I have used pip to install orange and the installation seemed fine. There was not Orange icon on my ubuntu 16.04 desktop and tried orange3 in the command line, it didn't work, and tried python3 -m orange and python3 -m orange 3 and neither worked as well.
How can I use orange?
From the Orange3 Pypi documentation :
To start Orange GUI from the command line, assuming it was successfully installed, run:
orange-canvas # or python3 -m Orange.canvas
You should fire up a python console and try import orange.
If it doesn't give you any errors then the installation succeeded.
For the GUI, try something like:python /usr/local/lib/python2.7/dist-packages/Orange/OrangeCanvas/orngCanvas.pyw (change python version)
Using Anaconda
If you are using python provided by Anaconda distribution, you are almost ready to go. Add conda-forge to the list of channels you can install packages from
conda config --add channels conda-forge
and install packages
conda install orange3 conda install -c defaults pyqt=5 qt
Now create the conda environment named orange3
conda create python=3 orange3 --name orange3
Activate the environment, run orange3 and finally deactivate it
conda activate orange3 python3 -m Orange.canvas conda deactivate
Moreover, you probably have Anaconda Navigator (the graphical interface to conda) in anaconda3 . Why not using it ?
cd home/anaconda3/bin ./anaconda-navigator
Now the graphical interface to conda starts, then choose the orange3 environment, and run orange3
