运行 Raspberry Pi 3 上的 Numba Jit

Question

我想 运行 一个带有 numba 的 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 运行 使用 @jit 装饰器的程序时，它告诉：

尝试更新 numba 和 llvmlite references from git numba

conda install -c numba llvmlite
