Got error white coverting to IR using mo.py

[tarunmcom]

I downloaded yolo-v4-tiny.weights and converted to pb using provided script. But got error in the next step:-

Model Optimizer version:
[ ERROR ] Exception occurred during running replacer "TFYOLOV3" (<class 'extensions.front.YOLO.YoloV3RegionAddon'>): TensorFlow YOLO V3 conversion mechanism was enabled. Entry points "detector/yolo-v4/Reshape, detector/yolo-v4/Reshape_4, detector/yolo-v4/Reshape_8" were provided in the configuration file. Entry points are nodes that feed YOLO Region layers. Node with name detector/yolo-v4/Reshape doesn't exist in the graph. Refer to documentation about converting YOLO models for more information.

Please help

Hi @tarunmcom
That's because you still use yolov4.json.Please use yolo_v4_tiny.json instead

I have encounter a similiar error.when i use the yolo_v4_tiny.json,I got
[ ERROR ] Exception occurred during running replacer "TFYOLOV3" (<class 'extensions.front.YOLO.YoloV3RegionAddon'>): TensorFlow YOLO V3 conversion mechanism was enabled. Entry points "detector/yolo-v4-tiny/Reshape, detector/yolo-v4-ti

thanks for your help!

@su26225
So which model are you using?
YOLOv4 or YOLOv4-tiny

[su26225]

@su26225
So which model are you using?

I use yolov4-tiny.weights,after the train of darknet

[TNTWEN]

@su26225
check the .pb model you are using
The error means the .pb model isn't converted by your yolov4-tiny.weights
OR you can list all commands here

[TNTWEN]

python convert_weights_pb.py --class_names cfg/coco.names --weights_file yolov4-tiny-custom_last.weights --data_format NHWC

you didn't add --tiny

[su26225]

@su26225
check the .pb model you are using
The error means the .pb model isn't converted by your yolov4-tiny.weights
OR you can list all commands here

This is the cammands I used:
./darknet detector train /data2/darknet-master/build/darknet/x64/data/obj.data cfg/yolov4-tiny-custom.cfg /data2/darknet-master/yolov4-tiny.weights -map
python convert_weights_pb.py --class_names cfg/coco.names --weights_file yolov4-tiny-custom_last.weights --data_format NHWC
python "C:\Intel\openvino_2021.3.394\deployment_tools\model_optimizer\mo.py" --input_model frozen_darknet_yolov4_model.pb --transformations_config yolov4.json --batch 1 --reverse_input_channels

If I use the yolov4.json,I will get the error:
[ ERROR ] Cannot infer shapes or values for node "detector/yolo-v4/Conv_23/biases".
[ ERROR ] Attempting to use uninitialized value detector/yolo-v4/Conv_23/biases

[ ERROR ]
[ ERROR ] It can happen due to bug in custom shape infer function <function tf_native_tf_node_infer at 0x0000014FFAA861E0>.
[ ERROR ] Or because the node inputs have incorrect values/shapes.
[ ERROR ] Or because input shapes are incorrect (embedded to the model or passed via --input_shape).

This is also wrong

python convert_weights_pb.py --class_names cfg/coco.names --weights_file yolov4-tiny-custom_last.weights --data_format NHWC --tiny

I got it . I used the convert_weights_pb.py in branch of v4-tiny-3l , it doesn't have the flag.tiny.
Howevey , when i changed to use convert_weights_pb.py in master
python convert_weights_pb.py --class_names cfg/coco.names --weights_file yolov4-tiny-custom_last.weights --data_format NHWC --tiny

I got the error :

How many classes your custom model has?
you should change number of classes in .json which has been mentioned in FAQ

[su26225]

yes,I have changed the number of classes from 80 to 2 , but it still have the error .
I try to run the program in Linux , and then I get the .xml 、 .bin , although I don't know why

python convert_weights_pb.py --class_names cfg/coco.names --weights_file yolov4-tiny-custom_last.weights --data_format NHWC --tiny

you still use coco.names here

[su26225]

you still use coco.names here

I have chaned the content of coco.names . It has only two labels in it .
Now , I am still traped in the step of mo.py.
Should I follow this branch of tiny.3l exactly for deployment , or switch to the master?

[TNTWEN]

It's clear that yolov4 and yolov4-tiny use master branch,yolov4-tiny-3l use tiny-3l branch
And all commands are listed in corresponding README in detail.
I recommend you download yolov4.weights yolov4-tiny.weights and try official model first.
You should make sure you could run demo first

And then you only need to change coco.names and .json for custom model.

Thanks . I have solved this issue through upgrading tensorflow version from 1.15 to 2.0
