when I was installing noisereduce by pip the error occur.
the same problem with pip install librosa "no module name Cpython" though I had added "install CPython".
If somebody could solve I would sincerely appreciate!!!

For librosa, see #834 (comment).

noisereduce installs fine for me. If you still have problems, please post:

• The complete build log – to show it, click the “Build: failed” caption to the left of the error.
• The relevant parts of your build.gradle file
• Which Chaquopy version you're using

I success on installing noisereduce by removing --index-url from other respository.
However I still fail on installing librosa.

    python {
        buildPython "X:\\pythonEnv\\Scripts\\python.exe"
        pip {
            options "--no-cache-dir"
            install "librosa==0.9.2"
            install "resampy==0.3.1"
            install "numpy"
            install "scipy"
            install "tensorflow"
            install "audiomentations"
            install "tqdm"
            install "noisereduce"
        }
    }

and this is the buid error output:

Chaquopy: Exit status 1

the same problem occur while installing "audiomentations"

I think you must be using an old version of Chaquopy which doesn't use the current repository. Check the version of com.chaquo.python in your app's top-level build.gradle file, and update it to be as new as possible.

Even then, the current version of audiomentations still won't install:

• It requires newer versions of numba and numpy than we currently have for Python 3.8. It might be possible to work around this by using an older version of audiomentations, just as you already are for librosa.

• It requires msgpack, for which there's a workaround in #1299.

• It requires numpy-rms and numpy-minmax, which we don't currently support at all. This also might be possible to work around by using an older version of audiomentations; otherwise, you'll have to build them yourself.
