After updating miniconda3, whenever I open a terminal it shows "(base)" in front of my username and host.
In this answer post https://askubuntu.com/a/1113206/315699 it was suggested to use
conda config --set changeps1 False
To remove it.
But that would remove the indication for any conda environment. I would like to remove it only for the base one, so that I can maintain it always active and have access to its python and installed packages without having to always see this (base) taking up space.
That's because conda's base environment is activated on startup.
To set the auto_activate_base parameter to false, type:
conda config --set auto_activate_base false

If you are facing the exact same situation as the OP, that you are using conda to manage environments, and wanted to make (base) environment looks no different to system environment in terminal, check @merv 's answer for the procedures. Note that the prompt string is stored in a certain special variable, depending on the shell you are using, so check the documentation of your shell if it does not work for you.
If you want to use the system environment and not using conda at all, my original answer was the solution for you.
Thanks to @merv and @Neinstein for pointing out in the comments.
Use the base env's activation hook
For each env, any scripts in the etc/conda/activate.d
directory will be executed post-activation (likewise etc/conda/deactivate.d
scripts for deactivation). If you add a script to remove the (base)
, similar to @ewindes suggestion, you'll get the behavior you desire.
I had to create this directory for base, which is just the root of your Anaconda/Miniconda folder. E.g.,
mkdir -p miniconda3/etc/conda/activate.d
Then made a simple file in there (e.g., remove_base_ps1.sh
) with one line:
PS1="$(echo "$PS1" | sed 's/(base) //') "
If you are using zsh, use this instead.
PROMPT=$(echo $PROMPT | sed 's/(base) //')
Launching a new shell then does not show (base)
, and deactivating out of nested envs also takes care of the PS1 change.
Note: You must add quotes around $PS1 if you want to preserve ending spaces.
conda info
in the question.
By default, auto_activate_base
is set to True
when installing anaconda. To check this, run:
$ conda config --show | grep auto_activate_base
auto_activate_base: True
To set it False
conda config --set auto_activate_base False
and vice-versa.
Note, if changeps1
is kept False
, it will hide (env)
completely, and in case you want to show (env)
only when it's activated, you can set changeps1
to True
:
conda config --set changeps1 True
Setting changeps1 to False will hide (env) even if the env is activated and will keep hiding (base) even after auto_activate_base is set to True.
You could add a command to your .bashrc to remove the "(base)" string from PS1:
PS1=$(echo $PS1 | sed 's/(base)//')
PS1
and removes a space after $
, so the text looks like: _rosgori@sa6:~$cd Documents/
. This line improves that: PS1="$(echo $PS1 | sed 's/(base) //') "
, unfortunately, when you activate another env, then deactivate, the (base)
will be there.
If you are a macOS user and recently faced such issue. here is the solution. Just open terminal then type..
conda deactivate
This solution worked for me. As previously I tried some stuffs with anaconda python.
For me, what worked was:
conda config --set changeps1 false
on Debian system, after
conda config --set auto_activate_base false
don't forget in order for effects to take place in the terminal without reloading gnome
bash --login
and verify the status of the flag
conda config --show | grep auto_activate_base
if you are using any destro of Linux
this command will work for you,
conda config --set auto_activate_base false
than
conda deactivate
conda config --set auto_activate_base false
for conda 4.12.0
(under WOS) the following worked (where all the previous answers -these included- didn't do the trick):
in your activate.bat
file (mine was at ~/miniconda3/Scripts/activate.bat), change the line:
@REM This may work if there are spaces in anything in %*
@CALL "%~dp0..\condabin\conda.bat" activate %*
into
@REM This may work if there are spaces in anything in %*
@CALL "%~dp0..\condabin\conda.bat" deactivate
this line chage/modification doesn't work in the section (of the activate.bat file):
@if "%_args1_first%"=="+" if NOT "%_args1_last%"=="+" (
@CALL "%~dp0..\condabin\conda.bat" activate
@GOTO :End
)
maybe because it depends on how your miniconda3
(Anaconda Prompt) executable is set up: %windir%\System32\cmd.exe "/K" some-path-to\miniconda3\Scripts\activate.bat some-path-to\miniconda3
(in my case).
caveat: updating conda
overwrites this (activate.bat) file; so one has to modify the above line as many times as needed/updated. not much of a deal-breaker if you ask me.
Simply comment out all lines in ~/.bashrc, except the environment variable:
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
#__conda_setup="$('/home/<user>/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
#if [ $? -eq 0 ]; then
# eval "$__conda_setup"
#else
# if [ -f "/home/<user>/anaconda3/etc/profile.d/conda.sh" ]; then
# . "/home/<user>/anaconda3/etc/profile.d/conda.sh"
# else
export PATH="/home/<user>/anaconda3/bin:$PATH"
# fi
#fi
#unset __conda_setup
# <<< conda initialize <<<
Maybe it will be because of source active
I had this similar issue when I was doing this in flask server and I activated and forgot to deactivate virtual environment.
So go to the folder that virtual environment is active and type
source deactivate
When using conda and vscode. conda activates the virtual environment in your project if you have one and if not conda and vscode create one for you called base.
to deactivate it, use:
conda deactivate
On my macOS Catalina installation, I just ran conda config --set env_prompt ""
. That removed it for me.
changeps1
would be more effective; this solution still results in running code to manage PS1 even though it only ever inserts empty strings.
Success story sharing
[[ $PS1 =~ ^\(base\) ]] && conda config --set auto_activate_base false
persistent between (re)installations. (Add it into~/.bashrc
, after Conda's section)conda config --set changeps1 false
(base)
prefix hidden for the base environment, this makes the base environment not activate at all. The shell will use the system Python, not the Anaconda one! This is not what OP wants at all, and it will cause a lot of problem for inexperienced users. If you do aconda activate
, the(base)
conda prefix will appear, as you actually load it. The fact this answer has 98+ upvotes show how harmful it is - 98 people thought they solved this problem, while they didn't.
