Issues with start code

[FranzEricSchneider]

After installing in a conda environment with conda install pyqglviewer -c fredboudon -c conda-forge, I had the following issues with the starter code:

I believe PyQGLViewer is installed as shown, but qgllogo is unavailable, and I could not find it mentioned on the internet:

In [1]: from PyQGLViewer import *

In [2]: from qgllogo import draw_qgl_logo
---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Cell In[2], line 1
----> 1 from qgllogo import draw_qgl_logo

ModuleNotFoundError: No module named 'qgllogo'

Next the QApplication seems to not some from the given imports, maybe it moved around in the Qt library?

In [3]: from PyQt5.QtGui import *

In [4]: qapp = QApplication([])
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
Cell In[4], line 1
----> 1 qapp = QApplication([])

NameError: name 'QApplication' is not defined

In [5]: from PyQt5.Qt import QApplication
