我从一个anaconda环境打开了一个jupyter笔记本,但是内核使用的是默认版本的python,而不是在这个环境中定义的python(它包含我安装的所有包)。在
我怎样才能改变它?在

我用的是MAC。在
在环境中安装jupyter后:

您正在使用安装在水蟒主安装路径(
/Users/okoub/anaconda3/lib/python3.6/site-packages/jupyterlab
)中的jupyter。如果要在环境中使用jupyter,请将其安装到所需的env中。在如果您已经在您的环境中安装了jupyter,请不要忘记在运行jupyter notebook之前激活它。在
抱歉,我不知道激活conda环境的方式是否与Linux相同
以下操作编辑:
看起来您在
prompt_toolkit
中出错。你能试着用康达重新安装吗?在运行
conda install nb_conda_kernels
,然后重新启动jupyter
。现在,在右上角应该有一个额外的选项来选择笔记本应该使用哪个conda env
来执行代码。这是IMO最方便的解决方案,因为您可以在同一个项目中拥有多个笔记本电脑,它们可以在各自的环境下运行,而不必一直source activate
