import librosa gives LLVM ERROR

pip install librosa==0.5.1I am able to successfully install without errors and also can import llvmlite and numba. However, when I import librosa I get the following error>> import librosa LLVM ERROR: Program used external function '__aeabi_unwind_cpp_pr0' which could not be resolved!I am running Python 2.7.12 with GCC 5.4.0 inside docker with ubuntu-14.04 base.

- Upgrade numba and llvmlite to more recent versions (if availably on rasp)
- If nothing works, you can back off resampy to the older 0.1.x series. It's functionally and API-equivalent, but built on cython instead of numba. It's not a long-term fix, but it should unblock you until the numba issue gets resolved upstream.

- if you have llvmlite and numba working, then you can use resampy >= 0.2. This is true independent of python 2 or 3.
- If you don't have llvmlite working, then you need to use resampy 0.1.x -- 0.1.5 ought to work. You might have to install from source.
- If llvmlite is not working, as it appears from the error you posted below, you should take it up with the llvmlite/numba developers. Librosa is pure python, and only interfaces with llvm through numba.
- if it can't find librosa in your python 3 environment, then it's not installed properly. Maybe try uninstalling and reinstalling librosa?
- I strongly recommend using either a virtual environment (venv) or a conda environment to isolate packages. That way, once you get it working, you can always reconstruct exactly the right versions. Also, conda binary distributions for some of the dependencies (llvmlite, numba, etc) might be more reliable for your OS/hardware. BerryConda might be of interest to you.
