cannot import name 'GenerationMixin' from 'transformers.generation' while running executable file creating using pyinstaller

I am trying to create a application which checks for sentence similarity. Exe file got created.
Getting the below error message while executing .exe file after giving required inputs.

code

model = pickle.load(open(r"miniLM.sav", "rb")) 
sentences_embeddings = model.encode(desc_corpus) 
c_matrix = cosine_similarity(sentences_embeddings, sentences_embeddings)

Error

cannot import name 'GenerationMixin' from 'transformers.generation' (C:UsersUserNameAppDataLocalTemp_MEI198962transformersgeneration__init__.pyc)

I have the latest version of transformers – 4.26.1

Downgraded transformers to – 4.25.1
Issue still persists.
I am not sure what is causing this problem. Can someone please help me out on this?
