    Mosby

    Mosby

    Model-view-presenter and model-view-intent library for modern Android

    Mosby is a model-view-presenter and model-view-intent library designed specifically for Android apps. Migrating a Mosby 2.x based app to Mosby 3.0 should be straightforward. Just replace all import statements of your app in android studio. Mosby has a plugin for Conductor. The aim of this library is to help you build modern android apps with a clean Model-View-Presenter architecture. Furthermore, Mosby helps you to handle screen orientation changes by introducing ViewState and retaining Presenters. At first glance Mosby looks a lot like a framework. There are some classes like MvpFragment you can extends from, but the point is that you don’t have to if you don’t want to. At it’s core Mosby is a tiny library based on delegation. So you don’t have to use MvpFragment if you don’t want to. You can use delegation and composition to integrate Mosby in your own development stack. Hence you are not caught into a frameworks boundaries and limits.

    SageMaker Training Toolkit

    SageMaker Training Toolkit

    Train machine learning models within Docker containers

    Train machine learning models within a Docker container using Amazon SageMaker. Amazon SageMaker is a fully managed service for data science and machine learning (ML) workflows. You can use Amazon SageMaker to simplify the process of building, training, and deploying ML models. To train a model, you can include your training script and dependencies in a Docker container that runs your training code. A container provides an effectively isolated environment, ensuring a consistent runtime and reliable training process. The SageMaker Training Toolkit can be easily added to any Docker container, making it compatible with SageMaker for training models. If you use a prebuilt SageMaker Docker image for training, this library may already be included. Write a training script (eg. train.py). Define a container with a Dockerfile that includes the training script and any dependencies.

    Amazon SageMaker Examples

    Jupyter notebooks that demonstrate how to build models using SageMaker

    Welcome to Amazon SageMaker. This projects highlights example Jupyter notebooks for a variety of machine learning use cases that you can run in SageMaker. If you’re new to SageMaker we recommend starting with more feature-rich SageMaker Studio. It uses the familiar JupyterLab interface and has seamless integration with a variety of deep learning and data science environments and scalable compute resources for training, inference, and other ML operations. Studio offers teams and companies easy on-boarding for their team members, freeing them up from complex systems admin and security processes. Administrators control data access and resource provisioning for their users. Notebook Instances are another option. They have the familiar Jupyter and JuypterLab interfaces that work well for single users, or small teams where users are also administrators. Advanced users also use SageMaker solely with the AWS CLI and Python scripts using boto3 and/or the SageMaker Python SDK.
