Estoy tratando de ejecutar librosa en mi raspberry pi 3. Después de horas de búsqueda en Internet, finalmente pude instalarlo, pero aún arroja un error cuando intento importarlo. Primero, tuve problemas para instalar la dependencia llvmlite. Finalmente lo instalé con el siguiente código: conda install -c numba llvmlite Uso python 3.4 build con miniconda.

Después de instalar llvmlite pude instalar librosa con pip (no es posible con conda)

pi@raspberrypi:~ $ pip install librosa

¿Alguien tiene idea de cuál podría ser el problema? Estoy agradecido por cualquier pista o consejo. ¡¡¡¡¡Gracias!!!!!
