在OpenCV{Python}上使用AKAZE时，Get_MLDB_Full_描述符断言失败

Question

我在Python 3.8上使用AKAZE构造函数&OpenCV 4.4.0.44来自{}

我试图在构造函数中组合不同的参数，并计划在数据集上执行它们。 构造函数可以很好地使用其默认参数

请参阅代码和传递的不同值：

    # [ options is the argparser ]

    grayscale_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
    grayscale_image = cv2.resize(grayscale_image, (256, 256), interpolation=cv2.INTER_AREA)

    if mask is not None:
        mask = cv2.resize(mask, (256, 256), interpolation=cv2.INTER_AREA)
        mask = (mask == 0).astype(np.uint8) * 255

    # Options of the constructor
    #    - descriptor_type          Type of the extracted descriptor: DESCRIPTOR_KAZE,
    #                               DESCRIPTOR_KAZE_UPRIGHT, DESCRIPTOR_MLDB or DESCRIPTOR_MLDB_UPRIGHT.
    #    - descriptor_size          Size of the descriptor in bits. 0 -> Full size
    #    - descriptor_channels      Number of channels in the descriptor (1, 2, 3)
    #    - threshold                Detector response threshold to accept point
    #    - nOctaves                 Maximum octave evolution of the image
    #    - nOctaveLayers            Default number of sublevels per scale level
    #    - diffusivity              Diffusivity type. DIFF_PM_G1, DIFF_PM_G2, DIFF_WEICKERT or DIFF_CHARBONNIER

    # Assuring type is the expected for each one
    descriptor_size = int(options.ak_desc_size)  ## 0 = full size
    descriptor_type = int(options.ak_desc_type)  ## 5 or 4 or 3 or 2 descriptor
    threshold = float(options.ak_threshold)      ## variable (0.001)
    channels = int(options.ak_desc_chan)         ## with 3 works, not with 1 or 2
    num_octaves = int(options.ak_num_octav)      ## 4
    octave_layers = int(options.ak_oct_layer)    ## 4
    difussivity = int(options.ak_diffusivt)      ## 0..3
    akaze = cv2.AKAZE_create(descriptor_size=descriptor_size,
                             descriptor_type=descriptor_type,
                             threshold=threshold,
                             descriptor_channels=channels,
                             nOctaves=num_octaves,
                             nOctaveLayers=octave_layers,
                             diffusivity=difussivity)
    keypoints = akaze.detect(grayscale_image, mask=mask)

当我使用descriptor_channels == 2 or ==1 执行参数组合时，会出现以下异常：

cv2.error: OpenCV(4.4.0) /tmp/pip-req-build-6amqbhlx/opencv/modules/features2d/src/kaze/AKAZEFeatures.cpp:1986: error: (-215:Assertion failed) dpos == 486 in function 'Get_MLDB_Full_Descriptor'

我已经复习了Documentation，但我不知道我遗漏了什么

关于可能出现的错误有什么指导吗
