Installation¶

numba can be installed using the following command.

:::bash
pip3 install numba

If you need CUDA support, you have to install CUDA drivers.

:::bash
sudo apt-get install cuda-10-1

Instead of going through the hassle of configuring numba for GPU, a better way is to run numba in a Nvidia Docker container. The Docker image nvidia/cuda:10.1-cudnn7-runtime-ubuntu18.04 has CUDA runtime installed, so it is as easy as installing numba on top it and you are ready to go.

Tips and Traps¶

1. It is never a good idea to do pre-mature optimization. Always profile (please refer to Profile Performance of Python Applications and Python Profiler for JupyterLab Notebooks) your code before you optimize it. If you do decide to optimize you Python code, there are multiple approaches. First, think about whether you can improve your algorithm. Please refer to Python Performance Tips
