openvisuspy 1.0.7

openvisuspy

OpenViSUS Visualization project

The official OpenVisus C++ GitHub repository is here.

Install openvisuspy

Create a virtual environment. This step is optional, but best to avoid conflicts:

• for windows users you can do doskey python3=python $* and .venv/Scripts/activate.bat

python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install --upgrade pip

Install python packages, technically only numpy is stricly needed, but to access cloud storage and show dashboards/notebooks, you need additional packages too.

python3 -m pip install numpy boto3 xmltodict colorcet requests scikit-image matplotlib bokeh panel itkwidgets[all] pyvista vtk jupyter

Next, nstall Openvisus packages.

If you do not need the OpenVisus viewer (or if you are in Windows WSL):

python3 -m pip install --upgrade OpenVisusNoGui
python3 -m pip install --upgrade openvisuspy 

if you do need the OpenVisus viewer:

python3 -m pip install --upgrade OpenVisus
python3 -m OpenVisus configure 
python3 -m pip install --upgrade openvisuspy 

if you are in debugging mode you may want to reference your local packages:

export PYTHONPATH=./src;/projects/OpenVisus/build/RelWithDebInfo
