dacapo-ml 0.3.2

Framework for deployment of volumetric machine learning models, and easy composition of training jobs.

DaCapo

A framework for easy application of established machine learning techniques on large, multi-dimensional images.

dacapo allows you to configure machine learning jobs as combinations of DataSplits, Architectures, Tasks, Trainers, on arbitrarily large volumes of multi-dimensional images. dacapo is not tied to a particular learning framework, but currently only supports torch with plans to support tensorflow.

Installation and Setup

Currently, python>=3.10 is supported. We recommend creating a new conda environment for dacapo with python 3.10.

conda create -n dacapo python=3.10
conda activate dacapo

Then install DaCapo using pip with the following command:

pip install dacapo-ml

This will install the minimum required dependencies.

You may additionally utilize a MongoDB server for storing outputs. To install and run MongoDB locally, refer to the MongoDB documentation here.

The use of MongoDB, as well as specifying the compute context (on cluster or not) should be specified in the dacapo.yaml in the main directory.

Functionality Overview

Tasks we support and approaches for those tasks:

• Instance Segmentation
  • Affinities
  • Local Shape Descriptors
• Semantic segmentation
  • Signed distances
  • One-hot encoding of different types of objects

Example Tutorial
