TypeError: Cannot read property 'NativeModule' of undefined, js engine: hermes

[Leli1024]

Im using the latest versions of react native and the tfjs package. But when ai try to import bundleIOResources specifically. I get the error TypeError: Cannot read property 'NativeModule' of undefined, js engine: hermes

My project does not use expo, it is not an expo managed app

Taking a look at the code (I worked on it before), it seems to require some other libraries like expo-asset to work: https://github.com/tensorflow/tfjs/blob/master/tfjs-react-native/src/bundle_resource_io.ts

If you are not using expo, you might not have those libraries then it won't work. I think if you install expo-asset manually it should work.

You can also take what you need from tfjs-react-native/src/platform_react_native.ts into your own repo and then add whatever storage you need manually:

• async storage https://github.com/tensorflow/tfjs/blob/master/tfjs-react-native/src/async_storage_io.ts
• bundle resource https://github.com/tensorflow/tfjs/blob/master/tfjs-react-native/src/bundle_resource_io.ts
• mmkv https://github.com/ai-simulator/tfjs-react-native-mmkv-storage (written by me)

Hi, @Leli1024

I apologize for the delay in my response. Have you had a chance to try the workaround mentioned by @paradite in the previous comment? If so, please let me know if the issue has been resolved or if you are still encountering problems.

Thank you for your cooperation and patience.

Thanks both, I tried the workaround on my bare project and it did not work, but when I coded a dummy app using expo, it did so I'm assuming it is not working because these dependencies just don't work with react native bare projects.

Another thing to note is that when trying to run predictions on images, the app crashes

Same issue here.

Hi everyone, I haven't used this library recently, but this error is usually a sign that your native modules are not loaded.

This could happen if you use expo go, and it's missing a required native module. Expo team decides which modules are included in expo go, so it could be that they removed a module required by tfjs in expo go.

In any case, you should use expo dev client for development and testing, in which you can control which native modules are installed.

Hope this helps.

Same issue here.

This issue is not related to tensorflow it seems, but to expo - I think. But I also couldn't detect where it specifically comes from in my case.

Related to:
expo/expo#29568
expo/expo#31018

The same error occurs when using Expo assets.
