我也遇到过类似的问题，我找到了一个适用于Mac、Windows和Linux的解决方案。它需要上面答案中的几个关键成分:

为了能够看到conda env在Jupyter笔记本，你需要:

the following package in you base env: conda install nb_conda the following package in each env you create: conda install ipykernel check the configurationn of jupyter_notebook_config.py first check if you have a jupyter_notebook_config.py in one of the location given by jupyter --paths if it doesn't exist, create it by running jupyter notebook --generate-config add or be sure you have the following: c.NotebookApp.kernel_spec_manager_class='nb_conda_kernels.manager.CondaKernelSpecManager'

您可以在终端看到的环境:

在Jupyter实验室，你可以看到相同的env上面的笔记本和控制台:

当你打开笔记本时，你可以选择你的环境:

安全的方法是创建一个特定的env，从中运行envjupyter lab命令的示例。激活你的环境。然后添加jupyter实验室扩展示例jupyter实验室扩展。然后你就可以运行木星实验室了

恼人的是，在你的tensorflow环境中，你可以运行jupyter notebook，而无需在该环境中安装jupyter。你就跑

(tensorflow) $ conda install jupyter

tensorflow环境现在应该在Jupyter notebook中可见，在任何conda环境中启动，类似于Python [conda env:tensorflow]。

我不认为其他答案是工作了，因为conda停止自动设置环境作为jupyter内核。您需要手动为每个环境添加内核，方法如下:

source activate myenv
python -m ipykernel install --user --name myenv --display-name "Python (myenv)"

如下所示:http://ipython.readthedocs.io/en/stable/install/kernel_install.html#kernels-for-different-environments 请参见本期。

This has been so frustrating, My problem was that within a newly constructed conda python36 environment, jupyter refused to load “seaborn” - even though seaborn was installed within that environment. It seemed to be able to import plenty of other files from the same environment — for example numpy and pandas but just not seaborn. I tried many of the fixes suggested here and on other threads without success. Until I realised that Jupyter was not running kernel python from within that environment but running the system python as kernel. Even though a decent looking kernel and kernel.json were already present in the environment. It was only after reading this part of the ipython documentation: https://ipython.readthedocs.io/en/latest/install/kernel_install.html#kernels-for-different-environments and using these commands:

source activate other-env
python -m ipykernel install --user --name other-env --display-name "Python (other-env)"

我能让一切顺利进行。(我实际上没有使用-user变量)。

我还没有想到的一件事是如何将默认的python设置为“python (other-env)”。目前，从主屏幕打开的现有.ipynb文件将使用系统python。我必须使用内核菜单“更改内核”来选择环境python。

我们在这个问题上做了很多努力，以下是对我们有效的方法。如果你使用conda-forge通道，确保你使用的是从conda-forge更新的包是很重要的，即使是在你的Miniconda根环境中。

所以安装Miniconda，然后做:

conda config --add channels conda-forge --force
conda update --all  -y
conda install nb_conda_kernels -y
conda env create -f custom_env.yml -q --force
jupyter notebook

你的自定义环境将作为可用的内核显示在Jupyter中，只要你的custom_env中列出了ipykernel以供安装。Yml文件，就像这个例子:

name: bqplot
channels:
- conda-forge
- defaults
dependencies:
- python>=3.6
- bqplot
- ipykernel

为了证明它适用于许多自定义环境，这里有一个Windows屏幕截图:

    $ conda install nb_conda_kernels

(在运行jupyter notebook的conda环境中)将使所有conda envs自动可用。要访问其他环境，必须安装相应的内核。这是裁判。
