training_trainer = SupervisedTrainer
        self.training_epochs = 10
        self.training_batch_size = 32


# Run with parameters parsed from commandline.
# python -m deeptech.examples.mnist_simple --mode=train --input=Datasets --output=Results
if __name__ == "__main__":
    cli.run(FashionMNISTConfig)

Contributing

Currently there are no guidelines on how to contribute, so the best thing you can do is open up an issue and get in contact that way. In the issue we can discuss how you can implement your new feature or how to fix that nasty bug.

To contribute, please fork the repositroy on github, then clone your fork. Make your changes and submit a merge request.

Origin of the Name

The name is a tribute to the deeptech:ai hackathon. When writing the library for fast, accessible ai development, I remembered how helpfull such a library could have been for a hackathon. Thus, I decided to name it as a tribute to that hackathon.

And besides, the name does not seem to be used for any company or library and sounds cool, at least to me. ;)
