@anazkhan hello, Thank you for reaching out with your question on model distillation for YOLOv5! Model distillation is a powerful technique to transfer knowledge from a larger, more complex model (teacher) to a smaller, more efficient model (student). In your case, you want to distill knowledge from YOLOv5l (teacher) to YOLOv5n (student). While we don't have a dedicated guide for model distillation in YOLOv5, I can provide you with a general approach and some code snippets to get you started. Steps for Model Distillation
Additional ResourcesFor more detailed information on setting up your environment and running YOLOv5, please refer to our YOLOv5 Quickstart Tutorial. If you encounter any issues or have further questions, feel free to provide a minimum reproducible code example so we can assist you better. You can find more information on creating a reproducible example here. I hope this helps you get started with model distillation for YOLOv5! If you have any more questions, feel free to ask. |

Additional Tips
Feel free to reach out if you have any more questions or need further assistance. Happy training! 🚀 |
just want to clarify, 'from yolov5.utils.datasets import LoadImagesAndLabels' was module not found error but the same module was present in from yolov5.utils.dataloaders import LoadImagesAndLabels. |
data_config = check_dataset('data/data.yaml') train_loader = DataLoader(dataloader, batch_size=16, shuffle=True, collate_fn=dataloader.collate_fn) This is how i have created the data loader to train the student model. |

Hello @anazkhan, Thank you for your patience and for providing the detailed information earlier. I understand that encountering persistent issues can be frustrating, and I'm here to help you resolve this. Next StepsTo effectively diagnose and address the issue, let's ensure we have all the necessary details:
Debugging StepsLet's add some debug prints to check the contents of the dataloader and ensure everything is being loaded correctly: from yolov5.utils.general import check_dataset
from yolov5.utils.dataloaders import LoadImagesAndLabels
from torch.utils.data import DataLoader
# Load dataset configuration
data_config = check_dataset('data/coco.yaml')
# Create dataloader
dataloader = LoadImagesAndLabels(data_config['train'], img_size=640, batch_size=16, augment=True)
train_loader = DataLoader(dataloader, batch_size=16, shuffle=True, collate_fn=dataloader.collate_fn)
# Debugging: Check the first batch
for images, targets, paths, _ in train_loader:
print(f"Images: {images}")
print(f"Targets: {targets}")
print(f"Paths: {paths}")
break # Just to check the first batch Training Loop ExampleHere’s a sample training loop for reference: optimizer = torch.optim.Adam(student_model.parameters(), lr=1e-4)

teacher_outputs = teacher_model(images)
# Compute loss
loss = distillation_loss(student_outputs, teacher_outputs, targets)
# Backward pass and optimization
optimizer.zero_grad()
loss.backward()
optimizer.step()
print(f"Epoch [{epoch+1}/{num_epochs}], Loss: {loss.item()}") Additional InformationIf the issue persists, please share any specific error messages or additional details that could help us diagnose the problem more effectively. Your cooperation and patience are greatly appreciated. Thank you for your understanding. If you have any further questions or need additional assistance, feel free to ask! 😊 |
the debugging step you provided is not possible since the error persist in 'for images, targets, paths, _ in train_loader:' line. |
Hello @anazkhan, Thank you for your patience and for providing detailed information about the issue you're facing. I understand that the error persists at the line Next Steps
Additional Debugging StepsSince the error occurs at the dataloader iteration, let's add some checks before the loop to ensure the dataloader is correctly instantiated and contains data: from yolov5.utils.general import check_dataset
from yolov5.utils.dataloaders import LoadImagesAndLabels
from torch.utils.data import DataLoader
# Load dataset configuration
data_config = check_dataset('data/coco.yaml')
# Create dataloader
dataloader = LoadImagesAndLabels(data_config['train'], img_size=640, batch_size=16, augment=True)
train_loader = DataLoader(dataloader, batch_size=16, shuffle=True, collate_fn=dataloader.collate_fn)
# Check if dataloader is not empty
if len(train_loader) == 0:
print("Dataloader is empty. Please check your dataset paths and configuration.")
else:
print("Dataloader contains data. Proceeding with training loop.")
# Proceed with training loop
for images, targets, paths, _ in train_loader:
print(f"Images: {images}")
print(f"Targets: {targets}")
print(f"Paths: {paths}")
break # Just to check the first batch Training Loop ExampleHere’s a sample training loop for reference: optimizer = torch.optim.Adam(student_model.parameters(), lr=1e-4)
for epoch in range(num_epochs):
