Prepare for PromptASR model training

[ye0njinkim]

Thank you for providing the framework.

I want to reproduce the PromptASR training using libriheavy, but when I run the prepare_prompt_asr.sh file, I get the following error:

Traceback (most recent call last): 
  File "zipformer_prompt_asr/utils.py", line 429, in <module>  
    get_rare_words(subset=subset, top_k=top_k)  
  File "zipformer_prompt_asr/utils.py", line 116, in get_rare_words  
    with open(txt_path, "r") as file:  
FileNotFoundError: [Errno 2] No such file or directory: 'data/tmp/transcript_words_medium.txt'  

What is this txt file, and which part of the code is responsible for generating it?

Can I save the 'data/manifests/texts_medium' file as a .txt, and use it?

The prepare.sh script is already completed.
