Error during pre-segmentation #2

Closed PetterRanefall closed 5 years ago

PetterRanefall commented 5 years ago

I get the following error when I try to run start_prediction_full.bat:

File "C:\Code\Python3\biomagdsb\FinalModel\segmentation.py", line 119, in Segment temp, , = cv2.findContours(temp, cv2.RETR_CCOMP, cv2.CHAIN_APPROX_SIMPLE) ValueError: not enough values to unpack (expected 3, got 2) ERROR: "Error during pre-segmentation"

@PetterRanefall - I am facing the same problem. Time being, I have forced IF condition to False. Not seeing any degradation as such.

@PetterRanefall @OpenCv30 Could you please check your OpenCV version? The project requires 3.4.2.17. The earlier releases returned 2 values only.

PetterRanefall commented 5 years ago

I have OpenCV 4.1.1.26

csmolnar commented 5 years ago

The function declaration has 2 return values again in this new version: https://docs.opencv.org/4.1.1/d3/dc0/groupimgprocshape.html#gadf1ad6a0b82947fa1fe3c3d497f260e0 Downgrading your OpenCV to the suggested version should solve your problem.

@PetterRanefall @OpenCv30 can you please confirm if the issue was resolved by @csmolnar's suggestion?

PetterRanefall commented 5 years ago

I suppose the issue is solved by downgrading, but I am not so keen on doing the downgrade.
