Describe the current behavior

When converting a TensorFlow SavedModel to a tfjs model using tensorflowjs_converter and running it on [email protected], I encountered the following errors:

Uncaught (in promise) Error: Incompatible shape during merge: 1,76,282,64 vs. 1,260,1084,64
In versions 4.4.0 to 4.11.0, I received the following error:
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'backend')
The original model is a fully convolutional model with no fixed input dimensions, designed for image super-resolution. It runs well on TensorFlow. You can find the specific code at https://github.com/OysterQAQ/ACG2vec-model/blob/master/real-cugan_tf/upcunet_v3_tfjs.py.

const test = async () => {

  await tf.setBackend('cpu');
  const model = await tf.loadGraphModel("./models/tfjs_model/model.json");

console.log(111);

  const inputTensor = tf.zeros([1,224, 3080, 3], 'int32');
  const outputTensor = await model.executeAsync(inputTensor);
  if (outputTensor) {
  console.log(outputTensor.dataSync());
} else {
  console.error('outputTensor is undefined');
}
  inputTensor.dispose();
  outputTensor.dispose();
 
}
test();

Describe the expected behavior
