@@RoboflowIs there any way to detect in a video ?
Great tutorial. I'm going to train Detr on a custom medical dataset with x-ray images to detect bolus, stent, catheter, etc. Hopefully this will turn out to be fruitful. There hasn't been much research using Detr on medical datasets yet.
Best ever Deep Learning video I have found. please make such video
Is there reason in particular why you install a spesific verison of supervision (i.e. supervision==0.3.0) ?
Hey, This is a great lesson, do you have any idea that this way we can also train Grounding Dino on our custom dataset?
annotations are not found during the evaluation process any way out for this model
Would you be a bit more specific?
Great Video. I resonate with your intro, on how it's hard not to get imposter syndrome in this fast changing AI/ML landscape, when you don't know how to implement the latest "thing".
Thanks a lot. At the same time there is nothing better than just to face your latest “thing” and learn!
Hey Roboflow bro! I found this vidio really helpfull and I have a question striking me: where to use the checkpoint, I want to load the model using checkpoint that got saved while logging inside lightning_logs and not by the config file saved in custom-model directory; is there a way?

please guide me how i can increase my value upto 95%. i use same parameter that you have used in your video.i will be very thankful to you
Did you used the same dataset we did?
I used the "SeaShip" dataset, downloaded from the Roboflow website, which consisted of 7,900 training images and approximately 1,661 validation images. For both the train_dataloader and val_dataloader , I set the batch size to 4. training and model parameters was:
model = Detr(lr=1e-4, lr_backbone=1e-5, weight_decay=1e-4)
trainer = Trainer(devices=1, accelerator="gpu",
max_epochs=50,
gradient_clip_val=0.1, accumulate_grad_batches=8, log_every_n_steps=5)
on these i received the results that i have uploaded in my first comment.
I again starts a second training iteration with significant adjustments to hyperparameters. In this instance, I enlarged the training dataset to 9,843 images while simultaneously reducing the validation dataset to a mere 300 images., also increase the epochs up to 100 and for train_dataloader batch_size=4 and for valid_dataloader batch_size=2, also reduce the learning rate from lr=1e-4 to lr=1e-5.
during first time total training time was 23 hours but this time my training is still running from last 18 hours it will take one more day i think.after that i will share the result again. and one more thing i have NVIDIA rtx 6000 (24GB)
@@Roboflow Second time accuracy comes 81% how can i increase the accuracy.
Thank you for your tutorial.❤
Let me know how to use this trained model for test an image thats not in test dataset.
Can this be applied to realtime surveillance cameras to detect shoplifting?
I am getting the 'Key Error'='annotations'
And Type of Error: Detections.___Getitem__ not supported for index of type ....
Please Do guide me with the following error how can i come up with it.
Will really appreciate it.
Thank you so much for this tutorial!
I am getting this error:
KeyError: 'annotations'. I think this is because "predictions" is an empty dict, so is "results". However "orig_target_sizes" is not empty. I have tried with 20 epochs, is it because the model is not learning well enough to be able to actually make predictions? Furthermore, I tried to annotate images in the train and val datasets, and I am not seeing any detected boxes around the objects (when comparing to the ground truth) Would rly appreciate some help regarding this issue!
Could you create new issue here: github.com/roboflow/notebooks/issues and describe all those issues.
Bruh i am also getting this type of error continuously please if you have come up with it guide me too. Will really appreciate ❤ Thanks
AttributeError: 'ToTensor' object has no attribute 'pad' that How to solve this problem ?
Hello, the acuial purpose of DETR is to ELIMINATE the use of NMS. But your code uses NMS. why?. obtained from the original paper:"Our approach streamlines the detection pipeline, effectively removing the need for many hand-designed components like a non-maximum suppression procedure or anchor generation
that explicitly encode our prior knowledge about the task"- PLEASE EXPLAIN
The answer is pretty simple. I run the model and faced a lot of problems with double detections. Results were pretty much unusable without NMS and that’s why I added it.
Thank you for such a great tutorial! I have learnt a lot. And I also watched other videos you made. They really helped me understanding the models and training process better.
About the false detection you mentioned, I came acorss similar problems on my dataset. I'm thinking maybe add null images to the dataset (about 10%) could help? I am just about to try!
Excellent video. Thanks!!
amazing tutorials
keep it coming
Thanks a lot! Stay tuned. I already have idea for next one ☝️
NameError: name 'image_processor' is not defined
Hi, first thanks for this great work, I am having a problem if I try to create this notebook on my development server, when I use "inputs=image_processor(images=image,return_tensor='pt').to(DEVICE)" (device(type='cuda', index=0)) I get in transformers/feature_extraction_utils.py:229 "TypeError: is_floating_point(): argument 'input' (position 1) must be Tensor, not list" any help will be very appreciated
great video, thanks!
Pleasure!
hey any idea on how to use pretrained detr
Loved it!! have you tried using DETR with Detectron2?
BTW, it wasn´t long for me. Very precise learned a lot!
Thanks a lot for that positive feedback. I actually didn’t trained DETR with Detectron2. I came a bit late to the party and went straight with Transformers.
Thank you so much for the great video! Your quality content has helped me a lot in my thesis ☺. Just wanna ask, can we apply our trained model to predict a video/webcam directly?
Not entirely “directly” but you can use tools in Supervision to process video
@@Roboflow Ah I see, is the concept the same as your video about detect and count object in polygon zone?
@@arfashaha4074 yes exactly! Generate frames from video. Process frame. Annotate. Save to result file.
@@Roboflow Perfect, thanks for the help! You've been wonderful
@@arfashaha4074 thanks a lot for kind words!
I tried to use it with my own model, but it said "NameError: name 'image_processor' is not defined" in the first code cell of "Create COCO data loaders

Is there any way to detect in a video ?
Great lesson
Nice video. Can you please tell how to run the training on multi-gpu? Which lines to be added or modified?
Hi, very informative video! I’ve been working with DETR for mitosis object detection and your code has been of great help. But when im training the model, the loss is decreasing very very slowly. Like even after 50 epochs my loss has gone down from 3.7 to 3.1 . So I was thinking maybe it’s coz of the learning rate. Is there any way I could change the learning rate coz when I tried doing that during DETR class instantiation, it threw an error while error. So as of now I can’t change the learning rate and my loss is almost stabilized at 3 and just fluctuating between the above mentioned values. Appreciate your reply :))
which object detection model is best for accuracy, Yolov8, dert, transofrmer or Faster RCNN?
You only care about top accuracy? Speed does not matter? Or top accuracy in real time detection?
@@Roboflow Thanks for the great content.
How about each use case?

What is the impact of small batch sizes on inference accuracy? - I only have 8gb of vram on my 3060ti and for the larger models I’m only getting batch sizes of 1 or 2.

You can convert the model to ONNX and in this format it is deployable on Android Phones. Maybe there are other ways, but I’m pretty sure this one should work.

@@user-qh8zh3fx8n no problem! 😉
great content! I have tried using it on my own dataset but the labels were not correct with the coco format, although i tried yolov5 and it did good . any explanation for that ?
Boxes were detected but with incorrect labels?
@@Roboflow yes that"s exactly what happened
my dataset contains numbers stamped on metal in a curved way, the model was detecting the boxes but with the wrong labels in this case, but it worked fine when i tried yolov5
@@mahachaabene6750 any pattern? Some numbers are always generated as other number? Maybe there is some mapping problem?

How do I count the various objects in the photo?
You can do it quite easily, for example like that:
count = len(sv.Detections.from_transformers(transformers_results=results))
@@Roboflow And how do I determine the number of objects for each class in the photo?
@@user-dk2rx7wu2k we do not have that functionality yet, but I'll add it to our roadmap. In the meantime you can do something like that:
{
int(class_id): len(detections[detections.class_id == class_id])
for class_id
in np.unique(detections.class_id)
}
@@Roboflow Thank you very much!
hello good afternoon, is it possible to detect objects and that the bounding box has a rotation?
What do you mean by retention?
Generally if you want more accuracy than a horizontal bounding box, I feel most people opt to use Segmentation instead of Bounding Boxes, since Bounding Box is meant to just have XY center position with Width Height (to minimize model output needed to identify the object)
@@raymond-andrade I’m still not sure if that was the original question, but if so than I agree.
Is there any way to detect in a vedio
Yes! you can use process_video function from supervision package: roboflow.github.io/supervision/video/#process_video to automatically process every frame from video.
@@Roboflow the link leads to nowhere. Please, can you check again? I'd appreciate if you can do that.
Also, how can one see the mAP, F1 and Recall from the training and validation?
how inference time for each frame of video?
You should be able to get around 20-25 fps with ResNet50 backbone.
