Install and Use Anaconda on Linux

Install

To Install Anaconda in Ubuntu 22.04, please refer to linuxhint.

The installer has initialized the Anacoda3 in ~/.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/xyu/anaconda3/bin/conda' shell.bash hook 2> /dev/null)"
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/home/xyu/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/home/xyu/anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/home/xyu/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda init <<<

I pasted the code to my ~/.bash_profile in order to make my tmux also initialize the Anacoda3.

Basic Usage

Check and update conda:

conda update conda

Viewing a list of installed packages:

conda list

Viewing a list of existed virtual environment:

conda env list 
conda info -e

Create Python virtual environment:

conda create -n $your_env_name python=x.x

I checked Active Python Release, then created environment of 3.10, 3.9, 3.8 and 3.7 versions.

To activate a environment:

conda activate $your_env_name

To deactivate an active environment:

conda deactivate

To remove a environment:

conda remove -name $your_env_name --all

To remove some package of a environment:

conda remove -name $your_env_name  $package_name

To install a package into your current environment:

conda install $package_name

To install specific a specific version of a package:

conda install $package_name-$version

We can install multiple packages at once.

It is recommended to install all required packages at once so that all of the dependencies are installed at once.

To install a specific package into your existing environment your_env_name:

conda install –name $your_env_name  $package_name

If the package is not available in our conda environment , we can find and install the package with another package manager like pip.

We can install pip in our existing conda environment by simply giving the command:

conda install pip

Problems

VS Code not detecting package in conda environment
