Python jupyter笔记本中的切换环境问题（开放或新）

我正在尝试使用特定的jupyter环境来运行笔记本。理想情况下，我希望能够从jupyter中选择环境，但我会在这一点上满足于能够让环境正常工作如何让笔记本识别另一个环境，或者在该环境中启动，或者在启动笔记本后选择它？

右上角下拉菜单上的环境名称将更改，但环境似乎未激活。笔记本上也没有显示我开始jupyter实验室时所处的环境。以下是我尝试过的：

我正在通过ssh路由的linux服务器上运行此笔记本

我使用conda安装了多个环境，并使用.yml文件创建：

base                     /FILEPATH/anaconda3
jupyter_env           *  /FILEPATH/anaconda3/envs/jupyter_env
science_env        /FILEPATH/anaconda3/envs/science_env

我激活了jupyter_env。 我运行此命令以将其他环境添加到笔记本中（或者我认为是这样）：

我开了一个jupyter实验室

jupyter lab --port 7989 --no-browser &

并打开新笔记本或现有笔记本。我可以在下拉框的右上角看到“science_env”，我可以选择它

然而，如果我尝试导入一个在science_env中的包，它就会失败。 此外，如果我打开该笔记本的内核并键入“conda info”，它仍然会显示：

active environment : jupyter_env

只是为了检查是否安装了所需的软件包： 在终端窗口中，当我使用“conda list”显示环境中的内容时，我看到jupyter_env包括（I-j范围内列表的相关部分，底部为完整列表）：

在science_envs中，我已经列出了相同的范围（太长了，无法列出整个列表-如果有人认为它相关，我可以稍后再添加）：

如果我激活science_env环境，然后启动jupyter lab，它仍然不工作。如果我在jupyter笔记本的控制台中执行“conda list”，它不会像从命令行执行conda list一样列出相同的包。该列表似乎与我的基本安装相匹配，而与我的任何环境都不匹配如何让笔记本识别另一个环境，或者在该环境中启动，或者在启动笔记本后选择它？

我还试着为我实验室的另一位成员设置这个，他们也有同样的问题。有人能帮我看看为什么这不起作用吗
