Install GroupDocs.Watermark for Python via .NET Leave feedback

GroupDocs.Watermark for Python via .NET is distributed as a pre-built wheel on PyPI. The PyPI index hosts a separate wheel for each supported platform, and pip picks the correct one automatically. Each wheel is self-contained: it bundles the embedded runtime and every managed dependency, so no Microsoft Office, OpenOffice, or separate runtime install is required.

Before you install, review the System Requirements. The wheels need Linux with glibc 2.27 or newer, or macOS 12 or newer, and pip 20.3 or newer to install. On Linux, install ICU, fontconfig, libgdiplus and the Microsoft core fonts; on macOS, install mono-libgdiplus (see Platform Prerequisites).

Open a terminal and run the install command for your platform:

py -m pip install groupdocs-watermark-net

python3 -m pip install groupdocs-watermark-net

python3 -m pip install groupdocs-watermark-net

After running the command you should see output similar to:

Collecting groupdocs-watermark-net

The wheel file name will include a platform suffix that matches your operating system — for example manylinux_2_27_x86_64 on Linux, macosx_12_0_arm64 on Apple Silicon, or win_amd64 on 64-bit Windows.

For reproducible environments, pin the package version in your requirements.txt:

groupdocs-watermark-net==26.10.0

Then install all dependencies in one step:

pip install -r requirements.txt

If your build environment cannot reach PyPI, download the appropriate wheel from the GroupDocs Releases website and install it locally. Wheels are published for the following four platforms:

Since 26.10 the file names state the oldest system each wheel runs on, so pip 20.3 or newer refuses an older one up front instead of installing a runtime that cannot start. Wheels up to 26.6 were tagged manylinux1_x86_64, macosx_10_14_x86_64 and macosx_11_0_arm64.

Place the downloaded wheel into your project folder, then install it:

py -m pip install .\groupdocs_watermark_net-26.10.0-py3-none-win_amd64.whl

python3 -m pip install ./groupdocs_watermark_net-26.10.0-py3-none-manylinux_2_27_x86_64.whl

python3 -m pip install ./groupdocs_watermark_net-26.10.0-py3-none-macosx_12_0_x86_64.whl

python3 -m pip install ./groupdocs_watermark_net-26.10.0-py3-none-macosx_12_0_arm64.whl

Name the wheel file explicitly: PowerShell does not expand a * wildcard for a native command, so pip install groupdocs_watermark_net-*.whl fails there.

Expected output (Linux):

Processing ./groupdocs_watermark_net-26.10.0-py3-none-manylinux_2_27_x86_64.whl

On Windows no extra steps are required. On Linux, install ICU, fontconfig, libgdiplus and the Microsoft core fonts; on macOS, mono-libgdiplus. The System Requirements page lists which features need each one.

# Debian: ttf-mscorefonts-installer is in the contrib component
sudo sed -i '/^Components:/s/main/main contrib/' /etc/apt/sources.list.d/debian.sources
sudo apt-get update
sudo apt-get install -y libicu-dev libfontconfig1 libgdiplus ttf-mscorefonts-installer

brew install mono-libgdiplus

Confirm the package imported correctly and check the installed version:

python -c "import groupdocs.watermark; print('GroupDocs.Watermark is ready')"

You can also list the installed package with pip show groupdocs-watermark-net to confirm the version and location.
