# conda **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): 1. Télécharger [miniconda](https://docs.conda.io/en/latest/miniconda.html) puis ```bash $ bash Miniconda3-latest-MacOSX-x86_64.sh ``` 2. Télécharger [anaconda](https://www.anaconda.com/distribution/) puis double-cliquer sur le .pkg ##### conda init Initialize conda for shell interaction. (nécessaire pour les commandes `conda activate` et `conda deactivate` ) Shell bash: ```bash $ conda init ``` Ajoute au .bash_profile: ```bash # >>> 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: ```bash $ conda init zsh ``` Ajoute au .zshrc ```bash # >>> 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 .
