Installation

This time, the ALLINONE is distributed in two ways:, either as the usual AllInOne archive or as an Upgrade Pack:

1. AllInOne archive

The installations instructions for the AllInOne remain the same:

1. Download and extract the archive co2mpas_AIO-2.0.0.7z (direct download)
   attached at the top of this page (https://github.com/JRCSTU/CO2MPAS-TA/releases/tag/co2mpas-r2.0.0).

2. Optionally execute [ΑΙΟ]/INSTALL.vbs to add items into your Windows Start Menu;

3. Transfer from the old AIO:

   • the configurations,
   • your keys, and
   • optionally your dice-projects,

   according to the instructions at the CO₂MPAS wiki and the "key provisioning" material that have been distributed to all designated users .

2. UpgradePack

The UpgradePack(UP) can upgrade an existing AIO-1.7.3 so
you don't have to transfer your configurations, keys & projects.

ATTENTION: once upgraded, you cannot downgrade an AIO!
If you still want to run the old version of co2mpas, create a copy of your existing AIO and apply the UP on that clone.

To upgrade:

1. Download into the HOME folder of your existing AIO the script-file co2mpas_AIO_UpgradePack-2.0.0.sh (direct download)
   attached at the top of this page (https://github.com/JRCSTU/CO2MPAS-TA/releases/tag/co2mpas-r2.0.0).

2. Launch CO2MPAS console and open a bash ("brown") tab: File --> New Tab --> bash, or simply press [Ctrl+F2].

3. Execute the downloaded script with this command:

   ./co2mpas_AIO_UpgradePack-2.0.0.sh

4. Wait ~20 minutes to upgrade..

In both cases, validate the installation with these 2 commands:

co2mpas -vV
co2dice config paths

Important Changes since 1.7.4 release

We kindly invite you to read the Release Notes and Known Limitations in detail - highlights are listed below.

• CHANGE: Changed vehicle_family_id format (but old format is still supported):

    OLD: FT-TA-WMI-yyyy-nnnn
    NEW: FT-nnnnnnnnnnnnnnn-WMI-x
  

• CHANGE: The co2mpas python package is now splitted into 4 python packages: co2sim, co2dice, co2gui, co2mpas. In practice this means that you can still receive bug-fixes and new features for the DICE or the GUI, while keeping the simulation-model (co2sim) intact. For instance, to update all co2mpas packages now you would type this command: pip install -U co2sim co2dice co2gui co2mpas.

Model:

• feat(core): Improve calibration performances 60%.
• feat(manual): Add a manual prediction model according GTR.
• feat(gearbox): Add utility to design gearbox ratios if they cannot be identified
  based on maximum_velocity and maximum_vehicle_laden_mass.
  This is not affecting the TA mode.
• fix(vehicle): Default n_dyno_axes as function of
  n_wheel_drive for wltp (4wd-->2d, 2wd-->1d).
  • If nothing is specified, default values now are:

    n_dyno_axes = 1
    n_wheel_drive = 2
    

  • If only n_wheel_drive is selected, then the default for n_dyno_axes is calculated as function of n_wheel_drive for wltp (4wd-->2d, 2wd-->1d).
  • If only n_dyno_axes is selected, then n_wheel_drive defaults to 2.
• fix(vva): Remove _check_vva; engine_has_variable_valve_actuation = True and ignition_type = compression' is permitted.
• fix(start_stop): Disable start_stop_activation_time when has_start_stop == True.
• fix(ta): Disable function define_idle_fuel_consumption_model
  and default_start_stop_activation_time.
• fix(electrics): Improve calculation of state of charges.
• fix(at): Correct correct_gear_full_load method using the best gear
  instead of the minimum when there is not sufficient power.

Known Limitations for Model

• Reproducibility has been greatly enhanced, with quasi-identical results
  in different platforms (linux/Windows).

IO Data

• BREAK: Bumped input-file version from 2.2.7 --> 2.3.0. And
  improved file-version comparison (Semantic Versioning)
• FEAT: Input-template provide separate H/L fields for both ki multiplicative and Ki additive parameters.
• FEAT: Add additional sheets for meta data (aka extra data):.
  As for September 2018, the user can voluntarily add data related to the all WLTP tests held for
  a specific Interpolation Family ID. Since this addition is optional, the sheets are colored orange.
• FEAT(co2_emissions): Add engine_n_cylinders as input value and a TA parameter.
• CHANGE: Rename ki_factor to ki_multiplicative and add
  ki_additive value.
• change: The parameter "Vehicle Family ID" has been renamed to "Interpolation Family ID" to some places.
• feat(ta): Running CO2MPAS in TA mode produces an extra .tar file to be used in the feature version of DICE.

DICE

• FEAT: Added a new "Stamp" button on the GUI, which stamps with WebStamper
  in the background in one step; internally the button invokes the new co2dice dicer command
  which function as a sequencer for dicing new or existing projects
  through WebStamper, in a single run:

  co2dice dicer -i co2mpas_demo-1.xlsx -o O/20180812_213917-co2mpas_demo-1.xlsx

  NOTE that the GUI-button (and the underlying co2dice dicer command)
  work only with pre-production WebStamper.
  The URL of the server will be distributed with emails, not to expose it to DOS attacks.

• FEAT: The commands co2dice dicer|init|append|report|recv|parse and
  co2dice tstamp wstamp, support one or more --write-file <path>/-W options,
  to and every time they run, they can append or overwrite into all given <path>
  these 3 items as they are generated/received:

  1. :term:Dice report;
  2. :term:Stamp (or any errors received from :term:WebStamper;
  3. :term:Decision.

  By default, one <path> is always ~/.co2dice/reports.txt, so this becomes
  the de-facto "keeper" of all reports exchanged.

  The pre-stamper now supports uploading files (instead of copy-pasting text).

• drop: deprecate all email-stamper commands; few new enhancements were applied
  on them.

Known Limitations for dice

• Fixed known limitation of 1.7.3 (:gh:448) of importing stamps from an older
  duplicate dice.
• It is not possible to --recertify from nedc state
  (when mored files have been appended after stamping).
• There is still no high level command to view Stamps (see low-level command
  in the old known limitation item).
  But :term:stamp\s received are now save in :file:~/.co2dice/reports.txt
  (along with :term:dice\s and :term:decision\s).
• The decision-number generated still never includes the numbers 10, 20, …90.
• All previous known limitations regarding :term:mail-stamper still apply.
  But these commands are now deprecated.

Various

• FIX: Support pip >= 10+ (fixes #26).
• Pinned versions of dependencies affecting the accuracy of the
  calculations, to achieve stronger reproducibility; these dependent
  libraries are shipped with AIO (see 427).
• Accurate versioning of project with polyvers utility.
• feat: provide a docker script, ensuring correct numpy-base+MKL
  installed in conda requirements.

9 Aug 2018: backported 1.9.x fixes to facilitate re-installations

-((announcement refers to end-of-line co2mpas-1.7.x - no need to upgrade))-

---

Changes since v1.7.4.post3

Pinned co2mpas dependencies to improve reproducibility...

when installing it in a newer AIO (forthmocing v1.9.x):
ATTENTION:
upgrading/downgrading co2mpas between major-releases renders the AIO unsuitable for "official" purposes - it can be used though for engineering studies.

Transitive dependencies are now served from 2 places:

• file setup.py: contains bounded dependency versions to ensure proper
  functioning, but not reproducibility.

  These bounded versions apply when installing from PyPi with command
  pip instal co2mpas==1.7.4.post2; then :command:pip will install
  dependencies with as few as possible transitive re-installations.

• file requirements/exe.pip & file requirements/install_conda_reqs.sh:
  contain the pinned versions of all calculation-important dependent libraries
  (see :gh:463).

  You need to get the sources (e.g. git-clone the repo) to access this file,
  and then run the command pip install -r <git-repo>/requirements/exe.pip.

Other fixes:

• Support pip >= 10+ (fixes :ghp:26).
• Fix conflicting dill requirement.
• Fix piping dice-commands to stdout.
• No model changes.

15 Nov 2017: "Toketos" enhancements for WebStamper

-((10 Aug 2018: ex-post announcement of this release for historical purposes))-

---

Changes

• feat(dice, :gh:447): Allow skipping tsend -n command to facilitate
  :term:WebStamper, and transition from tagged --> sample / nosample.

• fix(co2p, :gh:448): tparse checks stamp is on last-tag (unless forced).
  Was a "Known limitation" of previous versions.

16 Oct 2017: --recertify added

-((10 Aug 2018: ex-post announcement of this release for historical purposes))-

---

Changes since 1.7.3:

• feat(co2p): The new option --recertify to co2dice project append allows to extend
  certification files for some vehile-family with new ones

  Note:
  The old declaration-files are ALWAYS retained in the history of "re-certified"
  projects. You may control whether they old files will be also visible in the
  new Dice-report or not.

  For the new dice-report to contain ALL files (and in in alphabetical-order),
  use different file names - otherwise, the old-files will be overwritten.
  In the later case, the old files will be visible only to those having access
  to the whole project, such as the TAAs after receiving the project's exported
  archive.

• fix(co2p): co2dice project commands were raising NPE exception when iterating
  existing dice tags, e.g. co2dice project export . to export only the current
  project raised::

  AttributeError: 'NoneType' object has no attribute 'startswith'
  

• fix(tstamp): co2dice tstamp were raising NPE exceptions when -force used on
  invalid signatures.

16-Aug-2017: "T-REA" Release

--((this page has the AIO- for 1.7.x: co2mpas_AIO-1.7.3.7z ))-

• CO₂MPAS-model changes

• CO₂DICE connectivity & usability enhancements

• (replaces the retracted AIO-1.6.1 "T-bone" release)

• This release takes place after the enactment of (EU) 2017/1151 "correlation" legislation on 27th of July,
  and will become the official version by the 1st of September 2017, and obligatory after the 1st of November 2017.
• This release can be used for "Dicing" as of 27 July 2017, as explained in this DG Clima document on the matter:
  https://ec.europa.eu/clima/sites/clima/files/transport/vehicles/cars/docs/correlation_implementation_information_en.pdf

Please report any bugs or questions preferably in the GIThub platform, and for confidential issues,
use the dev-team's CO₂MPAS mailbox (JRC-CO2MPAS@ec.europa.eu).

Installation

The installations instructions for the AllInOne remain the same:

• Download and extract the archive at the bottom of this page:
  https://github.com/JRCSTU/CO2MPAS-TA/releases/tag/v1.7.3
• execute [ΑΙΟ]/install.vbs;
• read the instructions contained in the [AIO]/README.txt.

Important Changes

We kindly invite you to read the Release Notes and Known Limitations in detail - highlights are listed below.

CO₂MPAS-model

• Speed-up prediction phase.
• Resolved instability problems(small changes in bag input-values were leading
  to disproportional changes in NEDC prediction).
• Thermal model: Add a filter to remove invalid temperature derivatives
  (i.e. abs(DT) >= 0.7) during the cold phase.
• Clutch model: Some extra RPM (peaks) have been verified before the engine’s stops.
  This problem has been resolved filtering out clutch_delta > 0 when acc < 0 and
  adding a features selection in the calibration of the model.
• Engine model: The auxiliaries_torque_losses are function of engine_capacity.
• Consumption/emissions model:
  • Implement a fuzzy rescaling function to improve the stability of the model when rounding
    the WLTP bag values.
  • bugfix: in tau_function when a hot cycle is given.
  • Set co2_params limits to avoid unfeasible results.
  • Rewrite of calibrate_co2_params function to reuse the identified_co2_params on each pertubation.
  • Set gearbox, torque, and power losses parameters to optimum values based on fleet data.
• Known Limitations:
  • Minor differeces have been observed occasionally when model runs on different computers
    (in the order of the 10th decimal digit).

CO₂DICE

• Introduce a 2nd type of report, "decision-report", containing HASH-#2 of the regulation, that needs to be communicated to the TAA (HASH-#1 is contained in the dice-report).
  The new report gets produced on the last step of the dicing by the project trecv/tparse sub-commands;
  you may review it later by using project report sub-command.
  You may distinguish the new by its sequence-number which it is usually /1 (dice-report is /0), like this:

   object 4b444d951ecb56c462cb7d3bf1b2529fb642c7ea
   type commit
   tag dices/IP-10-AAA-2017-4321/1
  

  A TAA can unequivocally identify a certification-process if the TS sends the following (hand-edited) text:

   dices/IP-10-AAA-2017-4321/1: 4b444d951ecb56c462cb7d3bf1b2529fb642c7ea
  

  (edit: 4-Oct-2017)

• For other changes, please read the guidelines provided on how to use the Dice;

• For the list of changes and new features, read the Release Notes: https://co2mpas.io/changes.html#the-dice

• Known Limitations:

  • Microsoft Outlook Servers are known to corrupt the dice-emails; depending
    on the version and the configurations, most of the times they can be fixed.
    If not, as a last resort, another email-account may be used.

    A permanent solution to the problem will be provided when the
    the Exchange Web Services (EWS) protocol is implemented in co2mpas.

  • On Yahoo servers, the TstampReceiver.subject_prefix param must not
    contain any brackets ([]). The are included by default, so you have to
    modify that in your configs.

  • Using GMail accounts to send Dice may not(!) receive the reply-back "Proof of
    Posting" reply (or it may delay up to days). Please perform tests to discover that,
    and use another email-provided if that's the case.

    Additionally, Google's security provisions for some countries may be too
    strict to allow SMTP/IMAP access. In all cases, you need to enable allow
    less secure apps to
    access your account.

  • Some combinations of outbound & inbound accounts for dice reports and timsestamps
    may not work due to DMARC restrictions.
    JRC will offer more alternative "paths" for running Dices. All major providers
    (Google, Yahoo, Microsoft) will not allow your dice-report to be stamped and forwarded
    to TstampSender.stamp_recipients other than the Comission; you may (or may not)
    receive "bounce" emails explaining that.

  • There is no high level command to view the stamp for some project;
    Assuming your project is in sample or nosample state, use this cmd:

    cat %HOME%/.co2dice/repo/tstamp.txt
    

IO & Data:

• bugfix: excel validation formulas on input-template & demos did not accept vehicle-family-id with single-digit TA-ids.
• output template:: add co2_rescaling_scores and cycle scores .
• summary file: add co2_rescaling_scores and model scores.
• Disable input-file caching by default (renamed option --override-cache --> --use-cache.
• Datasync:
  • bugfix: stop producing 0 values in the first and/or in the last cells.
    This has been fixed extending the given signal with the first and last values.
  • bugfix: remove buggy interpolation methods.
• Known Limitations:
  The co2mpas modelgraph command cannot plot flow-diagrams if Internet Explorer (IE)
  is the default browser. Copy the URL and paste it in another browser to visualize the diagrams.

GUI & console

• feature: co2gui command does not block, and stores logs in temporary-file. It launches this file in a text-editor in case of failures.
• feature: Set initial window-size for GUI & console not larger than a low-end laptop.;
  remember them afterwards (stored in persistent JSON file).

All-in-One

• Detect 32bit Windows early, and notify user with an error-popup.
• Possible to extract AIO-archive into a path with SPACES (but not recommended).
• Switched POSIX layer from Cygwin –> MSYS2, for having better support in Windows paths, and
  using the pacman package manager.
  Archive's size increased from ~350MB –> ~450MB.

• Implement a fuzzy rescaling function to improve the stability of the model when rounding the WLTP bag values.

• bugfix: in tau_function when a hot cycle is given.

• Set co2_params limits to avoid unfeasible results.

• Rewrite of calibrate_co2_params function.

• Use the identified_co2_params as initial guess of the calibrate_co2_params. Update CO₂ optimizer enabling all steps in the identification and disabling the first two steps in the calibration. Optimize the parameters that define the gearbox, torque, and power losses.

IO & Data:

• bugfix: excel validation formulas on input-template & demos did not accept vehicle-family-id with single-digit TA-ids.

• Add cycle scores to output template.

• Add model scores to summary file.

• Report co2_rescaling_scores to the output file and the summary file.

• Disable input-file caching by default (renamed option --override-cache --> use-cache

• Known Limitations: the CO₂MPAS modelgraph command cannot plot flow-diagrams if Internet Explorer (IE) is the default browser. Copy the URL and paste it in another browser to visualize the diagrams.

GUI

• feature: co2gui command does not block, and stores logs in temporary-file. It launches this file in a text-editor in case of failures.

• feature: remember position and size of the window between launches (stored in persistent JSON file).

All-in-One

• Detect 32bit Windows early, and notify user with an error-popup.

• Possible to extract archive into path with SPACES (not recommended though).

• Switched from Cygwin–>MSYS2 for the POSIX layer, for better support in Windows paths, and package manager update manager. Size increased from ~350MB –> ~530MB.

• Use [AIO] to refer to the ALLINONE base-folder in the documentation.

The Dice

Please read carefully and pay particular attention to the guidelines provided on how to set up and use The Dice. function.

• Dice commands won’t start without the configuration files; remember to transfer your configurations from your old AIO or request them to the JRC if it is your first use.

• enhance handling of email encodings on send and receive

• add --subject and --on options for search criteria on the tstamp recv and project trecv subcommands.

• bugfix: BCC-addresses were treated as CCs; --raw output was corrupted.

• new feature: possible to modify selectively logging output with ~/logconf.yaml file; Having more detailed logs generally improve error handling.

• Known Limitations
  Microsoft Outlook Servers are known to corrupt the dice-emails; depending on the version and the configurations, most of the times they can be fixed. If not, as a last resort, another email-account may be used, either to receive the tstamps (added in the tstamp_recipient param), or to send the dice-email in the first place.

A permanent solution to the problem will be provided when the the Exchange Web Services (EWS) protocol is implemented in CO₂MPAS.

On Yahoo servers, the TstampReceiver.subject_prefix param must not contain any brackets ([]).

Using GMail accounts to sent Dice may not(!) receive the reply-back “Proof of Posting” reply (or it may delay up to 4 hours). It is recommended to have a 2nd email address in the tstamp_recipients to receive the dice-tstamp email within minutes.

Additionally, Google’s security provisions for some countries may be too strict to allow SMTP/IMAP. In all cases, you need to enable allow less secure apps to access your account.

Datasync

• Datasync was producing 0 values in the first and/or in the last cells. This has been fixed extending the given signal with the first and last values.

• bugfix: remove buggy interpolation methods.
