Error features_stride = float tensorflow model in opencv dnn

Python
1

was trying to make pbtxt file using my trained model and config file and got this error using tf_text_graph_mask_rcnn.py
opencv version 4.5.2

Traceback (most recent call last):
  File "E:\mask_rcnn_inception_v2_coco_2018_01_28\opencv\sources\samples\dnn\tf_text_graph_mask_rcnn.py", line 41, in <module>
    features_stride = float(config['feature_extractor'][0]['first_stage_features_stride'][0])
KeyError: 'first_stage_features_stride'

this is actually not from the dnn, but from a tf-based preprocessing script

please check your config file for the missing key first_stage_features_stride

@berak figured out the first stage feature_stirde and now new error

you’re using the wrong tf version

(2.0 is no more grapfdef based (iirc), try something older, like 1.5)

@berak sorry berak above link is tf2 this file , today i trained in tf1.15.0 with * mask_rcnn_resnet101_atrous_coco_2018_01_28
found from opencv wiki Enable Mask-RCNN models with dilated convolutions from TensorFlow by dkurt · Pull Request #13766 · opencv/opencv · GitHub
this is the latest file please take a look
opencvdnn - Google Drive
thanks

sorry, but i have no real idea about mask-rnn or tf, but if the model on your ggl drive is only 2mb, it’s probably broken (should be >500mb, iirc(which is why i never downloaded it))

@berak thanks berak let me check
