System information

• Have I written custom code (as opposed to using a stock example script provided in TensorFlow.js): yes
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Mac 10.15.7
• 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): 3.20.0
• Browser version: Chromium 87.0.4280.47
• Tensorflow.js Converter Version: 3.20.0

Describe the current behavior I tried the tutorial for offline usage. When I tried it with model data(multi-pose lightning) from tensorflow-hub and tfjs-backend-webgl, errors below comes out:

Describe the expected behavior It should be executed without error.

Can you please check for a similar issue here https://github.com/tensorflow/tfjs/issues/4405 ?

[JeongJun-Lee]

I already checked it, but the last func in the callstack is different from the issue. The func in the #4406 is reshape() ,but in this issue, the func is Object.identity().

[Sri-harsha99]

Facing similar issue, but related to reshape(). Trying to load the model in Angular.

Code: `` import * as tf from '@tensorflow/tfjs';

    const model = await tf.loadLayersModel('../../assets/model3/model.json');
    console.log(model.predict(tf.tensor(new_sequence,[1,30],'int32')));

Hi @JeongJun-Lee , I apologize for the delay in responding. In order to investigate the issue you are experiencing, could you please share the reproducible code? I believe the issue is caused by importing the same package with different versions. Please follow the instructions in the comment and let us know if the issue is resolved. Thank You !!
