IBM Code Model Asset Exchange: News Text Generator

This repository contains code to instantiate and deploy a text generation model. This model recognizes a text file as an input and outputs a string. The model was trained on the One Billion Word Benchmark (http://arxiv.org/abs/1312.3005) data set. The input to the model is a simple text file, and the output is a string containing the words that are predicted to follow. The model has a vocabulary of approximately 800,000 words.

The model files are hosted on IBM Cloud Object Storage. The code in this repository deploys the model as a web service in a Docker container. This repository was developed as part of the IBM Code Model Asset Exchange and the public API is powered by IBM Cloud.

Pre-requisites:

Note: this model can be very memory intensive. If you experience crashes (such as the model API process terminating with a Killed message), ensure your docker container has sufficient resources allocated (for example you may need to increase the default memory limit on Mac or Windows).

  • docker: The Docker command-line interface. Follow the installation instructions for your system.
  • The minimum recommended resources for this model is 8 GB Memory and 4 CPUs.
  • If you are on x86-64/AMD64, your CPU must support AVX at the minimum.

Deployment options

Deploy from Quay

To run the docker image, which automatically starts the model serving API, run:

$ docker run -it -p 5000:5000 quay.io/codait/max-news-text-generator

This will pull a pre-built image from the Quay.io container registry (or use an existing image if already cached locally) and run it. If you'd rather checkout and build the model locally you can follow the run locally steps below.

Deploy on Red Hat OpenShift

You can deploy the model-serving microservice on Red Hat OpenShift by following the instructions for the OpenShift web console or the OpenShift Container Platform CLI in this tutorial, specifying quay.io/codait/max-news-text-generator as the image name.

Note that this model requires at least 8GB of RAM. Therefore this model will not run in a cluster that was provisioned under the OpenShift Online starter plan, which is capped at 2GB.

Deploy on Kubernetes

You can also deploy the model on Kubernetes using the latest docker image on Quay.

On your Kubernetes cluster, run the following commands:

$ kubectl apply -f https://raw.githubusercontent.com/IBM/MAX-News-Text-Generator/master/max-news-text-generator.yaml

The model will be available internally at port 5000, but can also be accessed externally through the NodePort.

A more elaborate tutorial on how to deploy this MAX model to production on IBM Cloud can be found here.

Run Locally

  1. Build the Model
  2. Deploy the Model
  3. Use the Model
  4. Development
  5. Cleanup

1. Build the Model

Clone this repository locally. In a terminal, run the following command:

$ git clone https://github.com/IBM/MAX-News-Text-Generator.git

Change directory into the repository base folder:

$ cd MAX-News-Text-Generator

To build the docker image locally, run:

$ docker build -t max-news-text-generator .

All required model assets will be downloaded during the build process. Note that currently this docker image is CPU only (we will add support for GPU images later).

2. Deploy the Model

To run the docker image, which automatically starts the model serving API, run:

$ docker run -it -p 5000:5000 max-news-text-generator

3. Use the Model

The API server automatically generates an interactive Swagger documentation page. Go to http://localhost:5000 to load it. From there you can explore the API and also create test requests.

Use the model/predict endpoint to load some seed text (you can use one of the test files from the samples folder) and get predicted output from the API.

Swagger Doc Screenshot

You can also test it on the command line, for example:

$ curl -F "text=@samples/sample1.txt" -XPOST http://localhost:5000/model/predict

You should see a JSON response like that below:

{"status": "ok", "pred_txt": "This is a test rather than an alternative view . </S> "}

4. Development

To run the Flask API app in debug mode, edit config.py to set DEBUG = True under the application settings. You will then need to rebuild the docker image (see step 1).

5. Cleanup

To stop the docker container type CTRL + C in your terminal.
