QtWidgets

[johansoderkvist]

I am not able to get the latest pyncview-git (https://github.com/BoldingBruggeman/pyncview) work together with the latest GOTM/code/gui (https://github.com/gotm-model/code)

For example:
python multiplot.py -s INFILE –e VARIABLE
gives: “cannot import name QtWidgets”
The error message is from multiplot.py
“ def plot(self,startmessageloop=True):
gui = self.output is None

    if gui:
        # We have to show figure in GUI.

        # Import PyQt libraries if not doen already.
        global QtWidgets
        if QtWidgets is None:
            from xmlstore.qt_compat import QtWidgets

“

To me, it seems like that module QtWidgets does not exist in:
GOTM/gotm-code/gui.py/xmlstore/qt_compat.py

Required paths are defined as export
GOTMDIR=HOME/GOTM/gotm-code
export PYTHONPATH=HOME/GOTM/gotm-code/gui.py

In multiplot.py, I have tried to shift from PyQt4 to PyQt5 and use
from PyQt5 import QtWidgets
instead, but since the xmlplot-dir use PyQt4, it is not a possible way forward

---

I have also tried to import the module in an ipython-environment:
ipython: from xmlstore.qt_compat import QtWidgets
In [1]: from xmlstore.qt_compat import QtWidgets
ImportError Traceback (most recent call last)
in ()
----> 1 from xmlstore.qt_compat import QtWidgets

ImportError: cannot import name QtWidgets

In [2]: import xmlstore.qt_compat

---

Thus, it is possible to import qt_compat but not the QtQidgets

It seems like older version of the pyncview-packages does not use QtWidgets.
In my older version of multiplot.py (def plot) use PyQt4-package instead:
“ global QtGui
from PyQt4 import QtGui”

---

Do you have any solution to get the pyncview package up and running?

Hi Johan pyncview/multiplot: Best is to install via pip - as described here: https://github.com/BoldingBruggeman/pyncview It seems you run a very old version of GOTM - you should update. gotmgui: If on Windows you'll also have to install the wheel from: https://github.com/gotm-model/code/releases If on Linux you'll have to compile your delf - use the CMake method.

Dear Karsten

Thank you for the tips. You are right about GOTM-version (I do not know how I mangaged to clone an old version though).
I have now downloaded and installed GOTM on linux as stated on: http://gotm.net/software/linux/
I have installed pyncview, xmlplot and xmlstore with pip.
QtWidget-problem is gone! Thanks!

Still, I run in to problems, a bit technichal though:

1. multiplot.py:
   multiplot.py -s INFILE -e VARIABLE
   “type object got multiple values for keyword argument 'markersize'”
   The error occur in
   HOME/.local/lib/python2.7/site-packages/xmlplot/plot.py
   axes.grid(True,**lineargs) # that is line 1999

where lineargs is defined as:
lineargs = getLineProperties(gridnode['LineProperties'])
Values of lineargs are:
{'color': (0.6901960784313725, 0.6901960784313725, 0.6901960784313725), 'markersize': 6.0, 'markeredgewidth': 0.5, 'markeredgecolor': (0.0, 0.0, 0.0), 'marker': u'', 'markerfacecolor': (0.6901960784313725, 0.6901960784313725, 0.6901960784313725), 'linewidth': 0.8, 'linestyle': u'-'}

thus "'markersize': 6.0, " seems to me be a very OK value., I do not understand why multiplot-py-command gives
“type object got multiple values for keyword argument 'markersize'”

Replacing
axes.grid(True,**lineargs)
with
axes.grid(True)
results in a nice image.

2. pyncview.py
   I can view image using pyncview. However zooming gives errors:

File "HOME/.local/lib/python2.7/site-packages/xmlplot/gui_qt4.py", line 360, in mouse_move
lastx, lasty, a, ind, lim, trans= self._xypress[0]
ValueError: need more than 5 values to unpack

So, something is missing in the object _xypress[0]
print self._xypress[0] (gives)
(174, 143.0, <matplotlib.axes._subplots.AxesSubplot object at 0x7f8f2c9d0210>, 0, (735964.0, 736329.9930555555, -0.4382813550207892, 2.5572712728477165))

In the old environment which works fine (same nc-file but not exact same zooming area) the print statement for self._xypress[0]) is:
"
(191, 386.0, <matplotlib.axes.AxesSubplot object at 0x3671bd0>, 0, Bbox(array([[ 7.35964000e+05, -5.00000000e-01],
[ 7.36329993e+05, 2.50000000e+00]])), Affine2D(array([[ 1.58814489e+00, 0.00000000e+00, -1.16872371e+06],
[ 0.00000000e+00, 2.00000000e+02, 1.75000000e+02],
[ 0.00000000e+00, 0.00000000e+00, 1.00000000e+00]])))

I hope that this information will be sufficient for you to pinpoint what is going on, and guide me to the next step!

Best regards
Johan

1: I'm afraid pyncview is only compatible with matplotlib up to 2.1.2 (not 2.2.2) pip2 install matplotlib==2.1.2 2: maybe same a 1 I don't understand why you have to write pyncview.py - it should have been installed into your path (the same folder as pip is in (*)) as pyncview - try 'type pyncview' if you have specified --user to pip remember to add ~/.local/bin to your path Den fre. 29. jun. 2018 kl. 14.31 skrev johansoderkvist < notifications@github.com>:

[johansoderkvist]

current version of matplotlib is 2.1.1, so that should not be a problem

Thanks for tip on pyncview

[bolding]

the tips for pyncview is also valid for multiplot - i.e. don't use multiplot.py - just multiplot and be sure to have the latest versions Den man. 2. jul. 2018 kl. 10.21 skrev johansoderkvist < notifications@github.com>:

I have downloaded and installed GOTM and pyncview.
matplotlib version =2.1.1

Still, not able to use multiplot:
python multiplot.py -s $INFILE -e VARIABLE
type object got multiple values for keyword argument 'markersize'

pyncview works fine, until I try to zoom or choosing specific coordinate (thus not 2D-plot)
Get similar error message, plus some error messages from directorys:
lib/python2.7/site-packages/xmlplot
lib/python2.7/site-packages/matplotlib/axis.py
