Installing Python With Conda

To install Miniconda3, follow the instructions below for Linux. For Windows 11 users, the Windows Subsystem for Linux (WSL) allows you to run Linux within Windows.

# Download the conda install script into a temporary directory
mkdir -p ~/tmp
cd ~/tmp

# To update to a newer version see:
# https://docs.conda.io/en/latest/miniconda_hashes.html for updating
CONDA_INSTALL_SCRIPT=Miniconda3-py310_23.3.1-0-Linux-x86_64.sh
curl https://repo.anaconda.com/miniconda/$CONDA_INSTALL_SCRIPT > $CONDA_INSTALL_SCRIPT

# For security, it is important to verify the hash
CONDA_EXPECTED_SHA256=aef279d6baea7f67940f16aad17ebe5f6aac97487c7c03466ff01f4819e5a651
echo "${CONDA_EXPECTED_SHA256}  ${CONDA_INSTALL_SCRIPT}" > conda_expected_hash.sha256
if ! sha256sum --status -c conda_expected_hash.sha256; then
    echo "Downloaded file does not match hash! DO NOT CONTINUE!"
else
    echo "Hash verified, continue with install"
    chmod +x $CONDA_INSTALL_SCRIPT
    # Install miniconda to user local directory
    _CONDA_ROOT=$HOME/.local/conda
    sh $CONDA_INSTALL_SCRIPT -b -p $_CONDA_ROOT
    # Activate the basic conda environment
    source $_CONDA_ROOT/etc/profile.d/conda.sh
    # Update the base
    conda update --name base conda --yes
fi

NOTE: If using conda, do NOT use conda install to install Python packages.

Create GeoWATCH Environment with Conda

If using conda, the instructions below can be used to create the GeoWATCH Conda environment.

mkdir WATCH_DIR #(pick a name of your choice)
cd WATCH_DIR
git clone https://gitlab.kitware.com/computer-vision/geowatch.git
cd geowatch
conda env create -f conda_env.yml
conda activate geowatch

To deactivate the geowatch environment, run:

conda deactivate

To remove the geowatch environment, run:

conda deactivate #(if geowatch is activated before)
conda remove --name geowatch --all

To update the geowatch environment when new packages have been added, run:

conda activate geowatch
conda env update -f deployment/conda/conda_env.yml
