Tensor data is null

Question

I have a .tflite, then I want to print Layer 22, but it can't work, it displays the error, I don't know how to fix.

My code

import tensorflow as tf
interpreter = tf.lite.Interpreter(model_path='/content/drive/MyDrive/non_RR/tflite_qaware_model.tflite')
interpreter.allocate_tensors()
print(interpreter.get_tensor(22))

The output

ValueError                                Traceback (most recent call last)
<ipython-input-63-d40b7ea1229d> in <cell line: 6>()
      4 interpreter.allocate_tensors()
      5 
----> 6 print(interpreter.get_tensor(22))
