ValueError: cannot reshape array of size 172380 into shape (1,18,26,26)

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.

Was anyone able to solve this issue? 

I am getting this error in yolov3 tiny model .

Has anyone manage to solve the issue? 

ValueError: cannot reshape array of size 172380 into shape (1,18,26,26)- This one!

I am getting the same error.

https://community.intel.com/t5/Intel-Distribution-of-OpenVINO/Running-Custom-IR-files-in-Video/td-p/... Here I mentioned about it.

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
