conda est le gestionnaire de paquet et d'environnement fourni avec Anaconda.
miniconda est l'installateur de conda. Il installe conda, Python et les paquets de base.
Installer conda:¶
2 façons (miniconda ou anaconda):
- Télécharger miniconda puis
$ bash Miniconda3-latest-MacOSX-x86_64.sh
- Télécharger anaconda puis double-cliquer sur le .pkg
conda init¶
Initialize conda for shell interaction. (nécessaire pour les commandes conda activate et conda deactivate )
Shell bash:
$ conda init
Ajoute au .bash_profile:
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/Users/bruno/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/Users/bruno/miniconda3/etc/profile.d/conda.sh" ]; then
. "/Users/bruno/miniconda3/etc/profile.d/conda.sh"
else
export PATH="/Users/bruno/miniconda3/bin:$PATH"
fi
fi
unset __conda_setup
# <<< conda initialize <<<
Shell zsh:
$ conda init zsh
Ajoute au .zshrc
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/Users/bruno/miniconda3/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/Users/bruno/miniconda3/etc/profile.d/conda.sh" ]; then
. "/Users/bruno/miniconda3/etc/profile.d/conda.sh"
else
export PATH="/Users/bruno/miniconda3/bin:$PATH"
fi
fi
unset __conda_setup
# <<< conda initialize <<<
conda init --reverse¶
Dé-initialise conda
$ conda init --reverse # bash
$ conda init zsh --reverse # zsh
Ajouter miniconda3 au $PATH
export PATH="$HOME/miniconda3/bin:$PATH"
$ which python
/Users/bruno/miniconda3/bin/python
# export PATH="$HOME/miniconda3/bin:$PATH"
$ which python
/usr/local/bin/python
