open wav file for analyse

[PeterBan11]

Hello, everyone!

I want to open wav file for analyse with this code:

wavFile = wave.open(self.wavFileName, 'r') self.stream = self.pa.open(format=self.pa.get_format_from_width(wavFile.getsampwidth()), channels=wavFile.getnchannels(), rate=wavFile.getframerate(), input=True, frames_per_buffer=self.chunk_size, stream_callback=self.read_callback)

But i get this problem:

RuntimeWarning: invalid value encountered in cast r = pfi.execute(a, is_real, is_forward, fct)

Hi! I'd like to help you. To better understand and replicate your situation, could you please provide the following information?

1. Which version of Python are you using?
2. Your code references 'self', indicating it's part of a class. Could you provide more context or the object's class definition.
3. It would be helpful to know which libraries you have installed. Running pip freeze in a terminal will list your installed libraries.

Best regards,
