jax-pyjit 0.3.9

JIT python bindings including the client and data access objects

JAX Image Tools Python API

PyPI Project

Introduction

The pyjit package contains code common to JAX Image Tools (JIT), mostly DL and AI tools. It contains a python client which can be authenticated with a JIT server and allows users to submit image analysis and chain together different analysis steps. Any user with Jackson Laborator credentials, usually given to students and collaborators may auth with the server and use these tools. The development server is located at: https://imagetools-dev.jax.org/ for the user interface and https://imagetools-dev.jax.org/api/webjars/swagger-ui/index.html for the backend analysis server.

Quick Start

Install

poetry add jax-pyjit

Usage for Common Tools

Data Access Object Example

from orgjax.pyjit.dao import StorageKey

This provides an easy way to create JSON objects used with the JIT server. Therefore when creating new image analysis tools it is a useful addition.

Usage of JIT Client

jax-pyjit contains a requests-based client which allows an authenticated user to submit runs and chain together image analysis tools. Jackson Laboratory give credentials to students, external users and collaborators. If you already have credentials, you will be able to use these examples if not then please get in touch and your application to use our JIT Server will be reviewed. Alternatively you may install your own JIT Server (this requires expert kubernetes knowledge as it is a fully distributed design using temporal.io).
