Good morning people I have a problem, that when I execute the code of my converted model, it gives shape error, I was wondering why mine doesn't work.

Hi Alexander,
Looking at your description, it sounds like you have custom trained YOLOv3 model from DarkNet.
- How did you convert your weights file to TensorFlow (.pb) and TensorFlow to IR format?
- Could you provide the commands?
- What TensorFlow version did you use for training and converting the weights file?
- Could you share the model for me to test from my end? I will also need your configuration file (.cfg).
Also, please try updating your OpenVINO toolkit to the 2020.1 release.
Regards,
Jesus

I am also having a similar problem with the samples. https://github.com/opencv/open_model_zoo/tree/master/demos/python_demos/text_spotting_demo

Hi,
I tried running Yolov4 and I a got a similar issue:
I'm using OpenVino 2020R4 with this code https://github.com/SadmiB/OpenVINO-YOLOV4/blob/master/object_detection_demo_yolov4_async.py
Regards.

ValueError: cannot reshape array of size 172380 into shape (1,18,26,26)- This one!
I am getting the same error.

I'm having this same issue with a custom trained yolov3/4 model :

Still looking for a solution
IR made with :
- Depth-AI Yolov4 colab
- converted to TensorFlow 1.14 + Keras 2.6.0
- converted to IR
