**CO2MPAS** is backward-looking longitudinal-dynamics CO\ sub(`2`) and
fuel-consumption simulator for light-duty vehicles (cars and vans),
specially crafted to back-translate consumption figures from WLTP cycles
into NEDC ones.

It is an open-source project developed with Python-3.4,
using Anaconda & WinPython under Windows 7, Anaconda under MacOS, and
Linux's standard python environment.
The program runs as a *console command*.

History
=======
The *European Commission* is supporting the introduction of the *WLTP cycle*
for Light-duty vehicles developed at the *United Nations (UNECE)*
level, in the shortest possible time-frame. Its introduction requires
the adaptation of CO\ sub(`2`) certification and monitoring procedures set
by European regulations. European Commission's *Joint Research Centre* has been
assigned the development of this vehicle simulator to facilitate this
adaptation.



Quickstart
==========
.. Tip::
    **About console-commands:**

    - Console-commands beginning with ``$`` symbol are for the ``bash`` shell
      (UNIX).

    - Console-commands beginning with ``>`` symbol are for *Windows* ``cmd.exe``
      command-prompt.

    - You can adapt commands between the two shells with minor modifications
      (i.e. ``mkdir <--> md``, ``rm <--> del``).

    - You may download and install the *all-in-one* archive which contains
      both shells configured in a console supporting decent copy-paste and
      resizing capabilities (see ref:`all-in-one`_).


IF you have familiarity with v1 release AND IF you already have a full-blown
*python-3 environment* (i.e. *Linux* or the *all-in-one* archive) you can
immediately start working with the following *bash* commands; otherwise
follow the detailed instructions under sections ref:`install`_ and
ref:`usage`_.

.. code-block:: console

    ## Install co2mpas.
    ## NOTE: If behind proxy, specify additionally this option:
    ##    --proxy http://user:password@yourProxyUrl:yourProxyPort
    ##
    $ pip install co2mpas --extra-index http://pypi.co2mpas.io/simple/ --trusted-host pypi.co2mpas.io

    ## Where to store input and output files.
    ## In *Windows* cmd-prompt use `md` command instead.
    $ mkdir input output

    ## Create a template excel-file for inputs.
    $ co2mpas template input/vehicle_1.xlsx

    ###################################################
    ## Edit generated `./input/vehicle_1.xlsx` file. ##

    ## Run simulator.
    $ co2mpas -I input -O output

.. _install:

Install
=======
The installation procedure has 2-stages:

1. Install (or Upgrade) Python (2 choices under *Windows*).
2. Install CO2MPAS:
    a. Install (or Upgrade) executable.
    b. (optional) Install documents.
    c. (optional) Install sources.

On *Windows* you may alternatively install the *all-In-One* archive
instead of performing the above 2 steps separately.


.. _all-in-one:

*All-In-One* Installation under Windows
---------------------------------------
- Download **all-in-one archive** from
  http://files.co2mpas.io/.
  Ensure that you download the correct 32/64 architecture for your PC
  (the 64bit archive CANNOT run on 32bit PCs, but the opposite is possible).

- Use the original `"7z" extraxtor <http://portableapps.com/apps/utilities/7-zip_portable>`_,
  since "plain-zip" produces out-of-memory errors when expanding long
  directories.
  Prefer an **installation-folder without any spaces leading to it**.

- If you have already downloaded a previous version of the *all-in-one*
  archive, you may prefer to just upgrade CO2MPAS contained within.
  Follow the instructions in the "Upgrade" section, below.

- After installation, check that the version of CO2MPAS contained in the
  archive corresponds to the latest/the one described in these instructions.
  If not, follow the instructions in the "Upgrade" section, below.

- Visit the guidelines for its usage: doc(`allinone`)
  (also contained within the archive).


Python Installation
-------------------
If you already have a suitable python-3 installation with all scientific
packages updated to their latest versions, you may skip this 1st stage.

.. Note::
    **Installing Python under Windows:**

    The program requires CPython-3, and depends on *numpy*, *scipy*, *pandas*,
    *sklearn* and *matplotlib* packages, which depend on C-native backends
    and need a C-compiler to install from sources.

    In *Windows* it is strongly suggested **NOT to install the standard CPython
    distribution that comes up first(!) when you google for "python windows"**,
    unless you are an experienced python-developer, and you know how to
    hunt down pre-compiled dependencies from the *PyPi* repository and/or
    from the `Unofficial Windows Binaries for Python Extension Packages
    <http://www.lfd.uci.edu/~gohlke/pythonlibs/>`_.

    Therefore we suggest that you download one of the following two
    *scientific-python* distributions:

      #. `WinPython <https://winpython.github.io/>`_ **python-3** (prefer 64 bit)
      #. `Anaconda <http://continuum.io/downloads>`_ **python-3** (prefer 64 bit)



Install WinPython
~~~~~~~~~~~~~~~~~
The *WinPython* distribution is just a collection of the standard pre-compiled
binaries for *Windows* containing all the scientific packages, and much more.
It is not update-able, and has a quasi-regular release-cycle of 3 months.


1. Install the latest python-3 (preferably 64 bit) from https://winpython.github.io/.
   Prefer an **installation-folder without any spaces leading to it**.

2. Open the WinPython's command-prompt console, by locating the folder where
   you just installed it and run (double-click) the following file::

        <winpython-folder>\"WinPython Command Prompt.exe"


3. In the console-window check that you have the correct version of
   WinPython installed, and expect a similar response:

   .. code-block:: console

        > python --version
        Python 3.4.3

        REM Check your python is indeed where you installed it.
        > where python
        ....


4. Use this console and follow ref:`co2mpas-install`_ instructions, below.



Install Anaconda
~~~~~~~~~~~~~~~~
The *Anaconda* distribution is a non-standard Python environment that
for *Windows* containing all the scientific packages we need, and much more.
It is not update-able, and has a semi-regular release-cycle of 3 months.

1. Install Anaconda python 3.4 (preferably 64 bit) from http://continuum.io/downloads.
   Prefer an **installation-folder without any spaces leading to it**.

   .. Note::
        When asked by the installation wizard, ensure that *Anaconda* gets to be
        registered as the default python-environment for the user's account.

2. Open a *Windows* command-prompt console::

        "windows start button" --> `cmd.exe`

3. In the console-window check that you have the correct version of
   Anaconda-python installed, by typing:

   .. code-block:: console

        > python --version
        Python 3.4.3 :: Anaconda 2.3.0 (64-bit)

        REM Check your python is indeed where you installed it.
        > where python
        ....

4. Use this console and follow ref:`co2mpas-install`_ instructions, below.


.. _co2mpas-install:

CO2MPAS installation
--------------------
1. Install CO2MPAS executable internally into your python-environment with
   the following console-command:

   .. code-block:: console

        > pip install co2mpas --extra-index http://pypi.co2mpas.io/simple/ --trusted-host pypi.co2mpas.io
        Collecting co2mpas
        Downloading http://pypi.co2mpas.io/packages/co2mpas-...
        ...
        Installing collected packages: co2mpas
        Successfully installed co2mpas-1.0.3

   .. Note::
        **Installing Behind Firewall:**

        This previous step requires http-connectivity to Python's
        "standard" repository (https://pypi.python.org/) and to co2mpas-site.
        In case you are behind a **corporate proxy**, you may either:

        a) Append the following option to all ``pip`` commands, appropriatly
           adapted: ``--proxy http://user:password@yourProxyUrl:yourProxyPort``.

           For averting any security deliberations, JRC cryptographically signes
           all *final releases*, so that you or your IT staff may
           `validate their authenticity
           <https://www.davidfischer.name/2012/05/signing-and-verifying-python-packages-with-pgp/>`_
           and detect *man-in-the-middle* attacks, however impossible.

        b) Download all *wheel* packages from `co2mpas-site
           <http://files.co2mpas.io>`_ for the specific version you are
           interested in , and install them one by one:

           .. code-block:: console

                REM Download MANUALLY all `*.whl` files contained in release folder
                REM from co2mpas-site in some folder.
                > cd <folder-where-wheels_downloaded>
                > pip install *.whl


   .. Warning::
       If you cannot install CO2MPAS, re-run the command adding 2 *verbose*
       flags ``-vv``, copy-paste the console-output, and send it to JRC.


2. Check that when you run ``co2mpas``, the version executed is indeed the one
   installed above:

   .. code-block:: console

        > python -v --version
        co2mpas_version: 1.0.3
        co2mpas_path: d:\co2mpas_ALLINONE-XXbit-v1.0.3\Apps\WinPython\python-3.4.3\lib\site-packages\co2mpas
        python_path: D:\co2mpas_ALLINONE-XXbit-v1.0.3\WinPython\python-3.4.3
        python_version: 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:44:40) [MSC v.1600 XXX]


.. Warning::
    The above procedure installs the *latest* CO2MPAS, which
    *might be more up-to-date than the version described here!*

    In that case you can either:

    a) Visit the documents for version actually installed.
    b) "Pin" the exact version you wish to install with a ``pip`` command
       like this:

       .. code-block:: console

            > pip install co2mpas==1.0.3 ... # Other options, like above.



Install extras
~~~~~~~~~~~~~~
Internally CO2MPAS uses an algorithmic scheduler to execute model functions.
In order to visualize the *design-time models* and *run-time workflows*
you need to install the **Graphviz** visualization library  from:
http://www.graphviz.org/.

If you skip this step, the ``graphplot`` sub-command and the ``--plot-workflow``
option would both fail to run (see ref:`debug`_).



Upgrade CO2MPAS
~~~~~~~~~~~~~~~

1. Uninstall (see below) and re-install it.


Uninstall CO2MPAS
~~~~~~~~~~~~~~~~~
To uninstall CO2MPAS type the following command, and confirm it with ``y``:

.. code-block:: console

    > pip uninstall co2mpas
    Uninstalling co2mpas-<installed-version>
    ...
    Proceed (y/n)?


Re-run the command *again*, to make sure that no dangling installations are left
over; disregard any errors this time.



.. _usage:

Usage
=====
.. Note::
    The following commands are for the **bash console**, specifically tailored
    for the **all-in-one** archive.


First ensure that the latest version of CO2MPAS is properly installed, and that
its version match the version declared on this file.

The main entry for the simulator is the ``co2mpas`` console-command,
which **is not visible, but it is installed in your PATH.**
To get the syntax of the ``co2mpas`` console-command, open a console where
you have installed CO2MPAS (see ref:`install`_ above) and type:

.. code-block:: console

    $ co2mpas --help
    Predict NEDC CO2 emissions from WLTP cycles.

    Usage:
        co2mpas [simulate] [-v] [--predict-wltp] [--more-output] [--no-warn-gui] [--plot-workflow]
                           [-I <fpath>] [-O <fpath>]
        co2mpas demo       [-v] [-f] <folder>
        co2mpas template   [-v] [-f] <excel-file-path> ...
        co2mpas ipynb      [-v] [-f] <folder>
        co2mpas modelgraph [-v] [-l | <models> ...]
        co2mpas [-v] --version
        co2mpas --help

    -I <fpath>       Input folder or file, prompted with GUI if missing [default: ./input]
    -O <fpath>       Input folder or file, prompted with GUI if missing [default: ./output]
    -l, --list       List available models.
   dict-wltp   Whether to predict also WLTP values.
    --more-output    Output also per-vehicle output-files.
    --no-warn-gui    Does not pause batch-run to report inconsistencies.
    --plot-workflow  Open workflow-plot in browser, after run finished.
    -f, --force      Overwrite template/sample excel-file(s).
    -v, --verbose    Print more verbosely messages.

    * Items enclosed in `[]` are optional.


    Sub-commands:
        simulate    [default] Run simulation for all excel-files in input-folder (-I).
        demo        Generate demo input-files inside <folder>.
        template    Generate "empty" input-file at <excel-file-path>.
        ipynb       Generate IPython notebooks inside <folder>; view them with cmd:
                      ipython --notebook-dir=<folder>
        modelgraph  List all or plot available models.

    Examples:

        # Create sample-vehicles inside the `input` folder.
        # (the `input` folder must exist)
        co2mpas demo input

        # Run the sample-vehicles just created.
        # (the `output` folder must exist)
        co2mpas -I input -O output

        # Create an empty vehicle-file inside `input` folder.
        co2mpas template input/vehicle_1.xlsx

        # View a specific submodel on your browser.
        co2mpas modelgraph gear_box_calibration

The default sub-command (``simulate``) accepts either a single **input-excel-file**
or a folder with multiple input-files for each vehicle, and generates a
**summary-excel-file** aggregating the major result-values from these vehicles,
and (optionally) multiple **output-excel-files** for each vehicle run.


Running Samples
---------------
The simulator contains input-files for demo-vehicles that are a nice
starting point to try out.

1. Choose a folder where you will store the *input* and *output* files:

   .. code-block:: console

        ## Skip this if ``tutorial`` folder already exists.
        $ mkdir tutorial
        $ cd tutorial

        ## Skip also this if folders exist.
        $ mkdir input output

  .. Note::
    The input & output folders do not have to reside in the same parent,
    neither to have these names.
    It is only for demonstration purposes that we decided to group them both
    under a hypothetical ``some-folder``.

3. Create the demo vehicles inside the *input-folder* with the ``demo``
   sub-command:


   .. code-block:: console

        $ co2mpas demo input
        Creating DEMO INPUT file 'input\co2mpas_demo_1_full_data.xlsx'...
        Creating DEMO INPUT file 'input\co2mpas_demo_2_wltp_high_only.xlsx'...
        Creating DEMO INPUT file 'input\co2mpas_demo_3_wltp_low_only.xlsx'...
        Creating DEMO INPUT file 'input\co2mpas_demo_4_baseline_no_battery_currents - Copy.xlsx'...
        Creating DEMO INPUT file 'input\co2mpas_demo_5_baseline_no_gears.xlsx'...
        You may run DEMOS with:
            co2mpas simulate -I input

4. Run the simulator:

   .. code-block:: console

      $ co2mpas -I input -O output
      Processing 'input' --> 'output'...
      Processing: co2mpas_demo_1_full_data
      ...
      ...
      Done! [90.765501 sec]


6. Inspect the results:

   .. code-block:: console

      $ start output/*summary.xlsx       ## More summaries might exist in the folder from previous runs.
      $ start output                     ## View the folder with all files generated.


Output files
~~~~~~~~~~~~
Below is the structure of the output-files produced for each vehicle::

    ## Input and calibrated values for electrics.
    <timestamp>_precondition_WLTP_<inp-fname>.xls

    ## Input and calibrated values.
    <timestamp>_calibration_WLTP-H_<inp-fname>.xls

    ## Input and calibrated values.
    <timestamp>_calibration_WLTP-L_<inp-fname>.xls

    ## Input and predicted values.
    <timestamp>_prediction_NEDC_<inp-fname>.xls

    ## Major CO2 values from all vehicles in the batch-run.
    <timestamp>_summary.xls


Entering new vehicles
---------------------
You may modify the samples vehicles and run again the model.
But to be sure that your vehicle does not contain by accident any of
the sample-data, use the ``template`` sub-command to make an *empty* input
excel-file:


1. Decide the *input/output* folders.  Assuming we are still in the ``tutorial``
   folder and we wish to re-use the ``input/output`` folders from the example
   above, we may clear all their contents with this:

   .. code-block:: console

        $ rm -r ./input/* ./output/*        Replace `rm` with `del` in *Windows* (`cmd.exe`)


2. Create an empty vehicle template-file (eg. ``vehicle_1.xlsx``) inside
   the *input-folder* with the ``template`` sub-command:

   .. code-block:: console

        $ co2mpas template input/vehicle_1.xlsx  ## Note that here we specify the filename, not the folder!
        Creating TEMPLATE INPUT file 'input/vehicle_1.xlsx'...


3. Open the template excel-file to fill-in your vehicle data
   (and save it afterwards):

   .. code-block:: console

      $ start input/vehicle_1.xlsx        ## Opens the excel-file. Use `start` in *cmd.exe*.

   .. Tip::
       The generated file contains help descriptions to help you populate it
       with vehicle data.  For items where an array of values is required
       (i.e. gear-box ratios) you may reference different parts of
       the spreadsheet following the syntax of the `"xlref" mini-language
       <https://pandalone.readthedocs.org/en/latest/reference.html#module-pandalone.xleash>`_.

   You may repeat these last 2 steps if you want to add more vehicles in
   the *batch-run*.

4. Run the simulator.  Specify the single excel-file as input:

   .. code-block:: console

      $ co2mpas -I ./input/vehicle_1.xlsx -O output
      Processing './input/vehicle_1.xlsx' --> 'output'...
      Processing: vehicle_1
      ...
      Done! [12.938986 sec]

5. Assuming you do receive any error, you may now inspect the results:

   .. code-block:: console

      $ start output/*summary.xlsx       ## More summaries might open from previous runs.
      $ start output                     ## View all files generated (see below).


6. In the case of errors, or if the results are not satisfactory, repeat the
   above procedure from step 3 to modify the vehicle and re-run the model.
   See also ref:`debug`_, below.


Using IPython
-------------
You may enter the data for a single vehicle and run its simulation, plot its
results and experiment in your browser using `IPython <http://ipython.org/>`_.

The usage pattern is similar to "demos" but requires to have **ipython**
installed:

1. Ensure *ipython* with *notebook* "extra" is installed:

   .. Warning::
        This step requires too many libraries to provide as standalone files,
        so unless you have it already installed, you will need a proper
        *http-connectivity* to the standard python-repo.

   .. code-block:: console

        $ pip install ipython[notebook]
        Installing collected packages: ipython[notebook]
        ...
        Successfully installed ipython-x.x.x notebook-x.x.x


2. Then create the demo ipython-notebook(s) into some folder
   (i.e. assuming the same setup from above, ``tutorial/input``):

   .. code-block:: console

        $ pwd                     ## Check our current folder (``cd`` alone for Windows).
        .../tutorial

        $ co2mpas ipynb ./input

3. Start-up the server and open a browser page to run the vehicle-simulation:

   .. code-block:: console

        $ ipython notebook ./input

4. A new window should open to your default browser (AVOID IEXPLORER) listing
   the ``simVehicle.ipynb`` notebook (and all the demo xls-files).
   Click on the ``*.ippynb`` file to "load" the notebook in a new tab.

   The results are of a simulation run already pre-generated for this notebook
   but you may run it yourself again, by clicking the menu::

        "menu" --> `Cell` --> `Run All`

   And watch it as it re-calculates *cell* by cell.

5. You may edit the python code on the cells by selecting them and clicking
   ``Enter`` (the frame should become green), and then re-run them,
   with ``Ctrl + Enter``.

   Navigate your self around by taking the tutorial at::

        "menu" --> `Help` --> `User Interface Tour`

   And study the example code and diagrams.

6. When you have finished, return to the console and issue twice ``Ctrl + C``
   to shutdown the *ipython-server*.


.. _debug:

Debugging and investigating results
-----------------------------------

- Make sure that you have installed `graphviz`, and when running the simulation,
  append also the ``--plot-workflow`` option.

- Use the ``modelgraph`` sub-command to plot the offending model (or just
  out of curiosity).  For instance:

  .. code-block:: console

        $ co2mpas modelgraph gear_box_calibration

  ..  _static/GearModel.png
    :alt: Flow-diagram of the Gear-calibration model.
    :height: 240
