带optirun的IPython笔记本电脑

Question

我想从IPython笔记本电脑上用nvidiaoptimus（大黄蜂）在Linux笔记本上运行pycuda。通常，我可以通过输入optirun python my_pycuda_script.py来运行python脚本

但是如果我启动optirun ipython notebook然后打开一个笔记本，一个新的内核就会启动，我就不能再运行pycuda了。{I发现这是一个很难看的脚本，但我发现这个脚本很难看。有更好的方法吗？也许有一个神奇的功能，所以只有相关的笔记本电脑才用optirun启动？在

谢谢你的帮助！在

我刚从github:data_science_workspace找到了一个解决方案。在

GPU support for Jupyter:

For computers on linux with optimus, you have to make a kernel that will be called with "optirun" to be able to use GPU acceleration. For this go to the following folder:

cd ~/.local/share/jupyter/kernels/

then edit the file python3/kernel.json in order to add "optirun" as first entry into the argv array:

{
"language": "python",
"display_name": "Python 3",
"argv": [
    "optirun",
    "/home/fabien/.conda/envs/data_science/bin/python",
    "-m",
    "ipykernel",
    "-f",
    "{connection_file}"
    ]
}

但是在我的电脑里，kernel.json在：~/miniconda3/envs/nn/share/jupyter/kernels/python3下面。在
