Answer 1

If you have previously installed packages, either reboot with a fresh copy of OS or create a virtual environment, as suggested by others. Creating virtual env did not work at the first try for me, you might want to reboot to a fresh copy.

Then install virtualenv and create a new virtualenv.

Activate the virtualenv using python3.

sudo apt-get install llvm

You should get llvm 7.0.x

Then install a compatible llvmlite - this works for 7.0. Get the path by typing which llvm-config In my case it was /usr/bin/llvm-config

LLVM_CONFIG=/usr/bin/llvm-config pip3 install llvmlite==0.32

install dependencies

pip3 install numpy==1.16.1 numba==0.49

pip3 install librosa

If you get an error after trying to import librosa due to numpy, update dependencies

sudo apt-get install libatlas-base-dev
