@AlvinBimo23 hello!
It looks like you're having an issue with image recognition during training. Here are a couple of things you could check:
-
Label Verification: Ensure that the images are labeled correctly in the corresponding annotation files (usually
.txt
files). Verify whether the class identifiers in the label files match those defined in the classes section of your.yaml
file. -
Path Format: Confirm the format of the paths specified in your
.yaml
file. They should be relative to the directory from which you are running the training command unless absolute paths are specified.
Here's a small example of how your .yaml
file should look:
train: ../data/images/train/ # path to training images
val: ../data/images/val/ # path to validation images
nc: 1 # number of classes
names: ['YourClassName'] # class names
- File Reading Permissions: Sometimes, issues on specific platforms or environments like
vast.ai
could be related to reading permissions. Ensure that your dataset directory has the appropriate read permissions.
If the problem persists, consider including the content of your .yaml
file and possibly a snippet of your data structure (e.g., a directory tree or a few lines from your annotation files). This can help diagnose the issue more effectively. ๐ ๏ธ
Best of luck!

Hi there, to give more context about my problem. I was using a dataset that i download from roboflow and i tried use itu to train my model and it works, but the problem is the split data ratio are not what i need so I was trying to try split it with my prefered ratio. First i combine all image in one folder and all label in one folder and then i split it manually, the split process are succesful. But when i tried to use the data, the model didnt recognize the all the image file as 'image' but as 'background'. My theories are the model didnt recognize the label data, but i already made sure that all the image file in respective folder has a label file in label folder. Is there any alternative or solution for this ?
*Note : This is my split code
import os
import shutil
import random
from pathlib import Path
def split_data(source_folder, label_folder, train_ratio=0.6, val_ratio=0.2, test_ratio=0.2):
# Convert to Path objects for better path handling
source_folder = Path(source_folder)
label_folder = Path(label_folder)
# Create train, val, test directories
for split in ["Train", "Val", "Test"]:
os.makedirs(Path(split) / "image", exist_ok=True)
os.makedirs(Path(split) / "label", exist_ok=True)
# Get list of files in source folder
files = [f for f in source_folder.glob("*.jpg")]
random.shuffle(files)
# Split files into train, val, test sets
num_files = len(files)
num_train = int(train_ratio * num_files)
num_val = int(val_ratio * num_files)
train_files = files[:num_train]
val_files = files[num_train:num_train + num_val]
test_files = files[num_train + num_val:]
# Function to move files
def move_files(file_list, image_dest, label_dest):
for file in file_list:
shutil.copy(file, image_dest)
label_file = label_folder / file.with_suffix(".txt").name
if label_file.exists():
shutil.copy(label_file, label_dest)
# Move image and label files to respective directories
move_files(train_files, "Train/image", "Train/label")
move_files(val_files, "Val/image", "Val/label")
move_files(test_files, "Test/image", "Test/label")
Specify source folder and label folder
source_folder = "comb_img"
label_folder = "comb_lbl"
Call the function to split the data
split_data(source_folder, label_folder)

Hi @AlvinBimo23! It looks like you've encountered an issue where the model does not recognize the images as expected and instead treats them as 'background'.
Given that your labels are correctly paired with the images in their respective folders, here's a couple of things you may check:
- File Path Consistency: Ensure the paths in your
.yaml
file correctly reference the new split directories. Check that they point to theTrain/image
,Val/image
, andTest/image
folders for images and their corresponding label folders.
train: /path/to/Train/image
val: /path/to/Val/image
nc: number_of_classes # Light check if classes number is correct
names: [list_of_class_names] # Again, ensure this accurately reflects class labels
-
Label File Format: Confirm the format of your label files (
.txt
) and make sure they are consistent with the expected YOLO format, which is class id, followed by bbox center x, y normalized by image width, height, and width, and height of bbox also normalized. -
Precision of Train Test Split: Double-check your split ratios and make sure that each segment (train, val, test) contains both images and their respective labels correctly. Any mismatch here might cause the background-only detection issue.
It might help to visual inspect some of the label files to ensure they are not corrupted or incorrect post-manual splitting. If the configuration seems correct and you're still facing issues, consider a debug step where you sample and manually check a few label-image pairs from each of the splits to verify the correctness.
Hope this helps! Let me know if there's any improvement or further issues! ๐ต๏ธโโ๏ธ
