Error loading maskrcnn in opencv dnn

Python
1

Created .pbtxt using this code (dkurt (Dmitry Kurtaev) · GitHub) tried this solution didn’t worked for me #16622
link to pb file mask_rcnn_landing.pb - Google Drive
pbtxt file
model.pbtxt - Google Drive

code i tried to generate pbtxt file

import tensorflow as tf

with tf.gfile.FastGFile('data/gaze_model.pb', "rb") as f:
    graph_def = tf.GraphDef()
    graph_def.ParseFromString(f.read())

    for i in reversed(range(len(graph_def.node))):
        if graph_def.node[i].op == 'Const':
            del graph_def.node[i]

    graph_def.library.Clear()

    tf.train.write_graph(graph_def, "", 'data/gaze_model.pbtxt', as_text=True)

error loading to opencv dnn
and loaded my .pb and generated pbtxt file to opencv dnn ang got error

Failed to parse GraphDef file: E:/model.pbtxt in function 'cv::dnn::ReadTFNetParamsFromTextFileOrDie'
