I Tried to change the version of node js and python still not working.
node js : v18.20.5
Python : 3.11.3

here is the code:

index.js: import express from 'express'
import cors from 'cors'
import ImageClassifier from './ImageClassifier.js';

(async () => {
const classifier = new ImageClassifier();

// Train the model
const datasetPath = path.join(process.cwd(), './dataset');
await classifier.train(datasetPath, 5); // Adjust epochs if needed

// Save the trained model
const modelPath = path.join(process.cwd(), './model');
await classifier.saveModel(modelPath);
                                                        
// Load the saved model and classify an image
await classifier.loadModel(modelPath);
const testImagePath = path.join(process.cwd(), './testimage/testimg.png');
const result = await classifier.classify(testImagePath);

console.log('Prediction:', result);

})();
ImageClassification.js:

import express from 'express'
import cors from 'cors'
import ImageClassifier from './ImageClassifier.js';

(async () => {
const classifier = new ImageClassifier();

// Train the model
const datasetPath = path.join(process.cwd(), './dataset');
await classifier.train(datasetPath, 5); // Adjust epochs if needed

// Save the trained model
const modelPath = path.join(process.cwd(), './model');
await classifier.saveModel(modelPath);
                                                        
// Load the saved model and classify an image
await classifier.loadModel(modelPath);
const testImagePath = path.join(process.cwd(), './testimage/testimg.png');
const result = await classifier.classify(testImagePath);

console.log('Prediction:', result);

})();

Hi @GaUrAv001001 ,

I noticed you are using nodejs v18.20.5. Could you please try using Python version 3.11.x and Node.js v19.9.x or 20.15.x? After making these changes, please delete the node_modules folder from your project and run npm install again.

Please let me know if this resolves the issue. Thank you!"

[Roman233]

I was getting the same error and after doing what you said the error still exists so it didn't work.

[shmishra99]

Hi @Roman233,

It must resolve your issue. However, if you are still facing the issue even after installing the compatible dependencies, you can manually copy the file from node_modules/@tensorflow/tfjs-node/deps/lib/tensorflow.dll to node_modules/@tensorflow/tfjs-node/lib/napi-v8/. This should resolve your issue.

Let me know if it helps. Thank you!!

YES! I have exactly the same error! I haven’t been able to do anything with her for a week now! Installed, reinstalled everything, node versions, visual studio, python, copied files, NOTHING! I currently have node v18.20.5, [email protected]
@tensorflow/[email protected]

[shmishra99]

@Igor5005 , Please try installing the latest @tensorflow/[email protected] and applying the configuration mentioned in my previous comment. If still you encounter an error related to the missing tensorflow.dll file, manually copy the file to the node_modules/@tensorflow/tfjs-node/lib/napi-v8/ directory.

[Igor5005]

I tried to do as you recommended. Currently:G:\TensorFlow>node -v v18.20.5. G:\TensorFlow>python --version Python 3.11.0 G:\TensorFlow>node-gyp --version v11.0.0
G:\TensorFlow>cl Microsoft (R) C/C++ optimizing compiler version 19.42.34436 для x86. G:\TensorFlow>npm list @tensorflow/tfjs
[email protected] G:\TensorFlow -- @tensorflow/[email protected] -- @tensorflow/[email protected] . My Windows: Windows10 PRO, I copied the tensorflow.dll file from the G:\TensorFlow\node_modules@tensorflow\tfjs-node\deps\lib folder to the G:\TensorFlow\node_modules@tensorflow\tfjs-node folder \lib\napi-v8

The file I tried to run:
const tf = require('@tensorflow/tfjs-node');
console.log(tf.version.tfjs);
const tensor = tf.tensor([1, 2, 3, 4]);
console.log('Tensor:', tensor.toString());

Result: [Running] node "g:\TensorFlow\index.js"
g:\TensorFlow\node_modules@tensorflow\tfjs-node\dist\index.js:61
throw new Error("The Node.js native addon module (tfjs_binding.node) can not " +
^

Error: The Node.js native addon module (tfjs_binding.node) can not be found at path: g:\TensorFlow\node_modules@tensorflow\tfjs-node\lib\napi-v8\tfjs_binding.node.
Please run command 'npm rebuild @tensorflow/tfjs-node --build-addon-from-source' to rebuild the native addon module.
If you have problem with building the addon module, please check https://github.com/tensorflow/tfjs/blob/master/tfjs-node/WINDOWS_TROUBLESHOOTING.md or file an issue.

I forgot to indicate the video card, it's quite old, nvidia geforce 8600GT

[shmishra99]

@Igor5005 Run command npm rebuild @tensorflow/tfjs-node --build-from-source. It must work.

[shmishra99]

@GaUrAv001001, Please also verify if this workaround is also working in your case.

[Igor5005]

I did it. same error...

[atellmer]

you can manually copy the file from node_modules/@tensorflow/tfjs-node/deps/lib/tensorflow.dll to node_modules/@tensorflow/tfjs-node/lib/napi-v8/.

worked for me
