this is the error I get when running the project any clues?

@Hubert1403 sounds like you are hitting this Windows issue: https://github.com/Lauszus/FaceRecognitionApp/issues/19#issuecomment-400646148. Can you try to put the project somewhere with a shorter path?

I'm closing this due to a lack of response. Feel free to reopen if you still are having issues.
