TensorSpace is a neural network 3D visualization framework built using TensorFlow.js, Three.js and Tween.js. TensorSpace provides Keras-like APIs to build deep learning layers, load pre-trained models, and generate a 3D visualization in the browser. From TensorSpace, it is intuitive to learn what the model structure is, how the model is trained and how the model predicts the results based on the intermediate information. After preprocessing the model, TensorSpace supports to visualize pre-trained model from TensorFlow, Keras and TensorFlow.js.

Motivation
TensorSpace is a neural network 3D visualization framework designed for not only showing the basic model structure, but also presenting the processes of internal feature abstractions, intermediate data manipulations and final inference generations.
By applying TensorSpace API, it is more intuitive to visualize and understand any pre-trained models built by TensorFlow, Keras, TensorFlow.js, etc. TensorSpace introduces a way for front end developers to be involved in the deep learning ecosystem. As an open source library, TensorSpace team welcomes any further development on visualization applications.
* Interactive -- Use Layer API to build interactive model in browsers.
* Intuitive -- Visualize the information from intermediate inferences.
* Integrative -- Support pre-trained models from TensorFlow, Keras, TensorFlow.js.

#### Install in the Basic Case
- Step 1: Download Dependencies
Download dependencies build files TensorFlow.js (tf.min.js), Three.js (three.min.js), Tween.js (tween.min.js), TrackballControls (TrackballControls.js).
- Step 2: Download TensorSpace
Download TensorSpace build file tensorspace.min.js from Github, NPM, TensorSpace official website or CDN:
``html`
- Step 3: Include Build Files
Include all build files in web page.
`html`
#### Install in the Progressive Framework
- Step 1: Install TensorSpace
- Option 1: NPM
`bash`
npm install tensorspace
- Option 2: Yarn
`bash`
yarn add tensorspace
- Step 2: Use TensorSpace
`javascript`
import * as TSP from 'tensorspace';
Checkout this Angular example for more information.

Before applying TensorSpace to visualize the pre-trained model, there is an important pipeline - TensorSpace model preprocessing ( Checkout this article for more information about TensorSpace preprocessing ). We can use TensorSpace Converter to quickly complete the TensorSpace Preprocessing.
For example, if we have a tf.keras model in hand, we can use the following TensorSpace-Converter conversion script to convert a tf.keras model to the TensorSpace compatible format:
`shell`
$ tensorspacejs_converter \
--input_model_from="tensorflow" \
--input_model_format="tf_keras" \
--output_layer_names="padding_1,conv_1,maxpool_1,conv_2,maxpool_2,dense_1,dense_2,softmax" \
./PATH/TO/MODEL/tf_keras_model.h5 \
./PATH/TO/SAVE/DIR
Note:
* Make sure to install tensorspacejs pip package, and setup a TensorSpace-Converter runtime environment before using TensorSpace-Converter to preprocess the pre-trained model.
* Based on different training libraries, we provide different preprocessing tutorials: TensorFlow Tutorial, Keras Tutorial, TensorFlow.js Tutorial.
* Checkout TensorSpace-Converter Repo for more information about TensorSpace-Converter.

If TensorSpace is installed successfully and the pre-trained deep learning model is preprocessed, let's create an interactive 3D TensorSpace model.
For convenience, we will use the the resources from this repository's HelloWorld directory, which includes preprocessed TensorSpace compatible LeNet model and sample input data ("5") as an example to illustrate this step. All source code can be found in helloworld.html.
First, we need to new a TensorSpace model instance:
`JavaScript`
let container = document.getElementById( "container" );
let model = new TSP.models.Sequential( container );
Next, based on the LeNet structure: Input + Padding2D + 2 X (Conv2D & Maxpooling) + 3 X (Dense), build the Topology of the TensorSpace model:
`JavaScript`
model.add( new TSP.layers.GreyscaleInput() );
model.add( new TSP.layers.Padding2d() );
model.add( new TSP.layers.Conv2d() );
model.add( new TSP.layers.Pooling2d() );
model.add( new TSP.layers.Conv2d() );
model.add( new TSP.layers.Pooling2d() );
model.add( new TSP.layers.Dense() );
model.add( new TSP.layers.Dense() );
model.add( new TSP.layers.Output1d({
outputs: ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
}) );
Last, we should load our preprocessed TensorSpace compatible model and use init() method to create the TensorSpace model:`JavaScript`
model.load({
type: "tensorflow",
url: './PATH/TO/MODEL/model.json'
});
model.init(function(){
console.log("Hello World from TensorSpace!");
});
We can get the following Fig. 3 model in the browser if everything looks good.
Fig. 4 - LeNet model without any input data
We provide a extracted file which is a handwritten "5" as the input of our model: (online demo)
`
model.init(function() {
model.predict( image_5 );
});
`
We put the predict( image_5 ) method in the callback function of init() to ensure the prediction is after the initialization complete.

As some models above are extremely large, view them locally may be a good choice.
- Step 1: clone TensorSpace Repo
`bash``
git clone https://github.com/tensorspace-team/tensorspace.git
- Step 2:
Open "html" file in examples folder in local web server.
