Step 1 - Create a virtual env (recommended) '''''''''''''''''''''''''''''''''''''''''''

It is recommended to create a python virtual environment to run the workflow tool. Virtual environment might avoid some conflict between python packages. But you can also install it on your 'current' python environment and move to step 1.

.. code-block:: bash

virtualenv --python=python3 --system-site-packages myvirtualenv

Then activate the virtual environment

.. code-block:: bash

source myvirtualenv/bin/activate

First update pip and setuptools to avoid some potential errors

.. code-block:: bash

pip install --upgrade pip pip install setuptools --upgrade

.. note:: To quit the virtual environment

.. code-block:: bash


Step 2 - tomwer (madatory) ''''''''''''''''''''''''''

To install it with all 'features':

.. code-block:: bash

pip install tomwer[full]

alternatively you can install the master branch from

.. code-block:: bash

pip install git+[full]

Step 3 - update orange-canvas-core and orange-widget-base (recommended) '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

To access 'processing' wheels you might want to install forks of update orange-canvas-core and orange-widget-base

.. code-block:: bash

pip install --no-deps --upgrade
pip install --no-deps --upgrade

Launching applications ::::::::::::::::::::::

After the installation tomwer is embedding several applications.

Those applications can be launched by calling:

.. note:: You can access each application help using ``

.. code-block:: bash

tomwer canvas - orange canvas '''''''''''''''''''''''''''''

You can launch the canvas to create workflows from the different 'bricks'

.. code-block:: bash

tomwer canvas

.. note:: if your installed a virtual environment do not forget to active it :

.. code-block:: bash

   source myvirtualenv/bin/activate

Documentation :::::::::::::

cd doc make html

The documentation is build in doc/build/html and the entry point is index.html
