Jupyter Notebook doesn’t recognise Anaconda installation

问题

由于某种原因,Jupyter不识别Anaconda安装。

import os
result = os.popen('conda list anaconda$').read()
print('\nAnaconda版本:\n', result)

结果:

Anaconda版本:
在C:\Users\Andy\anaconda3环境中的软件包:

名称 版本 构建 频道

我已经更新了Windows路径变量如下:

C:\Users\Andy\anaconda3;
C:\Users\Andy\anaconda3\Scripts

conda.exe应用程序位于Scripts目录中

提前感谢任何帮助

编辑...

运行以下命令后的前10(左右)行:

conda list

结果如下:

C:\Users\Andy\anaconda3环境中的软件包:
注意:您可能需要重新启动内核以使用更新的软件包。

For some reason Jupyter won't recognise the Anaconda installation

import os
result = os.popen('conda list anaconda$').read()
print('\nAnaconda Version:\n', result)

Result:

Anaconda Version:
packages in environment at C:\Users\Andy\anaconda3:

Name Version Build Channel

I've updated the Windows Path variables as follows

C:\Users\Andy\anaconda3;
C:\Users\Andy\anaconda3\Scripts

The conda.exe application is in the Scripts directory

Thanks in advance for any help

Edit...

The top 10(ish) rows from running

conda list

are

# packages in environment at C:\Users\Andy\anaconda3:
Note: you may need to restart the kernel to use updated packages.

使用Jupyter,在笔记本中的一个单元格中运行以下内容:

%%capture out
%conda list anaconda$

(这将将%conda list的结果发送到out,其类型为IPython.utils.capture.CapturedIO。您可以在这里的IPython.utils.capture.CapturedIO文档中了解如何访问其各种属性。下面我将介绍如何处理它并解析出您想要的版本信息。)

然后,在下一个单元格中,您可以解析收集到的信息:

out.stdout.split("Channel")[1].split("anaconda", 1)[1].split()[0]

根据您在上面的评论中发布的内容,您应该看到:

2023.07

当我运行它时,我实际上看到的是2022.05


您最初发布的尝试os.popen('conda list anaconda$').read()是通过os将您的命令发送到临时系统 shell,因此可能不在运行Jupyter的内核所在的确切环境中。%conda list使用魔术命令确保在运行Jupyter的内核所在的相同环境中运行。

英文:

Using Jupyter, run in a cell in your notebook the following:

%%capture out
%conda list anaconda$

(That sends the result of the %conda list to out, which is of the type IPython.utils.capture.CapturedIO. You can read about accessing the various attributes of that here in the IPython.utils.capture.CapturedIO documentation. I cover here how I handle it and parse out the version information I think you want next.)

Then in the next cell, you can parse collected the information:

out.stdout.split("Channel")[1].split("anaconda",1)[1].split()[0]

Based on what you posted in a comment above, you should see:

2023.07

I actually see 2022.05 when I run it.


Your original posted attempt os.popen('conda list anaconda$').read() is sending your command to a temporary system shell via os, and so that may not be in the exact environment where you notebook kernel is running. %conda list uses the magic command to insure things run in the same environment where your kernel backing Jupyter runs.
