问题描述

I have a conda environment that is running python 3.10.5.我有一个运行 python 3.10.5 的 conda 环境。 It works on the terminal without screen.它在没有屏幕的终端上工作。 First I did首先我做了

conda deactivate

And conda info at this step shows:此步骤的conda info显示：

     active environment : base
    active env location : /home/myuser/anaconda3
            shell level : 1
       user config file : /home/myuser/.condarc
 populated config files : 
          conda version : 4.13.0
    conda-build version : 3.21.8
         python version : 3.9.12.final.0
       virtual packages : __cuda=10.2=0
                          __linux=5.4.0=0
                          __glibc=2.27=0
                          __unix=0=0
                          __archspec=1=x86_64
       base environment : /home/myuser/anaconda3  (writable)
      conda av data dir : /home/myuser/anaconda3/etc/conda
  conda av metadata url : None
           channel URLs : https://repo.anaconda.com/pkgs/main/linux-64
                          https://repo.anaconda.com/pkgs/main/noarch
                          https://repo.anaconda.com/pkgs/r/linux-64
                          https://repo.anaconda.com/pkgs/r/noarch
          package cache : /home/myuser/anaconda3/pkgs
                          /home/myuser/.conda/pkgs
       envs directories : /home/myuser/anaconda3/envs
                          /home/myuser/.conda/envs
               platform : linux-64
             user-agent : conda/4.13.0 requests/2.27.1 CPython/3.9.12 Linux/5.4.0-109-generic ubuntu/18.04.6 glibc/2.27
                UID:GID : 1001272705:1000000513
             netrc file : None
           offline mode : False

then I did然后我做了

screen -S scren_name

and the conda info at this step is这一步的conda info是

     active environment : base
    active env location : /home/myuser/anaconda3
            shell level : 1
       user config file : /home/myuser/.condarc
 populated config files : 
          conda version : 4.13.0
    conda-build version : 3.21.8
         python version : 3.9.12.final.0
       virtual packages : __cuda=10.2=0
                          __linux=5.4.0=0
                          __glibc=2.27=0
                          __unix=0=0
                          __archspec=1=x86_64
       base environment : /home/myuser/anaconda3  (writable)
      conda av data dir : /home/myuser/anaconda3/etc/conda
  conda av metadata url : None
           channel URLs : https://repo.anaconda.com/pkgs/main/linux-64
                          https://repo.anaconda.com/pkgs/main/noarch
                          https://repo.anaconda.com/pkgs/r/linux-64
                          https://repo.anaconda.com/pkgs/r/noarch
          package cache : /home/myuser/anaconda3/pkgs
                          /home/myuser/.conda/pkgs
       envs directories : /home/myuser/anaconda3/envs
                          /home/myuser/.conda/envs
               platform : linux-64
             user-agent : conda/4.13.0 requests/2.27.1 CPython/3.9.12 Linux/5.4.0-109-generic ubuntu/18.04.6 glibc/2.27
                UID:GID : 1001272705:1000000513
             netrc file : None
           offline mode : False

then I activated the environment in screen.然后我在屏幕中激活了环境。 Now conda info says现在conda info说

     active environment : catvehicle
    active env location : /home/myuser/anaconda3/envs/catvehicle
            shell level : 2
       user config file : /home/myuser/.condarc
 populated config files : 
          conda version : 4.13.0
    conda-build version : 3.21.8
         python version : 3.9.12.final.0
       virtual packages : __cuda=10.2=0
                          __linux=5.4.0=0
                          __glibc=2.27=0
                          __unix=0=0
                          __archspec=1=x86_64
       base environment : /home/myuser/anaconda3  (writable)
      conda av data dir : /home/myuser/anaconda3/etc/conda
  conda av metadata url : None
           channel URLs : https://repo.anaconda.com/pkgs/main/linux-64
                          https://repo.anaconda.com/pkgs/main/noarch
                          https://repo.anaconda.com/pkgs/r/linux-64
                          https://repo.anaconda.com/pkgs/r/noarch
          package cache : /home/myuser/anaconda3/pkgs
                          /home/myuser/.conda/pkgs
       envs directories : /home/myuser/anaconda3/envs
                          /home/myuser/.conda/envs
               platform : linux-64
             user-agent : conda/4.13.0 requests/2.27.1 CPython/3.9.12 Linux/5.4.0-109-generic ubuntu/18.04.6 glibc/2.27
                UID:GID : 1001272705:1000000513
             netrc file : None
           offline mode : False

However, when I write python in screen, the version shown is the default Ubuntu 18.04 included python which is 2.7, and not the 3.10.5 version that was part of my conda env.但是，当我在屏幕上编写python时，显示的版本是默认的 Ubuntu 18.04 包含的 python 2.7，而不是我的 conda env 中的 3.10.5 版本。

how can I fix this, or make it use the proper python?我该如何解决这个问题，或者让它使用正确的python？

Edit: as mentioned by other users, setting an alias is not recommended.编辑：正如其他用户所提到的，不建议设置别名。 I was able to fix it by:我能够通过以下方式修复它：

  1. Entering screen进入画面
  2. Writing conda deactivate until the (base) environment was no longer activated either.编写conda deactivate直到(base)环境也不再被激活。
  3. Writing conda activate my_env to activate.编写conda activate my_env来激活。

Now the python path is correct.现在python路径是正确的。
