kdavies4 / modelicares Goto Github PK

Hi Kevin, (or whoever who read it)

I am trying to use modelicares in Jython (using easy_install, pip, ...) and I am getting this error:
ImportError: No module named py3k
(Installation in Python works fine!)
Do you know what is this py3k? Any experience about this issue?

Cheers!

@kdavies4 When I try the new merged version for simulations I get the following importerror:

Hello again!

I am having this error when importing SimRes

I am reading in "the web" that this issue might come from the re.compile() function. I guess you did not face this issue with the natu library. Any idea?

Cheers!

Carry-over from discussion in #26.

Do this with version 1.0, and start with a fresh repository?

Kevin, are you still using ModelicaRes often? I keep getting error messages with respect to natu :) If I want to translate the SimRes object to a dataFrame I get the following error:

I was just starting to use Modelica res however it seems that something does not quite work as it should:

In [11]:
from modelicares import SimRes
sim = SimRes('test.mat')
sim.find('ramp.y')
---------------------------------------------------------------------------

When trying to import SimRes I receive the following error.

In [1]: from modelicares import SimRes

SyntaxError: invalid syntax

Is there any way to fix this?

That way, can use doctest on it.

When multiple Sankey diagrams are generated at successive times in a simulation, the labels are appended. I need to submit a fix to the Sankey class of matplotlib. After it is accepted, remove the temporary change to 00-make-gh-pages.sh in the gh-pages branch.

Include this as an example in the tutorial.

Base this functionality on SimRes.names().

Consider using hierarchical column headings to reflect the structure of a Modelica model.

See astropy issue #2662.

There are multiple imports of matplolib.cbook.iterable (1, 2), however, this object is deprecated with maplotlib from version v3.1.0 (source).
This has already causing import errors.

An eassiest fix would be specifying matplotlib's version <3.1.0 in setup.py. In my case v3.0.0 worked.

When trying to export simulation data to a dataFrame pandas raises a KeyError.
The problem is that Dymola does not store the units into the *.mat-file when using Dymola functions like "writeTrajectory" or "Export Results".
It would be great if the function's return line could be updated to a more dynamic one, like:
return DataFrame(data).set_index('Time / '+self['Time'].unit)
This way one could use to_pandas() for modified simulation data.
Of course it would also be possible to change the data entry 'Time / ' to 'Time / s'.

It would be nice to see a more recent PyPI package.

Use PyFMI; see http://www.os.is/gogn/Skyrslur/OS-2012/OS-2012-06/OS-2012-06-03.pdf and http://nbviewer.ipython.org/gist/saroele/e6f176ac0ff391e8982a

Hi Kevin,

we're trying to set up MPC (model predictive control) with Modelica, and we need a continue-run framework. We can implement it with dymosim.exe or pyfmi, and we're happy to see that you have implemented this functionality. However, when we install mdoelica res with pip, the following doesn't work::

from modelicares.exps.simulators import dymosim

Any idea why not? And is it possible to do continue-simulations with pyfmi too?
Thanks,
Roel

Implement coveralls (see https://pypi.python.org/pypi/coveralls/0.4.2 and https://github.com/z4r/python-coveralls).

The following doc files link to _images which is not available.

simres.html

Dear Kevin,

Thank you for this nice project. Unfortunately I cannot use your software directly. The files 00-reindent.py and 00-tabnanny.py from the folder modelicares are symbolic links and I had to delete them in order to run the installation routine successfully.

Please check if these files are necessary and consider removing the symlinks or add the real files.

Thanks again,
Jorrit

The SimResList class does an excellent job of plotting simulation results of different simulations with the same start and stop time.

For continued simulations, it is unnecessary to divide the plot in different segments and give each segment a new name and color. For example:

I see two solutions:

• Adjust the plot() method to take this into account
• Create a new method (e.g. merge()) which merges the different simulation results in a new single result file

QT is used more widely, and it still seems to be difficult to get wx running with Python 3.

The line

import modelicares # Only to read the version number

Is a problem because this, by itself, tries to load a bunch of dependencies.

There are two ways to approach this:

1. Add the control package to the path during setup.py
2. Skip the import and provide the version number some other way.

If you do 1) there are lots of dependencies. Some are listed in the setup.py file (matplotlib, wx and numpy). Of these, wx is not the correct name for the extension you want. You want wxPython (which installs a package named wx, but is not the same as the PyPI listing for wx). But scipy is also a dependency even though it is not listed. The big problem here is that the mechanisms in setup.py don't kick in to load all these things. In other words, since modelicares is imported into setup.py, all the dependencies have to be installed in advance. On the other hand, if the import wasn't there and pip was used to install modelicares from PyPI, all the dependencies could actually be loaded automatically. Even if you load all of those dependencies, you still have the problem that the control package really needs to be installed first (because the external/control/src directory name doesn't match the package name). After all of this, I eventually gave up on this approach.

Taking approach 2 (which simply means commenting out the import line and substituting the version number ("0.8.1", in my case) into the setup.py script worked perfectly and modelicares installed without issue. Of course, this doesn't address the dependency issue (since a local install doesn't pull in all the dependencies). The issue with the dependencies (that wx should be wxPython that scipy is missing) are not addressed. Also, the control package still needs to be installed manually in that case.

One word of advice...the best way to test for these kinds of issues is to use virtualenv to create a pristine "install". These things come out of the woodwork in such cases.

There's two syntax errors in the sources.

1. In modelicares/simres.py, line 1723 and
2. In modelicares/_io/dymola.py line 131

substitute '<>' by '!='.

Run TODO.sh for a current listing.

The simulator.run() method should be able to set start and stop times for the simulation. This can be done by changing their respective values in the corresponding dsin.txt if we extend the write_params() method. For example:

import modelicares.exps.write_params as write_params
write_params({
  'StartTime': 0,
  'StopTime': 1000
}

I'm no expert in these file manipulations so could you @kdavies4 have a look at how to efficiently implement this?

Getting this error for .mat files generated by Dymola 2014 FD01.

This is issue is probably related to scipy/scipy@ecfae8b

I think the encoding should be 'latin-1' instead of 'ascii'

Hi,

I started working with ModelicaRes today. I was exploring the options but I'm stuck at the following.

I'd like to use the subplot command from matplotlib. Intuitively I tried:

sim = SimRes(arguments)
sim.add_subplot(2,1,1)    //from http://matplotlib.org/examples/animation/subplots.html
sim.plot(title="Title", ynames1=  ... etc)

but this does not seem to work. I can't seem to find an example in the documentation either. How can I approach this?

Thank you!

Currently returns NotImplementedError

Hi!
I am using this class, in modelicares.exps.simulators file, and... the script seems to be written fine, but I do not see how the class executes the .mos file. Its run method seems only to write commands into the .mos file, but how the .mos file is executed?
Cheers!

This may require using Qt instead of WX (Issue #11).

Consider merging this project with those listed in the "see also" section of the README.
- Support FMI (see PyFMI and pySimulator).
- Improve the GUI (pySimulator).
- Model testing (BuildingsPy).

Use the displayUnit by default but allow custom override in SimRes.get_values(), SimRes.get_IV(), etc.

Ideas for implementation:

• Replace the function f argument to SimRes.get_values(), etc. with a unit argument:
  • If default (None), then use displayUnit.
  • Accept string in Modelica notation (e.g., "m/s2"). The units may contain SI prefixes.
  • Accept values (e.g., m/s**2) where the values are available from a submodule (modelicares.units).
  • Accept functions (e.g., degC, dB), also from a submodule.
  • Build the units into the transformation from the data space to the axis space of matplotlib?
• Allow configuration of default units (via config file or code).
• Order of precedence: unit argument, default units, displayUnit attribute, unit attribute
• Also include constants in the units submodule (e.g., c/(m/s) should return 299792458).
• Each unit is a class that contains a dimension as well as a value. Use the dimension for dimension checking.
• List available units and constants in the documentation of modelicares.units.
