python - 在 Paraview 的自定义过滤器中导入日志记录

Question

我有一个自定义过滤器，我一直在尝试添加日志记录，但无法使其工作，Paraview GUI 不断崩溃，我不知道为什么。

我尝试过类似的东西

import vtk
import math
import numpy as np
import numpy.linalg as la

from vtkmodules.util.vtkAlgorithm import VTKPythonAlgorithmBase
from vtkmodules.vtkCommonDataModel import vtkDataSet

from paraview.util.vtkAlgorithm import smproxy, smproperty

from vtk.numpy_interface import algorithms as algs
from vtk.numpy_interface import dataset_adapter as dsa
import logging

logging.basicConfig(filename='app.log', filemode='w', format='%(name)s - %(levelname)s - %(message)s')
logging.warning('This will get logged to a file')

@smproxy.filter(label="Custom Markers Filter")
@smproperty.input(name="Input")
class CustomMarkersFilter(VTKPythonAlgorithmBase):
    def __init__(self):
        VTKPythonAlgorithmBase.__init__(self)

    def RequestData(self, request, inInfo, outInfo):
        logging.info('Requesting Data')
        inp = vtkDataSet.GetData(inInfo[0])
        dsaInp = dsa.WrapDataObject(inp)

        points = dsaInp.GetPoints()

        centers = identify_markers(points)

        M1_, M2_, M3_ = centers
        print("M1': " + str(M1_))
        print("M2': " + str(M2_))
        print("M3': " + str(M3_))

        # Create vtkPoints from markers centers
        pts = vtk.vtkPoints()
        for p in centers:
            pts.InsertNextPoint(p)

        opt = vtkDataSet.GetData(outInfo)
        dsaOpt = dsa.WrapDataObject(opt)

        opt.SetPoints(pts)

        numPts = pts.GetNumberOfPoints()

        ptIds = vtk.vtkIdList()
        ptIds.SetNumberOfIds(numPts)
        for a in range(numPts):
            ptIds.SetId(a, a)

        dsaOpt.Allocate(1)
        dsaOpt.InsertNextCell(vtk.VTK_POLY_VERTEX, ptIds)

        return 1

我也尝试在类内部进行初始化，但也没有成功。

即使应用程序崩溃，有没有办法获得反馈？
