问题描述

我使用软件包remote_ikernel从azure VM自动连接到azure VM.这两个系统是相同的,也就是说,它们具有相同的python环境.

I use the package remote_ikernel to automatically connect to an azure VM from an azure VM. The two systems are identical, that is, they have the same python environments.

我使用

ssh -oStrictHostKeyChecking=no {username}@{ip} sudo /anaconda/envs/py36/bin/ipython kernel

然后通过在下面的脚本中填充参数来更新我的本地kernel.json.

And then update my local kernel.json by filling the parameters in the script below.

        {{
    "argv": [
        "/anaconda/envs/py35/bin/python",
        "-m",
        "remote_ikernel",
        "--interface",
        "ssh",
        "--host",
        "{username}@{ip}",
        "--kernel_cmd",
        "/anaconda/envs/{remote_python}/bin/ipython kernel -f {{host_connection_file}}",
        "{{connection_file}}"
    ],
    "display_name": "SSH {username}@{kernel_name}",
    "remote_ikernel_argv": [
        "/anaconda/envs/py35/bin/remote_ikernel",
        "manage",
        "--add",
        "--kernel_cmd=/anaconda/envs/{remote_python}/bin/ipython kernel -f {{connection_file}}",
        "--name=Remote VM",
        "--interface=ssh",
        "--host={username}@{ip}"
    ]
}}

首次尝试但是,我们不想使用远程/anaconda/envs/py35/bin/python,而是使用它的py36兄弟.我希望通过在第一个命令中对其进行调整来解决该问题,但这并不能解决问题.它也无助于更改kernel.json中的任何py35.我们如何实现这一目标?

First attemptHowever, we don't want to use the remote /anaconda/envs/py35/bin/python but its py36 brother. I hoped to solve that by adjusting it in the 1st command, but that doesn't solve it. It also didn't help to change any of the py35 in the kernel.json. How can we achieve that?

第二次尝试(编辑)我修改了kernel.json以包含指向py36环境的指针.请参阅上面的更新版本.下面的日志看起来不错,但是import sys; sys.executable仍显示py35版本.

Second attempt (edit)I adapted the kernel.json to include the pointer to the py36 environment. See the updated version above. The log below looks fine, but import sys; sys.executable still shows the py35 version.

推荐答案

不确定是否仍然有用,以防万一:
添加内核时,请使用--remote-precmd选项.
根据文档:

Not sure if it's still relevant but just in case:
Use the --remote-precmd option when adding your kernel.
According to the docs:

您可以使用此选项激活所需的环境:

You can use this option to activate your needed env:

--remote-precmd=source %PathToVenv%/Scripts/activate

我正在使用它,它可与remote_ikernel v0.4.6一起使用,而我的遥控器是Windows10.

I'm using it and it works with remote_ikernel v0.4.6 and my remote is Windows 10.

对于Windows,该命令应如下所示:

For Windows, the command would be something like this:

--remote-precmd=%PathToVenv%\\Scripts\\activate.bat
