I was trying your tutorial from here:https://thekevinscott.com/image-classification-with-javascript/
Everything works fine until I call model.fit(). Below is the exception I get.
Error: Error when checking input: expected flatten_Flatten1_input to have shape [,7,7,256], but got array with shape [2,224,224,3]
If I change this line: tf.layers.flatten({inputShape: [7, 7, 256]}) to tf.layers.flatten({inputShape: [224, 224, 3]}), the browser crashes. Can you tell me what I'm doing wrong ?
Right now, addData
only accepts an array of tf.Tensor3D
(for instance, the output of tf.fromPixels
).
This method should be updated to accept:
tf.Tensor3D[]
Uint32Array[]
ImageData[]
Trying to reproduce the README example:
const loadImage = (src) => new Promise((resolve, reject) => {
const image = new Image();
image.src = src;
image.crossOrigin = 'Anonymous';
image.onload = () => resolve(image);
image.onerror = (err) => reject(err);
});
const pretrainedModelURL = 'https://storage.googleapis.com/tfjs-models/tfjs/mobilenet_v1_0.25_224/model.json';
tf.loadModel(pretrainedModelURL).then(model => {
const layer = model.getLayer('conv_pw_13_relu');
return tf.model({
inputs: [model.inputs[0]],
outputs: layer.output,
});
}).then(pretrainedModel => {
return tf.loadModel('/model.json').then(model => {
return loadImage('/trees/tree1.png').then(loadedImage => {
const image = tf.reshape(tf.fromPixels(loadedImage), [1,224,224,3]);
const pretrainedModelPrediction = pretrainedModel.predict(image);
const modelPrediction = model.predict(pretrainedModelPrediction);
const prediction = modelPrediction.as1D().argMax().dataSync()[0];
console.log(prediction);
});
});
}).catch(err => {
console.error('Error', err);
});
I have an error from the line:
const pretrainedModelPrediction = pretrainedModel.predict(image);
The error is the next one:
tfjs.js:67 Uncaught (in promise) Error: The dtype of the feed (int32) is incompatible with that of the key 'input_1' (float32).

Any idea about this error? My tfjs version is 0.12.2
.
I think the things you do are great and useful. For convenience, I want to use the model downloaded directly from your web demo. How do I add it to my script in html?
I just do this , it don't work.
function loadMobilenet() {
return tf.loadModel('./model.json');
}
Thank you!
Getting a Cannot read property 'sourceLayer' of undefined
while trying to load pre-trained model (both 'mobilenet_v1_0.25_224' and 'mobilenet_v1_1.0_224'.
Tried with both tf-js v0.12.2 and latest v0.15.3
Tensorflow.js is at 0.15.3 with a number of functions renamed in anticipation of a 1.0 release. This library should be updated to use the latest tfjs.
