Please make sure that this is a bug. As per our
GitHub Policy,
we only address code/doc bugs, performance issues, feature requests and
build/installation issues on GitHub. tag:bug_template

System information

• Have I written custom code (as opposed to using a stock example script provided in TensorFlow.js): I wrote custom code
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04):Windows 11 专业版
• Mobile device (e.g. iPhone 8, Pixel 2, Samsung Galaxy) if the issue happens on mobile device:
• TensorFlow.js installed from (npm or script link): npm
• TensorFlow.js version (use command below): @tensorflow/tfjs-node@4.22.0, @tensorflow/tfjs-backend-wasm@4.22.0
• Browser version:
• Tensorflow.js Converter Version:@tensorflow/tfjs-converter@4.22

Describe the current behavior
tf.layers.conv2d are used in the model,Set the tf.setBackend('wasm')，Errors are reported during training：Error: Kernel 'Conv2DBackpropFilter' not registered for backend 'wasm'
Describe the expected behavior
No errors
Standalone code to reproduce the issue

import * as tf from '@tensorflow/tfjs-node';
import '@tensorflow/tfjs-backend-wasm';
createModel(){
const model = tf.sequential();
model.add(
tf.layers.conv2d({
inputShape: [130,6,1],
kernelSize: 3,
filters: 6,
strides: 1,
activation: 'relu',
kernelInitializer: 'varianceScaling',
}),
);
model.add(tf.layers.maxPooling2d({ poolSize: [2, 2], strides: [2, 2] }));
model.add(
tf.layers.conv2d({
kernelSize: 1,
filters: 2,
strides: 1,
activation: 'relu',
kernelInitializer: 'varianceScaling',
}),
);
model.add(tf.layers.maxPooling2d({ poolSize: [2, 2], strides: [2, 2] }));
model.add(tf.layers.flatten());
model.add(
tf.layers.dense({
units: 60,
kernelRegularizer: tf.regularizers.l2({ l2: 0.001 }),
kernelInitializer: 'varianceScaling',
activation: 'relu',
}),
);
model.add(
tf.layers.dense({
units:21,
kernelInitializer: 'varianceScaling',
activation: 'softmax',
}),
);
const optimizer = tf.train.adam();
model.compile({
optimizer: optimizer,
loss: 'categoricalCrossentropy',
metrics: ['accuracy'],
});
return model;
}
async modelFit(model,asyncData
): {
this.setFitState(true);
const data = tf.data
.generator(asyncData)
.shuffle(512)
.batch(512);

await model
.fitDataset(data, {
epochs: 10,
callbacks: {
onTrainBegin: async (logs) => {
this.batchTmie = Date.now();
},
onBatchEnd: (batch, logs)=>{
console.log(batch = ${batch},times=${Date.now())
},
onEpochEnd: async (epoch, logs)=>{
console.log(Epoch ${epoch}:loss = ${logs.loss});
},
},
})
.then(async () => {
await this.saveModel();
})
.catch((e) => {
console.error(e
});
}
const model=createModel()
modelFit(model, data);

Provide a reproducible test case that is the bare minimum necessary to generate
the problem. If possible, please share a link to Colab/CodePen/any notebook.

Other info / logs Include any logs or source code that would be helpful to
diagnose the problem. If including tracebacks, please include the full
traceback. Large logs and files should be attached.

Hi @bjqsyq ,

We appreciate your effort in highlighting this issue. Conv2DBackpropFilter isn't yet supported in the WASM backend. We've logged this as a feature request. Consider using CPU, WebGL, or WebGPU backends for now. i will provide updates on WASM backend support.

Thank You!!
