[REVIEW] Figure not showing #28

Open ClaudMor opened 1 week ago

ClaudMor commented 1 week ago

Dear authors,

If I run your tutorial on Visualizing Networks, the figure does not show:

from pymnet import *
net = models.er_multilayer(5,2,0.2)
fig = draw(net,show=True)
C:\Users\claud\anaconda3\envs\pymnet_review\Lib\site-packages\pymnet\visuals\drawbackends\mpl.py:79: UserWarning: FigureCanvasAgg is non-interactive, and thus cannot be shown
  plt.show()

I tried installing PyQt6 (as suggested here) to no avail.

Would you have any idea on what could the problem be (perhaps it is related to my machine or environment)?

Hi! The error message typically happens when the default backend does not support interactive plotting. But you have already installed PyQt6, so it seems the backend is not set correctly. To resolve this, I suggest following steps, respectively!

  1. Ensure that the backend is available in your environment: 
    import matplotlib
print(matplotlib.rcsetup.all_backends)
  2. Ensure PyQt6 is Installed Correctly: 
    from PyQt6.QtWidgets import QApplication, QLabel
app = QApplication([])
label = QLabel("Congratulation!!!!!It's Okkkk")
label.show()
app.exec()
  3. Ensure that Matplotlib is set to correct backend: 
    
import matplotlib
matplotlib.use('QtAgg') #or'Qt5Agg'

from pymnet import * net = models.er_multilayer(5, 2, 0.2) fig = draw(net, show=True)

4. Use Environment Variables:
```bash
export MPLBACKEND=QtAgg  #Unix-based
set MPLBACKEND=QtAgg  #Windows or'Qt5Agg'
  1. Update All Packages: 
    conda update --all
  2. Test in a Different Environment: 
    conda create -n test_ python=3.12 matplotlib pyqt6 pymnet
conda activate test_

Hi @cloner174 , I tried all your steps, but still it doesn't work. More details below.

  1. print(matplotlib.rcsetup.all_backends)

    yields

    <stdin>:1: MatplotlibDeprecationWarning: The all_backends attribute was deprecated in Matplotlib 3.9 and will be removed 
in 3.11. Use ``matplotlib.backends.backend_registry.list_builtin()`` instead.
['gtk3agg', 'gtk3cairo', 'gtk4agg', 'gtk4cairo', 'macosx', 'nbagg', 'notebook', 'qtagg', 'qtcairo', 'qt5agg', 'qt5cairo', 'tkagg', 'tkcairo', 'webagg', 'wx', 'wxagg', 'wxcairo', 'agg', 'cairo', 'pdf', 'pgf', 'ps', 'svg', 'template']
  2. import matplotlib
matplotlib.use('QtAgg') #or'Qt5Agg'

Gives no output (so maybe it works).

  1. and 5. After entering 
    set MPLBACKEND=QtAgg

and retrying to draw with show=True it still doesn't show. Same for conda update --all.

The env is:
