INSTALLATION

We are proceding in three main steps

• installation of a virtual environments
• installation of Orange
• installation of the shadok add-on for Orange
• installation of the XRStools library
• video tutorials

Setting up the virtual env

preliminary cleaning and setting of some environment variable

unset LD_LIBRARY_PATH
unset LDFLAGS
unset CPPFLAGS
unset PYTHONPATH

You need also to have installed the packages: python3, python3-dev,python3-pyqt4 If you are behind a firewall you will need this to load external packages

export http_proxy=http://XXX.YYY.ZZZ:1234
export https_proxy=https://XXX.YYY.ZZZ:1234
(At ESRF ask to the TID for the exact location of the proxy)

Moreover, in order to be able to install packages from server which are from the same side of the firewall

export no_proxy="localhost,.esrf.fr"

CREAZIONE DEL VIRTUAL ENV

Orange3 needs python3, so we are going to create a virtualenv using python3. This will also contain all the packages that we are going to install. This packages will be used only when our virtualEnv will be activated. Create a new virtualEnv

virtualenv --python=python3 ~/software/virtualenvOrangeShadok

Activate the virtualEnv

source ~/software/virtualenvOrangeShadok/bin/activate

now the virtual env is activated, your PATH now allows to use a special python3 which will load prioritarily the packages of the virtual env. There remains a trick for some Qt library which otherwise would be cumbersome to install

ln -s /usr/lib/python3/dist-packages/sip*   ~/software/virtualenvOrangeShadok/lib/python3.4/site-packages/
ln -s /usr/lib/python3/dist-packages/PyQt4  ~/software/virtualenvOrangeShadok/lib/python3.4/site-packages/

We are going to install some packages from sources, therefore now we need to upgrade the installation tools

pip install setuptools --upgrade

upgrade also pip with the lastest version (needs the proxy working correctly if you are behind a fw)

pip install pip --upgrade

On ubuntu install manually numpy because it will be necessary for the following installations

pip install numpy

INSTALLATION OF ORANGE

Create a directory for the sources and download them

makedir ~/software/

download the customised Orange sources

cd ~/software
git clone https://github.com/alemirone/orange3.git
cd orange3

Now we are going to install the orange package, as this will trigger the automatic download of dependencies. give the installation command

pip install -r requirements.txt
pip install -r requirements-gui.txt

and now you can install Orange ::

  pip install .

Now test if the orange-canvas pops-up

orange-canvas -l 4

The -l 4 switch turns on the verbosity to level 4 ( a lot of messages are displayed)

INSTALLATION OF THE SHADOK ADD-ON

Download the sources

cd ~/software
git clone https://gitlab.esrf.fr/mirone/orange_shadok

Now we first need to install the dependencies. Install the dependencies

   cd ~/software/orange_shadok
   pip install -r requirements.txt

Now you can install the package ::

    pip install -e .

INSTALLATION OF THE XRStools

Download sources from gitlab

cd ~/software
git clone  https://gitlab.esrf.fr/mirone/XRStools

Install the tools . Mind that XRStools installs with python setup.py, not pip:

cd XRStools
git checkout alessandro   # or another branch, this tutorial is done with this branc
pip install  -r requirements.txt
python setup.py install  ## mind the python setup.py,  not  pip is used here (more practical for C compiling)

RUNNING THE DEMO

go to ~/software/orange_shadok/test

orange-canvas -l 4

And then load the workflow demo.ows
