I am trying i basic Tensorflow JS model for text classification But I am getting this shape error
(node:11400) UnhandledPromiseRejectionWarning: Error: Length of values '33693' does not match the size inferred by the shape '10000'.
Here is my code
var X_Train = // tokenize sentences
var Y_Train = // encoded label
const xs = tf.tensor2d(X_Train);
const ys = Y_Train;
console.log('Shape of X ');
console.log(X_Train[0]);
console.log(xs);
console.log('Shape of Y ');
console.log(Y_Train[0]);
console.log(ys);
const model = tf.sequential();
model.add(tf.layers.embedding({
inputDim: 4,
outputDim: 10,
inputLength: 10,
trainable: true
}));
model.add(tf.layers.flatten());
model.add(tf.layers.dense({units: 1, activation: 'sigmoid'}));
model.compile({loss: 'meanSquaredError',optimizer: 'adam'});
model.fit(xs,tf.stack(ys))
Here is my Output

I tried to use different model architecture but still ended up with same error. when I change the loss function I still got some different error. Any idea what am I missing or what model architecture I need to use for that kind of data
xs
andtf.stack(ys)
does not match what the model is expecting – edkeveked
