Installation

For conda see docs/conda-installation.md.

Make sure pip is installed, updated and in PATH.

pip install --upgrade OpenVisus
# configure OpenVisus (one time)
python -m OpenVisus configure 
# test installation
python -c "from OpenVisus import *"

Notes:

if you get permission denied error, use pip install --user.
if you need a minimal installation without the GUI replace OpenVisus with OpenVisusNoGui
If you want to create an isolated virtual environment with virtualenv:

# make sure venv is latest
pip install --upgrade virtualenv
# create a virtual environment in current directory
venv ./ovenv
# activate the virtual environment
source ./ovenv/bin/activate

Run the OpenVisus viewer:

python -m OpenVisus viewer

Handle with PyQt errors

Sometimes, PyQt (or other packages like pyqt5-sip) is already installed in system and OpenVisus viewer gets confused which package to use.

To solve that issue, follow these steps before main installation:

If on linux, make sure PyQt5 or any of it's related packages are not installed system-wide.
- For Ubuntu use sudo apt remove python3-pyqt5 to remove pyqt5 and all other related packages listed here.
- For any Arch based distro, use sudo pacman -Rs python-pyqt5. Same for all other packages like python-pyqt5-sip.
Remove all pyqt5 packages with pip:
- pip uninstall pyqt5 PyQt5-sip
