在 jetson xavier nx 上为 python2 安装 llvmlite 和 numba 库

Question

我想在 jetson 上为 python2 安装 numba 和 llvmlite。但是似乎没有相同的文档。一切都是为了 python3。我正在尝试运行 ros melodic 上的程序，因此需要 python2 中的库。当我尝试

python2.7 -m pip install numba==0.45

我收到以下错误

Answer 1

尝试升级 pip 并安装支持 Python 2.7 的最新版本：

python2.7 -m pip install -U "pip < 21.0"
python2.7 -m pip install "llvmlite < 0.32.1" "numba < 0.46"

Answer 2

我解决了

对我有用的是

sudo apt-get install python-numba

在 jetson xavier nx 上为 python2 安装 llvmlite 和 numba 库

install llvmlite and numba library for python2 on jetson xavier nx

python

python-2.7

pip
