If you want to use the
conda command type
ENTER and you’ll be presented the following output:
Appending source /home/black/anaconda3/bin/activate to /home/black/.bashrc A backup will be made to: /home/black/.bashrc-anaconda3.bak For this change to become active, you have to open a new terminal. Thank you for installing Anaconda3!
The installer will also ask you whether you would like to download and install Visual Studio Code.
Anaconda is partnered with Microsoft! Microsoft VSCode is a streamlined code editor with support for development operations like debugging, task running and version control. To install Visual Studio Code, you will need: - Administrator Privileges - Internet connectivity Visual Studio Code License: https://code.visualstudio.com/license Do you wish to proceed with the installation of Microsoft VSCode? [yes|no]
To activate the Anaconda installation load the new
PATH environment variable which was added by the Anaconda installer into the current shell session with the following command:
Verify the Installation
You can verify your Anaconda installation using the
conda command. For example to display information about current conda install type:
active environment : base active env location : /home/black/anaconda3 shell level : 1 user config file : /home/black/.condarc populated config files : conda version : 4.5.11 conda-build version : 3.15.1 python version : 3.7.0.final.0 base environment : /home/black/anaconda3 (writable) channel URLs : https://repo.anaconda.com/pkgs/main/linux-64 https://repo.anaconda.com/pkgs/main/noarch https://repo.anaconda.com/pkgs/free/linux-64 https://repo.anaconda.com/pkgs/free/noarch https://repo.anaconda.com/pkgs/r/linux-64 https://repo.anaconda.com/pkgs/r/noarch https://repo.anaconda.com/pkgs/pro/linux-64 https://repo.anaconda.com/pkgs/pro/noarch package cache : /home/black/anaconda3/pkgs /home/black/.conda/pkgs envs directories : /home/black/anaconda3/envs /home/black/.conda/envs platform : linux-64 user-agent : conda/4.5.11 requests/2.19.1 CPython/3.7.0 Linux/3.10.0-957.1.3.el7.x86_64 centos/7 glibc/2.17 UID:GID : 0:0 netrc file : None offline mode : False
Updating the Anaconda is a pretty straight forward process, first update the conda tool with:
conda update conda
When prompted to confirm the update, type
y to proceed.
Once conda is updated, proceed with the Anaconda update:
conda update anaconda
Same as with the previous command, when prompted, type
y to proceed.
You should regularly update your Anaconda installation.
If you want to uninstall Anaconda from your CentOS system, follow the steps below:
Remove the Anaconda install directory.
To remove the entire Anaconda installation directory type:
rm -rf ~/anaconda3
Edit the PATH environment variable.
~/.bashrc file and remove the code added by the Anaconda installer:~/.bashrc
# added by Anaconda3 5.3.1 installer # >>> conda init >>> # !! Contents within this block are managed by 'conda init' !! __conda_setup="$(CONDA_REPORT_ERRORS=false '/home/black/anaconda3/bin/conda' shell.bash hook 2> /dev/null)" if [ $? -eq 0 ]; then \eval "$__conda_setup" else if [ -f "/home/black/anaconda3/etc/profile.d/conda.sh" ]; then . "/home/black/anaconda3/etc/profile.d/conda.sh" CONDA_CHANGEPS1=false conda activate base else \export PATH="/home/black/anaconda3/bin:$PATH" fi fi unset __conda_setup # <<< conda init <<<
Remove the hidden files.
The following command will remove the hidden files and folders that have been created in your user home directory:
rm -rf ~/.condarc ~/.conda ~/.continuum
