tensorflow
TypeError: Cannot read property 'isTypedArray' of undefined, js engine: hermes
Hi, I want to perform tensor calculation in my React Native project so I have added this package. This is my package.json file:

"typescript": "5.0.4"
},
"engines": {
"node": ">=18"
}
}
This is my App.tsx:
import * as tf from '@tensorflow/tfjs';
import '@tensorflow/tfjs-react-native';
import React, { useCallback, useEffect, useState } from 'react';
import { Button, Text, View } from 'react-native';
const App = () => {
const [isTfReady, setIsTfReady] = useState(false);
const loadTFLibrary = useCallback(async () => {
await tf.ready();
console.log('Tensorflow is ready');
setIsTfReady(true);
}, []);
useEffect(() => {
loadTFLibrary();
}, [loadTFLibrary]);
const printTensor = () => {
if (!isTfReady) {
console.log('Tensorflow is not ready');
return;
}
const ten = tf.zeros([2,2]) // This line works properly
const tens = tf.tensor1d([2], 'float32'); // getting the error here "TypeError: Cannot read property 'isTypedArray' of undefined, js engine: hermes"
};
return (
<View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
<Text>App_Barebone</Text>
<Button title="Press me" onPress={printTensor} />
</View>
);
};
export default App;
When I just run const ten = tf.zeros([2,2]) it runs properly and generates a proper tensor.
Now I want to make my custom tensor from the data I provide with an array. At that time, I am getting the above-mentioned error. I have tried with float32, int32, bool, complex64 and string as well but nothing seems to work.

Hi @kuldip-simform ,
I was able to run the code snippet you provided. It successfully creates tensors, and when running on a browser, it prints the tensor values.
here is my package.json file.
"@expo/metro-runtime": "~3.2.3",
"@tensorflow/tfjs": "^4.21.0",
"@tensorflow/tfjs-react-native": "^1.0.0",
"expo": "~51.0.28",
"expo-status-bar": "~1.12.1",
"react": "18.2.0",
"react-dom": "18.2.0",
"react-native": "0.74.5",
"react-native-web": "~0.19.10"
Can you try with these dependencies that I am using. Also, clear your cache using npm cache clean --force after deleting your node_modules folder.
Let me know if it works. Thank you!
@shmishra99 Thank you for your response. I will try with this packages version
Hi guys my package version is:
"@tensorflow/tfjs": "^4.22.0", "@tensorflow/tfjs-react-native": "^1.0.0"
And i am facing same issue.
@Tarun24RN Can you let me know what is your react-native and expo version. it would be better if you share whole package.json.
I am too having this issue and not able to find solution.

@Tarun24RN I had react-native-cli project and then I have added expo modules to run this library as it depends on expo modules. Have you done similar to this ? @shmishra99 Can this be cause of this issue ?

Yes, I have done same process.
@kuldip-simform I found one file inside node-modules>@tensorflow>tjfs-react-native>dist
export class PlatformReactNative {
/**
* Makes an HTTP request.
*
* see @fetch docs above.
*/
async fetch(path, init, options) {
return fetch(path, init, options);
}
/**

* encoding.
*/
encode(text, encoding) {
// See https://www.w3.org/TR/encoding/#utf-16le
if (encoding === 'utf-16') {
encoding = 'utf16le';
}
return new Uint8Array(Buffer.from(text, encoding));
}
/** Decode the provided bytes into a string using the provided encoding. */
decode(bytes, encoding) {
// See https://www.w3.org/TR/encoding/#utf-16le

}
return Buffer.from(bytes).toString(encoding);
}

//@ts-ignore
return global.nativePerformanceNow();
}
return Date.now();
}
setTimeoutCustom() {
throw new Error('react native does not support setTimeoutCustom');
}
isTypedArray(a) {
return a instanceof Float32Array || a instanceof Int32Array ||
a instanceof Uint8Array || a instanceof Uint8ClampedArray;
}
}
May be because of this code tf.env().registerFlag('IS_REACT_NATIVE', () => navigator && navigator.product === 'ReactNative'); if (tf.env().getBool('IS_REACT_NATIVE')) { setupGlobals(); registerWebGLBackend(); tf.setPlatform('react-native', new PlatformReactNative()); } May be it is throwing error as navigator.product is deprecated @shmishra99 ?
@Tarun24RN Maybe. This can be cause for this. I currently do not have project run. Can you try changing that and check if it solves issue? also can you format this code properly in comment? you can add 3 backtick (`) then in new line add 3 backtick again and then add code between then so it is more readable to all in this thread.
code goes here
Thank you.
tf.env().registerFlag('IS_REACT_NATIVE', () => navigator && navigator.product === 'ReactNative');
I have tried by temporarily removing this check navigator.product === 'ReactNative' and then i rebuild the app but the error remain the same.
Getting the same error while trying to use cameraWithTensors from tfjs-react-native. Seems to be a compatability issue between packages:
https://github.com/expo/expo/issues/30060
