I'm not able to resolve this error. Can someone help me?

Sorry for late, It seems your TensorFlow-lite library cannot be found. Check your library first, please follow the instruction from TensorFlow-lite website, and to make sure each function is workable.

I implemented another project on TensorFlow-lite and it is working fine. So, I don't think problem is with TensorFlow-lite. And even in this code problem is only with Interpreter and InterpreterBuilder. I'm not able to resolve this eror.
