在Jupyter笔记本中使用conda环境

Question

我在Windows 10上运行Anaconda，并使用Jupyter Notebook进行机器学习项目。

我最近开始意识到Conda中的虚拟环境。

我使用以下命令在conda中创建了一个虚拟环境

conda create -n test1

激活环境

activate test1

ipykernel中安装的环境（不确定使用的术语是否正确）

python -m ipykernel install --user --name test1

现在环境test1是可见的jupyter笔记本，但当我启动它我得到内核启动...

下面是一些片段。

同样在jupyter提示符中（同样不确定术语），我得到了以下错误

我想做的就是在jupyter笔记本中使用新创建的环境。

请尝试以下步骤：

source activate test1
conda install ipykernel
ipython kernel install --name test1 --user
