There Might be ``` AttributeError: module 'numpy' has no attribute 'long' ``` When importing numba when importing librosa. It's because the numba version was old in our system, which depends on an older version of numpy. # Solution We have to re-install a newer version of numba for librosa 1. Update conda ``` conda update conda ``` 2. uninstall numba ``` pip uninstall -y numba pip3 uninstall -y numba ``` 3. check if uninstalled ``` conda list numba ``` 4. install llvmlite ```0.41<= version <0.42``` ``` pip uninstall -y llvmlite conda install -y -c numba/label/dev llvmlite ``` >[reference](https://buildmedia.readthedocs.org/media/pdf/llvmlite/latest/llvmlite.pdf) 5. Install Numba from numba channel ``` pip install git+https://github.com/numba/numba.git ```
