circular import

[PBrockmann]

I get a ImportError: cannot import name 'BackgroundPlotter' from partially initialized module 'pyvistaqt' (most likely due to a circular import) (/home/brock/pyvistaqt.py)

with simplest test code:

import pyvista as pv
from pyvistaqt import BackgroundPlotter

sphere = pv.Sphere()

plotter = BackgroundPlotter()
plotter.add_mesh(sphere)

Installed at release as:

pyvista                   0.43.3             pyhd8ed1ab_0    conda-forge
pyvistaqt                 0.11.0                   pypi_0    pypi

Any idea how to fix that ? Regards

After having installed in my conda environment PySide6 with pip install pyside6, the following basic exemple works.

import sys
import os
#os.environ["QT_API"] = "pyside6"
from qtpy import QtWidgets
import numpy as np
import pyvista as pv
from pyvistaqt import QtInteractor, MainWindow

class MyMainWindow(MainWindow):

    def __init__(self, parent=None, show=True):
        QtWidgets.QMainWindow.__init__(self, parent)

        # create the frame
        self.frame = QtWidgets.QFrame()
        vlayout = QtWidgets.QVBoxLayout()

        # add the pyvista interactor object
        self.plotter = QtInteractor(self.frame)
        vlayout.addWidget(self.plotter.interactor)
        self.signal_close.connect(self.plotter.close)

        self.frame.setLayout(vlayout)
        self.setCentralWidget(self.frame)

        sphere = pv.Sphere()
        self.plotter.add_mesh(sphere)

        self.show()


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = MyMainWindow()
    sys.exit(app.exec_())
