在 Raspberry Pi 3 上运行 Numba Jit

Question

我想用 numba 运行一个 python 程序。 我尝试使用以下方法安装 numba：

sudo apt install libblas-dev llvm python3-pip python3-scipy
sudo pip install llvmlite==0.15.0
sudo pip install numba==0.30.1

并搜索其他参考以安装 numba。 Numba 可以导入，但是当我用 @jit 装饰器运行程序时，它告诉：

尝试更新numba和llvmlitereferences from git numba

conda install -c numba llvmlite
