Additional info (worksheets, data, screenshots, ...)

Original issue was in wrong repository: biolab/orange2#46

This is probably the same problem as: https://stackoverflow.com/questions/34629635/orange-canvas-does-not-show-any-icon/ but manifested on Linux.

Are you using Anaconda provided PyQt4? If so are you running anaconda python in the root or a newly created conda environment?

Can you please run the following in bash shell with the correct python on $PATH

python - <<EOF
import os
import PyQt4
from PyQt4.QtGui import QImageReader, QApplication
print("PyQt4 installed in", os.path.dirname(PyQt4.__file__))
print("Qt4 library paths", QApplication.libraryPaths())
print([bytes(f).decode("ascii") for f in QImageReader.supportedImageFormats()])
EOF

[brylie]

>>> print("PyQt4 installed in", os.path.dirname(PyQt4.__file__))
PyQt4 installed in /home/brylie/anaconda3/lib/python3.5/site-packages/PyQt4
>>> print("Qt4 library paths", QApplication.libraryPaths())
Qt4 library paths []
>>> print([bytes(f).decode("ascii") for f in QImageReader.supportedImageFormats()])
['bmp', 'pbm', 'pgm', 'png', 'ppm', 'xbm', 'xpm']

[brylie]

I installed Anaconda as a normal user in my home directory.

[brylie]

There is an upstream issue related to the missing SVG format:

• PyQt missing SVG, JPG, TIFF and other support in QImageReader

[brylie]

I added a note to the upstream issue.

[ajdapretnar]

I had people reporting the same issue for OSX (with Anaconda). Works well on Windows.

[brylie]

I looked under the anaconda folder in my home directory. I found the following:

• ~/anaconda3/lib/qt4/plugins/iconengines
  • libqsvgicon.so
• ~/anaconda3/lib/qt4/plugins/imageformats
  • libqgif.so
  • libqjpeg.so
  • libqsvg.so
  • libqtiff.so
  • libqico.so
  • libqmng.so
  • libqtga.so

[brylie]

It seems like the SVG libraries are included as imageformats and iconengines. Is there another folder I should check?

[astaric]

Whan command do you use to run orange?

python -m Orange.canvas?

If so, please check that there is a qt.conf file in the folder with the python executable and that its entries point to the qt install. I am using anaconda 4.1.6 on OSX, which created a correct config file, but I had to move it a bit to see the icons (i had to move it from anaconda/bin to anaconda/python.app/contents/resources).

[brylie]

I am using python -m Orange.canvas e.g. from my home folder. In what folder should I run the command? I will look for the qt.conf file.

[brylie]

I have three files named qt.conf:

• ~/anaconda3/pkgs/qt-4.8.7-3/info/recipe/qt.conf
• ~/anaconda3/pkgs/qt-4.8.7-3/bin/qt.conf
• ~/anaconda3/bin/qt.conf

[brylie]

I tried running python -m Orange.canvas from within the ~/anaconda3/bin/ folder. The icons still do not render.

[astaric]

I'll try to reproduce it on a Ubuntu 16.04 virtual machine.Can you tell me which version of conda are you using (conda --version), so I can make sure I am testing on the same configuration?

[brylie]

conda 4.1.4

[astaric]

I have installed conda 4.1.6 into a fresh Unbuntu 16.04 virtual machine. It created ~/anaconda/bin/qt.conf with the following content:

[Paths]
Prefix = /home/x/anaconda3/lib/qt4
Binaries = /home/x/anaconda3/bin
Libraries = /home/x/anaconda3/lib
Headers = /home/x/anaconda3/include/qt4

If I run a slightly modified script ales posted above (I have added one import and the app = ... line):

python - <<EOF
import os
import PyQt4
from PyQt4.QtCore import QCoreApplication
from PyQt4.QtGui import QImageReader, QApplication
app = QCoreApplication([])
print("PyQt4 installed in", os.path.dirname(PyQt4.__file__))
print("Qt4 library paths", QApplication.libraryPaths())
print([bytes(f).decode("ascii") for f in QImageReader.supportedImageFormats()])
EOF

it lists svg

PyQt4 installed in /home/x/anaconda3/lib/python3.5/site-packages/PyQt4
Qt4 library paths ['/home/x/anaconda3/lib/qt4/plugins', '/home/x/anaconda3/bin']
['bmp', 'gif', 'ico', 'jpeg', 'jpg', 'mng', 'pbm', 'pgm', 'png', 'ppm', 'svg', 'svgz', 'tga', 'tif', 'tiff', 'xbm', 'xpm']

[brylie]

Same here:

['bmp', 'gif', 'ico', 'jpeg', 'jpg', 'mng', 'pbm', 'pgm', 'png', 'ppm', 'svg', 'svgz', 'tga', 'tif', 'tiff', 'xbm', 'xpm']

[brylie]

@astaric, do your icons render?

[astaric]

They do.

I did not follow the installation guide though, since all the requirements have already been installed by anaconda. What I did after installing anaconda was just

conda install orange3
conda install joblib
conda uninstall orange3

(I used conda to install all orange3 requirements, but then uninstall the outdated orange3 package, as I will install the latest version in the next step)

git clone https://github.com/biolab/orange3
cd orange3
python setup.py install

Then I ran

python -m Orange.canvas

And got a proper canvas with icons.

[astaric]

Ok, I have managed to reproduce the problem, and found a way to fix it :)

Remove the orange3env folder that was created by the installation script. Then install orange3 with:

conda install orange3
pip install -U orange3

And you should have a working orange canvas with icons.

I will update the installation instructions on the website to give specific instructions for anaconda users.

[brylie]

Yay! thanks @astaric :-)

This hopefully gets us closer to simply having a menu item to click when launching Orange ;-)

[brylie]

For what it's worth, I was able to 'pin' Orange to my launcher menu after launching it the first time from terminal. However, the pinned icon does not work :-(

[brylie]

I opened a feature request for an application launcher on GNU/Linux (#1426).

[astaric]

The updated instructions should result in a working canvas, so I am closing this issue.

[eparimbelli]

It's still not working for me also following the updated instructions (ubuntu 14.04 though)
freshly installed anaconda 4.2.9

conda install orange3
pip install -U orange3

python -m Orange.canvas >> results in a canvas with no icon displayed

I'm missing the svg support though apparently... don't know how since conda fetched the correct qt4 for me (also asked to downgrade from qt5 to be compatible with orange when I ran conda install orange):

PyQt4 installed in /home/enea/anaconda3/lib/python3.5/site-packages/PyQt4
Qt4 library paths ['/home/enea/anaconda3/plugins', '/home/enea/anaconda3/bin']
