what's the cpp version pywhispercpp bind to?

Forgive me if the question is dumb. I'm totally unfamiliar with pybind. But when I compare pywhispercpp and whispercpp cli, I found the difference.

The comparison is under same conditions:

1. same prompt: "好，我们开始上课。请输出简体中文，以下是专有名词“ （means: ok, let's start the lesson. Please output zh-cn, not zh-tw"
2. this is how cpp is invoked: ./main -l zh -t 8 -m models/ggml-large-v2.bin -osrt --prompt '好,我们开始上课.请输出简体中文' -of /tmp/whisper.cpp.srt /tmp/output005.wav
3. this is how I construct pywhispercpp model:

   model = Model(model, 
                 n_threads=8,
                 n_max_text_ctx=448,
                 max_len=30,
                 split_on_word=True,
                 initial_prompt=prompt,
                 language="zh"
                 )
   segments = model.transcribe(input_audio, new_segment_callback=new_segment_callback)

however, pywhispercpp yields traditional Chinese characters, and its output is not as accurate as whispercpp.

So, is there any difference between pywhispercpp and whispercpp? The version of whispercpp I used is 1.7.1, released four days ago, so I wonder pywhispercpp has not bound to latest one yet?

@zillionare, how did you install pywhispercpp, through pip or from source ?

[zillionare]

can't remember exactly and can't find by history command( weired). But I should follow the readme, so it is probably pip install pywhispercpp.

yeah, the pypi version is very old, I am planning to release a new version soon. Please compile it from source for now and let me know if you still have issues. Make sure to remove the old pypi version or create a new virtual env.
