impossible to save : float division by zero

[lucydjo]

Hi,

Does not want to record labels. I have tried with several versions, nothing works.
How to fix ?

I only have two very large images. High-precision satellite photo (15kX15k). I have to get more than 1000 labels per photo

Img: C:\Users\wkn\Documents\IA\ortoIA\images\png5ca3a3d5e5635f000690af6b.png -> Its txt: C:\Users\wkn\Documents\IA\ortoIA\labels\png5ca3a3d5e5635f000690af6b.txt

Thx !

i faced the same problem, this happens due to transparency in the some images, i dnt know what kind of transparency is this,......but it can be solved by opening the image with opencv and saving it again, it worked for me.

i wrote this python file :--

import cv2
import os

def loadImages(path = "."):

return [os.path.join(path, f) for f in os.listdir(path) if f.endswith('.jpg')]

filenames = loadImages()
images = []
for file in filenames:
images.append(cv2.imread(file, cv2.IMREAD_UNCHANGED))

num = 0
for image in images:
cv2.imwrite(str(num)+".jpg",image)
num += 1

it will open every file in the directory and save it again!!

What image format are you labelling? I had the same error when I was labelling .png images. It only worked for me with .jpg images.
