NotImplementedError: Cannot convert a symbolic Tensor (bert/encoder/strided_slice:0) to a numpy array.

Hi! I have a problem in google colab (colab.research.google.com), during start Text_Expansion.ipynb (https://colab.research.google.com/github/dilyararimovna/text_expansion/blob/main/Text_Expansion.ipynb)

==================== Error =============================================== NotImplementedError Traceback (most recent call last)

Can anybody help me? Thanks.
