Install OpenVisus
You need a conda
installation. For Windows, go to this link and follow instructions. At the end you will have an Anacronda Prompt
. On OSX you can use brew install
or:
curl -O https://repo.anaconda.com/archive/Anaconda3-2020.07-MacOSX-x86_64.sh
bash Anaconda3-2020.07-MacOSX-x86_64.sh
On Linux:
curl -O https://repo.anaconda.com/archive/Anaconda3-2019.03-Linux-x86_64.sh
bash Anaconda3-2019.03-Linux-x86_64.sh
(OPTIONAL) To avoid conflicts with CPython installations:
conda config --set auto_activate_base false
Then activate conda:
conda activate
For OSX and Linux you may need to add this variable to avoid conflicts with pip
CPython installed packages in ~/.local
(see this link for more info):
export PYTHONNOUSERSITE=True
Open a Windows Anaconda prompt
or a shell and type (change python version and env name as needed):
conda create -n myenv python=3.7
conda activate myenv
conda install --name myenv -y conda
conda install --name myenv -y --channel visus openvisus
Test it (just ignore segmentation fault error on some Linux distributions in the configure
step): If you would like to use conda for the rest of the configuration, create an environment variable: USE_CONDA=1
Otherwise, by default, the configuration process will use pip.
python -m OpenVisus configure
python -c "from OpenVisus import *"
(OPTIONAL) If you get numpy import error such as Library not loaded: @rpath/libopenblas.dylib
, this:
conda uninstall --name myenv -y numpy
conda install --name myenv -y nomkl numpy scipy scikit-learn numexpr openblas blas
conda remove --name myenv -y mkl mkl-service
python -c "import numpy"
Run the viewer:
python -m OpenVisus viewer
(OPTIONAL) Remove the enviroment:
conda deactivate
conda remove --name myenv --all
