<syntaxhighlight lang="bash">

== Best Practices ==
 
== Update Python version for the conda env using mamba and yaml file ==
<syntaxhighlight lang="bash">
# environment.yml to update package inside of your environment
channels:
  - conda-forge
  - nodefaults
dependencies:
  - python >=3.10,<3.11
  - jupyterlab
  - numpy
  - scikit-learn
  - matplotlib-base # avoid qt if you can, if having trouble
 
$mamba env update -n <your env> --file environment.yml
</syntaxhighlight>
 
== Basic conda/mamba env setup in [[Manual:DLSSystem|DLS framework]] <ref>https://docs.conda.io/projects/conda/en/stable/commands/config.html</ref> ==
<syntaxhighlight lang="bash">
conda config --set auto_activate_base false
conda config --add channels r
conda config --add channels defaults
conda config --add channels bioconda
conda config --add channels conda-forge
</syntaxhighlight>
 
== How to fix InsecureRequestWarning: Unverified HTTPS request is being made to host ==
conda config --set ssl_verify false
 
== conda: error: argument COMMAND: invalid choice: 'actiate' ==
<syntaxhighlight lang="bash">
# Try activate base
$ source activate base
# Then deactivate it
(base) $ conda deactivate
 
# after then you can use activate command
$ conda activate base
</syntaxhighlight>


== Downgrading Conda Version ==
* 최신 버전 사용 권장
<syntaxhighlight lang="bash">
* 공식 문서 참고
conda config --set allow_conda_downgrades true
* 테스트 환경에서 먼저 검증
conda install conda=a.b.c  # version you want to install
</syntaxhighlight>
