ImportError: cannot import name 'DeferredConfigManager' from 'pymlconf'

[mehrdad-dev]

Hi
first of all i install libgl1-mesa-dev , portaudio19-dev and cython
and then install tuner with pip
but when I run it with the tuner command in terminal, I got this error:
ImportError: cannot import name 'DeferredConfigManager' from 'pymlconf'

I installed the pymlconf lib after it, but still, I got this error.
Can you help me?

Oh, sorry.

I updated the pymlconf package and forget to update this.

Thanks for the issue, I'll fix it asap.

@mehrdad-dev,

I have already done these steps and unfortunately cannot reproduce the issue:

sudo apt install libgl1-mesa-dev portaudio19-dev libsdl1.2-dev
pip install 'cython <= 0.28.2'
pip install -e .

The tuner was started correctly, but the GUI needs some work.

Please try the latest commit on the master branch and inform me if something went wrong.

[mehrdad-dev]

yes, thank you.
but I think it has some trouble with freq_from_autocorr function.
In fact, I want to create a tuner like this, so can you help me? and guide me in this way.

[pylover]

Interesting.

This project needs some modification across algorithm and GUI. As with the other tuners, the fft function used to detect frequency from the raw audio wave.

Please feel free to send pull requests and asking questions.
