Linux jupyter笔记本电脑可以'；t仅在引导时检测conda内核

我正在尝试在启动时自动启动jupyter服务器。（ec2，亚马逊linux）

我让jupyter服务器正常工作并正确加载了所有conda内核

我试着用靴子跑jupyter。（尝试了rc.local、systemd、crontab和all无法加载conda内核，只能加载基本的python2和python3内核）

我将其追溯到nb_conda_内核无法在启动时调用“conda”，如下所示：

最奇怪的是，当我用“sudo ss--tulpn|grep 8888”（为正在侦听端口8888的jupyter笔记本查找pid）和“sudo kill-9{pid}”（杀死进程。检查我是否成功杀死了它）杀死正在运行的服务器时，我通过boot中使用的相同命令重新启动服务器，然后jupyter成功加载conda内核，如下所示：

关于这个问题，我在stackoverflow上看到了一个特别的问题。() 但这里的问题是，当我键入“jupyter内核规范列表”时，我只得到python3和python2，即使jupyter已经成功加载了conda内核

python3    /home/ec2-user/anaconda3/share/jupyter/kernels/python3
  python2    /usr/share/jupyter/kernels/python2

此外，我还尝试在jupyter配置文件中更改environmentspecmanager，看看它是否解决了问题，但没有。（同一错误日志，“无法调用conda”）

这里有什么问题？

conda

在执行rc.local时尚未配置。这通常通过

.bashrc

文件完成。但您可以尝试将其添加到

rc.local

脚本中（在启动jupyter之前）：

---

这应该设置在执行rc.local时尚未配置conda

conda

的使用。这通常通过

.bashrc

文件完成。但您可以尝试将其添加到

rc.local

脚本中（在启动jupyter之前）：

这将设置conda的使用

谢谢你，FlyterTeller。我在rc.local中使用了下面的代码，而不是您显示的代码

if [ -f "/home/ec2-user/anaconda3/etc/profile.d/conda.sh" ]; then
    . "/home/ec2-user/anaconda3/etc/profile.d/conda.sh"
    CONDA_CHANGEPS1=false /home/ec2-user/anaconda3/bin/jupyter notebook --config /home/ec2-user/.jupyter/jupyter_notebook_config.py --allow-root --no-browser
fi

---

但在执行rc.local时没有配置conda是正确的。谢谢你把我推向正确的方向，所以我投票接受你的答案
