node-red-contrib-model-asset-exchange's Introduction

Node-RED nodes for deep learning microservices from the Model Asset eXchange, providing support for common audio, image, video, and text processing tasks.

Getting started

To get started follow the comprehensive tutorial or complete the quick start steps listed below.

Setup

Docker installation

If you have Docker installed, you can use this Docker image to try out the examples.

Native installation

Install Node-RED.

Before you can install Node-RED, you'll need a working install of Node.js. We recommend the use of Node.js LTS 8.x or 10.x, as Node-RED no longer supports Node.js 6.x or earlier.
Run the following command in your Node-RED user directory - typically ~/.node-red to install the node-red-contrib-model-asset-exchange module:
```
 $ cd ~/.node-red
 $ npm install node-red-contrib-model-asset-exchange
```

You can also install the module in the Node-RED editor. Choose ☰ > Manage palette > Install and enter model-asset as the search term.

Launch Node-RED and open the displayed URL in a web browser to access the flow editor.
```
 $ node-red
   ...
   ... - [info] Server now running at http://127.0.0.1:1880/
```
The nodes are displayed in the palette under the Model-Asset-eXchange category.

Explore the sample flows

The node-red-contrib-model-asset-exchange module includes a couple of example flows to get you started. To import the flows into the workspace:

In the Node-RED editor open ☰ > Import > Examples > model asset exchange.
Select one of the sub-directories to choose between the basic flows in getting started, some more complex examples in beyond the basics, or some flows designed to run on the raspberry pi.
Choose a flow.

Note: The flows utilize nodes from the node-red-contrib-browser-util and node-red-contrib-image-output modules. See the flow description for more details on which nodes are used in a particular example.

You can deploy and run these flows as is. The deep learning nodes in these flows have been pre-configured (service: cloud) to connect to hosted evaluation instances of the deep learning microservices.

Use the nodes in your own flows

Microservice evaluation instances are not suitable for production use. We recommend running microservice instance(s) on your local machine or in the cloud using IBM Cloud Kubernetes, Azure Kubernetes Service, or Google Kubernetes Engine:

Deploy the deep learning microservice in the desired environment.
Take note of its URL (e.g. http://localhost:5000)
Add the corresponding deep learning node to your canvas.
Open the node properties.
Add a service entry for the URL and assign it a unique name.

Supported application domains

This Node-RED node module supports the following application domains:

Image Caption Generator

Generate captions that describe the contents of images.
Object Detector

Localize and identify multiple objects in a single image.
Human Pose Estimator

Detect humans in an image and estimate the pose for each person.
Audio Classifier

Identify sounds in short audio clips.
Inception ResNet v2

Identify objects in images using a third-generation deep residual network.
Image Segmenter

Identify objects in an image, additionally assigning each pixel of the image to a particular object.
Scene Classifier

Classify images according to the place/location labels in the Places365 data set.

Note: file inject node in node-red-contrib-browser-utils is useful to test these nodes.

node-red-contrib-model-asset-exchange's Issues

Update Response Payload for Multiple-Entity Models

Following the format of the facial-emotion-classifier node, update the response payload for models that have the potential for predictions on more than one entity.

this includes:

object-detector
facial-recognizer
facial-age-estimator
image-segmenter
human-pose-estimator

Currently, the first prediction is returned as a string in msg.payload.

This change would convert msg.payload to an object with two properties: entitiesDetected which holds a number value, and prediction which holds an array containing the same number of predictions.

For example, a response with one prediction would look like:

msg.payload = {
  entitiesDetected: 1,
  prediction: ['person']
}

While a response with multiple entities/predictions would look like:

msg.payload = {
  entitiesDetected: 3,
  prediction: ['person', 'dog', 'chair']
}

Demote Mocha to devDependency

Make mocha a devDependency in package.json
Change Travis CI build to install devDependencies

Installation issue on clean Raspbian

Hi,

just tried to install the node straight on clean raspbian without a success.
Are there any prerequisites to get it installed?

Refactor /model/metadata tests

Some /model/metadata endpoint tests are failing because they perform a deep-compare of the returned response. Recently a couple of changes have been delivered to some models, which break those tests.

Add a node (+ sample flow) for the Image Segmenter model

MAX Model URL: https://developer.ibm.com/exchanges/models/all/max-image-segmenter/

Add Mocha tests for all nodes

Travis-CI is executing a Mocha test suite whenever a change is pushed to the repository. Currently there is only a Mocha test defined for the image-caption-generator node, but no tests for other model nodes. We need to add those tests, following the example in https://github.com/CODAIT/node-red-contrib-model-asset-exchange/blob/master/image-caption-generator/test/node_spec.js

Add bounding box/visualization output to nodes

Certain models return coordinates for displaying bounding boxes or other visualization options.

Models that provide this kind of information in their response should have the option to include an augmented image in the output from the model node, like is currently done with the object-detector node.

The nodes that still need this output are:

Remove facial recognizer node

We are withdrawing support for facial recognition models due to privacy concerns.

Refresh sample flows that utilize node-red-contrib-image-output

It appears that changes were made to https://flows.nodered.org/node/node-red-contrib-image-output which cause flows to break that use the image node: Error: Invalid property expression: zero-length.

To fix the issue the property Property needs to be set to msg.payload in the following flows:

object detector
using multiple models

Once the flows were updated https://github.com/CODAIT/max-node-red-docker-image needs to be refreshed.

Add sample Node-RED flow(s)

To illustrate how the nodes can be used:

add standard flow to /examples
publish flow on https://flows.nodered.org/
update /examples/README.md
re-publish module on npm

Remaining nodes without a sample:

inception resnet v2
human pose estimator
facial age estimator

Utilize new long running microservice instances

Update service definition URLs (e.g. https://github.com/CODAIT/node-red-contrib-model-asset-exchange/blob/master/audio-classifier/node.html#L165) to default to the new long running service instances.

Hello,

Nodes cannot handle JSON input

During some random testing I've noticed that if JSON is passed in as input the following error message is displayed in the debug window:

TypeError: source.on is not a function

To recreate:

import any sample flow
choose a JSON document as input

Add node for Facial Emotion Classifier microservice

https://github.com/IBM/MAX-Facial-Emotion-Classifier

All Mocha tests are failing for the /model/predict endpoint

There have been no changes to our code yet all tests for the /model/predict endpoints fail due to a timeout. I verified that the login running instances that this endpoint is accessing are operational (by running curl etc).

Add get_metadata method back to nodes

This method will supply metadata information about the model as defined in the openAPI spec.

some nodes are missing

Hi,
different to the description the scene-classifier and image-segmenter nodes are not included.
best regards

Node predicts only background and not the person

Hi :-)

I'm trying to extract (predict) only image #1 as in the the following screenshot, and as in the codepen example:

In NR, I want to get image #1 but I get only the background image #2 as the image output (msg.payload = msg.annotatedInput):

Here's my flow:

Is this a bug?

Thanks!

Fix broken tests

Some tests are failing (https://travis-ci.org/CODAIT/node-red-contrib-model-asset-exchange/jobs/507979780) due to changes to the microservices:
