The exact wheel name depends on your OS and CPU architecture — see the wheel-suffix table in System Requirements for the complete list.
Add the Package to requirements.txt
Add the dependency to your project’s requirements.txt:
groupdocs-viewer-net
Then install from the file:
pip install -r requirements.txt
Pin to a specific version if you need reproducible builds — for example, groupdocs-viewer-net==26.9.0.
Install from a Pre-Downloaded Wheel
For air-gapped or controlled environments, download the wheel from the GroupDocs Releases site or the PyPI release page and install it directly. Four platform-specific wheels are published per release; pick the one that matches your host:
Windows x86-64 — groupdocs_viewer_net-<version>-py3-none-win_amd64.whl
Linux x86-64 — groupdocs_viewer_net-<version>-py3-none-manylinux_2_27_x86_64.whl (glibc 2.27 or newer)
macOS Apple Silicon (ARM64) — groupdocs_viewer_net-<version>-py3-none-macosx_12_0_arm64.whl (macOS 12 or newer)
macOS Intel (x86-64) — groupdocs_viewer_net-<version>-py3-none-macosx_12_0_x86_64.whl (macOS 12 or newer)
Since 26.9 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 26.5 were tagged manylinux1_x86_64, macosx_10_14_x86_64 and macosx_11_0_arm64.
Copy the downloaded wheel into your project folder and install it with pip:
