在 Jupyter Notebook 中使用 conda 环境

Question

我在运行 Anaconda windows 10 上使用 Jupyter Notebook 进行我的机器学习项目。

我最近开始了解 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 中的安装环境（不确定使用的术语是否正确）

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

现在环境 test1 在 jupyter notebook 中可见，但是当我启动它时我收到 kernel starting... please wait 消息。

这里有一些片段。

同样在 jupyter 提示符下（再次不确定条款）我收到以下错误

我只想在 jupyter notebook 中使用新创建的环境。

Answer 1

请尝试以下步骤：

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

在 Jupyter Notebook 中使用 conda 环境

Use conda environment in Jupyter Notebook

anaconda

conda

virtual-environment

jupyter-notebook
