use the previous version, for example @4.1.0

I am running into this issue with a react-native project.

[Rhysjc]

Experiencing the same issue with a new react-native project. Downgrading to 4.1.0 didn't help.

[anglo2333]

How to fix it. Please let me know by someone.

Having done some digging, I think #7181 introduced this. I assume isTypedArray needs to be added to the React Native platform

[Rhysjc]

tfjs-react-native has tfjs-core as a peer dependency on version 3.7.0 (which doesn't include isTypedArray in the Platform type). I'm not too sure how the versioning of the packages here work, but assuming tfjs follows the same versions, downgrading @tensorflow/tfjs to 3.7.0 in your React Native project may resolve this. I don't have time to try it right now but I will do tomorrow. If this resolves it for anyone please comment.

Edit:
Confirmed that installing @tensorflow/tfjs at 3.7.0 resolves this issue. If someone can provide some direction on how I can correctly update the peer dependencies in tfjs-react-native and update the platform file I'm happy to submit a PR

use the previous version, for example @4.1.0

it works for me. I used the tsjs-node

[Rhysjc]

@huhm potentially I just needed to clear my metro cache and 4.1.0 would have worked. Though I think it's probably best to use the version tfjs-react-native has listed as a peer dependency

[Deeparaj-24]

4.1.0

After dowgrade ,getting same error bro

[ToonTalk]

4.1.0 fixed it for me - not using native react

React Native Expo standalone workflow developers: you need to create a new development build. Downgrading to 3.7.0 worked for me after doing that
