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]。

我只是想补充之前的答案:如果安装nb_conda_kernels, ipywidgets和ipekernel不能工作，请确保您的Jupyter版本是最新的。我的envs在一切正常工作一段时间后突然停止显示，并在我简单地通过anaconda navigator更新jupyter后恢复工作。

我不得不运行前3个答案中提到的所有命令来让它工作:

conda install jupyter
conda install nb_conda
conda install ipykernel
python -m ipykernel install --user --name mykernel

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。

首先你需要激活你的环境。

pip install ipykernel

接下来，您可以通过输入以下命令将虚拟环境添加到Jupyter:

python -m ipykernel install --name = my_env
