I am also getting this same error no matter if I create a new project and add react-native-pytorch-core or try to add it to an existing project. I am using react native version 0.71.6 and pytorch core version 0.2.4.

Same here, I am also getting this issue with a clean app with only react-native-pytorch-core installed. Any updates?

Not yet, its very frustrating to get any pytorch model into android app using react-native. Hoping this problem to be fixed with future releases.

[SpyGuy0215]

Is there any fix for now? I kinda need this

[TommiHonkanen]

I think react-native-pytorch-core doesn't support react native 0.71 yet. I created an app with react native version 0.70 and didn't get this error,

For demo purpose you can run the project using expo and playtorch app on ios or android device.

[QuinceyJames]

It looks like react native intentionally remove the contents of the android folder to reduce their package size. Please see react-native-community/discussions-and-proposals#508

[yMayanand]

which version of pytorch-core you were working with?

[PierreLepagnol]

Hi, I got the same error for expo sdk version 48, but not for sdk 47.
Here is my package.json :

{
  "name": "test",
  "version": "1.0.0",
  "scripts": {
    "start": "expo start --dev-client",
    "android": "expo run:android",
    "ios": "expo run:ios",
    "web": "expo start --web"
  },
  "dependencies": {
    "expo": "~47.0.14",
    "expo-status-bar": "~1.4.2",
    "react": "18.1.0",
    "react-native": "0.70.8",
    "react-native-pytorch-core": "^0.2.4",
    "expo-splash-screen": "~0.17.5"
  },
  "devDependencies": {
    "@babel/core": "^7.12.9"
  },
  "private": true
}

Try with this and tell me !

[yMayanand]

when did you run the project laslty with the above configuration, because i am getting the same error everytime not matter which configuration i am running with.

[PierreLepagnol]

I immediately posted this message after launching 😊

Perhaps, test it whith a fresh blank app ?

yeah you were right its working with the configuration that you have suggested. Although it was a blank app but if you have any functional app than it throws Execution failed for task ':app:mergeDebugNativeLibs'. error. But there is a workaround suggested on playtorch website all we have to do is add following code in build.gradle file in android folder of app.

    // ...

    /**
     * Without the packaging options, it will result in the following build error:
     *

I am a tad confused, so do I need to use a lower version of expo, react and react-native , AND also manually change the build.gradle files?

[yMayanand]

yes need to use lower version and manually add the changes in gradle file because i found only this thing to be working.

[CarolinaRMarques]

Due to work-related issues, I, for example, cannot downgrade RN, when will the release for newer RN versions happen? Is this being planned?
