Let me know which custom classes you are training your custom detector on! As always comment if you run into any issues. Cheers :)
how to count plate in real time video sir?
Would love a video on Deep Sort + YOLOv4
I started training dataset containing wheat images in colab and colab's runtime is just stopped at 1961 iteration inspite of setting setting javascript code in console. Can you please suggest any way we can prevent it so that training continues?
prateek gupta that can sometimes happen due to memory issues within the notebook after running for a long time. Just restart training from saved weights and you will be good as new!
When I am running the first step in step 5, it shows this. What should I do?
CUDA Error: out of memory
CUDA Error: out of memory: File exists
darknet: ./src/utils.c:326: error: Assertion `0' failed.
I just saw that this video was posted. I was literally following your tutorials over the last few days to build a license plate detector for my University Major Project. You may have just saved my life, I'll be watching this video later
Perfect timing haha. Hope it helps, let me know if you need any help!
@@TheAIGuy An update on my project. Everything went well in my presentation besides a few questions on logistics. Thanks to you, it looks like I've passed my Major Project, the most important module to graduate from my university in Jamaica. All that's left to do is finish 2 modules to meet the credit requirements to graduate. Thank you for your video, it really helped me out of a tough spot
@@brandonchung5305 hello! Would you be open to sharing the code? I'm working on a similar project and i am a bit stuck. Or if possible, would you be open for a chat??
@@CJ-wk1xj Hey, send me a message on Discord at DeltaHarbinger#7582. I'll respond in a few hours
@@brandonchung5305 i just did :)
You teach better than paid courses which I've been taking for a couple of months. Please keep up the good work, thank you very much, you're teaching me a lot!
This is exciting, I was finally able to use your tutorial to train and test a working detector! you are making machine learning accessible to someone without a background in it, and I appreciate that. I only trained a small model (I did a beer detector lol), but this will be a great foundation for a larger paper I'm working on for my undergraduate final project. Thanks again!
You are a life saviour! I have a senior project and had to train a model on custom data, your notebook and explanation literally saved me! Fr! I learned from you more than 3 college courses of ai, thank you so so much
Hi! First of all I want to thank you for all your videos and the way you share your knowledge, that is invaluable and appreciated!
A while ago, I trained a single class with YOLOv3 to detect Argentine license plates (the old ones and the new ones) with 340 images. Of the 340 images you can detect 339, there is always one that does not detect it, it does not matter. I have done it because I wanted to try a Raspberry Pi and a webcam, do license plate recognition to recognize the characters and save them in a database, and that's where I am limited with my knowledge. Once I recognize where the patent is and draw a frame around it (already done), I need to extract it, correct its perspective, and do the OCR. I have seen that there exists YOLO, Tiny YOLO, Tensor Flow, Kereas, etc, and all of them using OpenCV; and the truth is that I already got lost. In your experience, what would be the ideal path to follow for a modest project like the one I want to do? Thank you very much.
I would recommend OpenCV with python. You can save the YOLOv4 detections and then run the OCR on the saved image. I will try and create a video showing how to do this on my license plate detector.
@@TheAIGuy I'll be looking forward for your video!
@@TheAIGuy can you make relatime ocr? so yolov4 detection and make it to OCR too iin one network
@@TheAIGuy Please make video on extracting licence plate only from this image and applying OCR pytesseract on same..also for video as well.. please sir
@@TheAIGuy Sir, your videos are really helpful.i really appreciate your efforts and work.
Thank you so much
This is such a useful video. Extremely helpful and well documented notebook:)
Glad it was helpful! Thanks for the kind words.
Hands down the most concise and practical YOLO tutorial I've seen anywhere!
Waiting for this so far! Thank you!
You're such a life savior. Stay Blessed !
You just made my day even better ! =)
One of the most useful and comprehensive videos I have watched in a long time. A lot of videos leave out important detail. Thank you.
Thanks, this tutorial still works as of 2/28/2022. The only issue is that Step 5 may not work on a free GPU instance. Google Colab offers plans to access High-RAM GPUs at $9.99/month. I bought the subscription, changed the runtime to a High-RAM GPU, and Step 5 worked for me.
Best Content and Best Explanation on Internet, Immediately subscribed to your channel when u started explaining the datasets making ..... BEST
amazing tutorial dude! You smashed DEEPLEARNING into a piece of cake!
Man you are just awesome...couldn't find multiple subscribe button..Thank you so much
@The AI Guy Thanks a lot for this video. I have trained the model on Custom Dataset of Retail Receipt Detection. It's working fine.
But I think my model is over fitted. I have early stop the training at 1100 iteration.
This is the MAP of my checkpoint.
Done! Loaded 162 layers from weights-file
calculation mAP (mean average precision)...
Detection layer: 139 - type = 27
Detection layer: 150 - type = 27
Detection layer: 161 - type = 27
152
detections_count = 172, unique_truth_count = 150
class_id = 0, name = retailReceipt, ap = 99.09% (TP = 149, FP = 2)
for conf_thresh = 0.25, precision = 0.99, recall = 0.99, F1-score = 0.99
for conf_thresh = 0.25, TP = 149, FP = 2, FN = 1, average IoU = 83.67 %
IoU threshold = 50 %, used Area-Under-Curve for each unique Recall
mean average precision (mAP@0.50) = 0.990915, or 99.09 %
Total Detection Time: 8 Seconds
I would like to thank you for this video and the collab notebook you single handedly saved my final year project. And i hope you are doing well man. Keep up the good work you are the best
Thanks a lot. Been stuck at this for last few days. Great video. The backup part is awesome.
Thank you! your tutorial is definitely one of the best if not the best!.
Thanks so much! Much appreciated.
I need to thank you for your job, it's obvious that this didn't worked everything as expected and I ended up solving many problems all along the training, but that's how we make science, discovering and understanding; Of course that without you it would be a LOT harder, thank you, I finally trained my first model!
Thanks bro .Your videos are just amazing .I just want to suggest that kindly make video regarding test data on custom trained model and also a video regarding description of the output of yolo v4.Other than that you are just amazing
Appreciate it. Thanks for the great ideas, noted them down for future videos.
@@TheAIGuy So nice of you. Great work my friend👌🏻
wow!! such value in every video! huge fan of your page: )
This video has helped me a lot :D. Congratulations on the tutorial!! Will you make a video on how to build an Object Tracker using YOLOv4? I think it would be interesting and would help a lot of people to develop different applications.
Great idea on the object tracker with YOLOv4! Will definitely cover this in a future video!
I second this!
Thanx man, it works like a charm. Looking forward for more tutorials
Glad you got it working. Thanks for the support!
Fantastic you nearly done my entire final year project😁, would you do YOLOv4 and Deep SORT for multi-object tracking in the future? I know you did YOLOv3 and Deep SORT and you nailed it.
Will definitely cover this soon! Thanks for the support.
Hi !
Your tutorial is awesome. You have done a lot of hardwork to make this tutorial.
Thank you so much.
Man, I love you! You have no idea of how much you help me! Thanks!
That was exactly what I was looking for!
thx mate :)
Man your notebook was very very helpful to me cheers...
I really like the intro box animations; it's super cool
New content I got from your video, thanks 4 sharing.
Thank you! your tutorial is definitely one of the best if not the best!. helped me a lot
Here we are! My Guy* with another trendy trend huh? Good job, thanks for the share! :D
Thanks!! Great TH-cam videos and you are very good at explaining
Thank you so much for making such a great video ! I learned a lot in this video, I gain lots of practical experience from it. Thank you so much !!!!
As usual a really helpful tutorial, just wanted a suggestion how to store all the detected object co-ordinates from the video in a Jason file for further processing.
I love your tutorials. they are just amazing. If possible could you please show training of GPT , BERT or XLnet
This video has saved my life! Much respect, thanks a lot for all the time and effort you put into your videos.
Ive trained a model to identify a pallet of boxes. I have a question, would it be possible to have a video and track an object, in my case a pallet, and then perform a some edge detection or detect another class of objects ONLY within the bounding box of the identified pallet? Basically I'm wanting to count the number of boxes on the pallet and I have it working with images, but video is the next step.
Any advice would be awesome.
Have you tried YOLO+ deepsort?
It was a great tutorial.
Thank you so much...!
Thanks for your tutorial ! It helps me a lot .
My friend you are a very good person.
Really thank you!! It have been help me a lot in my final paper!
thank you, I got to learn so much from this video!!!
Thanks for the very clear explanation.
wow thanks for making such a great tutorial.
You deserve a million subscribers.
Love your tutorials much better then the paid udemy tutorials
Thanks a lot for this amazing tutorial, I really appreciate your efforts in preparing this wonderful video and this detailed notebook, god bless you :)
Amazing video, very clear ! Thank you
THis is really helpful, thank you so much.
fantastic video
Do a playlist for Yolov5 as well please...
Hi, I could learn so many things in YOLO through your TH-cam!
Now, I also want to see the tutorial on applying the model to the webcam.
Do you have a plan to make tutorial about applying the model to the webcam?
I hope so!
another great video!!thanks!!!
Great tutorial! thanks!
Very useful video!
Thank you!
Amazing vdo sir ❤️
Thanks for the video, I learned alot from it. Just wondering how can I change so the prediction image doesn't only include border but it also shows the percentage of confidence.
Awesome tutorial! Class!
btw, how to show the probability of each bounding box?
I'm loving this video, it saved me! One question, do you know of anyone using YOLO for fire or smoke detection?
Thanks for the kind words! I have not heard of anyone using YOLO for fire or smoke detection, sounds like an awesome idea for an application though!
One of the best videos on yolov4...
Thanks for explaining it so well
I have a small doubt... can we change the batch_size=2 and image_size=1024??
If we can do it what should be the value of subdivision??
Thank you so much man🥺 god bless you
would really like to see you do this tutorial for a local machine using CPU or GPU options. Having trouble implementing on my local pc. Thanks.
This has to be the most thorough and effective step by step guide for yolo setup i have came across.
After training the model i'm looking at deploying it to a hardware device, any ideas? (I have a device that can run yolov3 models on it)
Thanks
You're a god, thank you so much!
Hey, you are awesome! One Question: Can you make a Video how to use Yolov4 with a webcam? Same Video like the Yolov3 one, just for Yolov4. I tried to transform the weights file of yolov4 with the same code of your yolov3 video into .tf but it run into some issues. As I expected it doesn't work. Thank you for sharing! :)
Will definitely cover a webcam video in the near future for YOLOv4! I'll let you know when it gets posted!
What if we wanted to just add 1 more class to the ones YOLOv4 can already detect? In particular I would like to detect both "people" and "faces" using the custom functions you made in a later video for detecting and cropping these 2 classes.
- What changes would I need to make to classes.txt, obj.data and obj.names?
- And to the variables __C.YOLO.CLASSES (coco.names) and __C.TRAIN.ANNOT_PATH (val2017.txt) of the config.py file of your custom functions?
I lack some experience in this field and I'm not sure whether I should retrain the whole model to detect these 2 classes from scratch or if I can just retrain the model so that it can learn to detect faces while still being able to detect people as it can by default. Love your content, the most helpful and practical I've seen :)
thank you. excellent work.
Thanks for the great yolov4 series!. I would like the ask if "chart.png" shows loss and accuracy on training data or validation data?
What changes are required if I want to train yolov3-tiny and yolov4 tiny?
You would want to edit yolov4-tiny.cfg inside the cfg/folder for the custom cfg. As well you will need to download the initial tiny weights for training instead of the .conv file used for full yolov4.
@@TheAIGuy can you provide the links for both yolov3-tiny and yolov4-tiny initial weights link from where I can download these weights. Thanks
Hello Sir, I have learnt use of YOLO by watching your videos. Thank you for providing such videos. Sir can you please provide us video on how to distinguish between static and moving object using YOLO in google colab?
AI Guy, Thanks for a nice tutorial brother ,this tutorial is supper amazing,through this tutorial I have done a lot of my pending projects .thank you so much brother .But would you please share with us on how we can determine the mAP OF YOLOV3 MODEL .
great tutorial.. thanks a lot
thanks for sharing, helped a lot
Very nice. It would be even nicer if you can show converting the model to tflite and using it in an Android studio project.
I have a question. I already follow your tutorial on building object tracking using yolov3 and it works. But how do I get some kind of result on the tracking in terms of value or graphs? I need to evaluate the tracker output. I hope you can help me with that. Thank you
thx bruh
Great Video! So in the future after I created the initial model, how would I be able to add more classes to the model?
Can we get a webcam tutorial? :)
Will be doing a YOLOv4 webcam tutorial shortly as multiple people are asking for it! Thanks for the suggestion. :)
@@TheAIGuy Nice! Thanks for sharing your knowledge.
amazinggg thank you so much
Thanks my man! Hope all is well with you.
Could you please do a video on how to use TPU for the same custom training?. Illustrating the changes required in code also.
Big Thanks Bro
Hi Bro, a cheers from HK! I hv followed every steps in yr tutorial, using a trained weight model (yolov3_8000) from others instead of yr pre-trained weights.
When I directly do Step 7: Run Custom Object Detector without train it on Colab, it shows "Unable to init server: Could not connect: Connection refused "
When I go to check the mAP of his model, it shows "Allocate additional workspace_size = 52.43 MB,
Loading weights from /.weights...Couldn't open file: /.weights ".
Can u advise how to solve this? Really really appreciate to u, bro!!!!
Thanks a lot !
I am having an issue, the generate_test.py and generate_train.py scripts are generating empty train and test.txt for me.
Let’s say yolo is detecting multiple objects of the same class, is there a way to conditionally stop detecting one of those objects?
yes check the *pyimagesearch* blog in which opencv has been used to read from the trained yolo model, subsequently taking the raw output and accepting only the detections related to some specific class.
Thanks for your Great support. !
My best wishes for your future videos. Your passion and energy is motivational for new learners.
Kindly help me that how can I amend this custom object detection for live streaming data from Cameras or Webcam. Kindly suggest way ahead. I tried but no affirmative results yet.
Hey sir thankyou for this amazing video, I wanted to ask you how can I get the confidence for each prediction?
hello, thank you for sharing, yr a lifesaver, wondering if I could just replace my trained weight directly to the yolo_webcam colab book you shared?
Thanks for this amazing tutorial. Much appreciated. I guess I have one comment though. When you train this model with new classes, it seems like it is actually losing all the original classes. I am assuming that was the intention all along? Doing a transfer learning on the core model with only the classes you would want to use.
Is it possible to actually add classes to the original list. That way we can still keep the original classes and improve the usability of the library. Thanks in advance.
Hey Rajesh,
I am also trying to find a way to do the same by adding new classes to the existing list of COCO. Did you find any approach that lets us do this?
thanks for this :)
How can we implement this on tensorflow and tensorflow lite ? Btw this is an amazing tutorial , truly practical and useful.
Immanuel Jzv Will be posting a video tomorrow that goes over implementing yolov4 with tensorflow and tflite!
Hi The AI Guy,
Great video! I have a couple of questions.
1. Is there a way I can save the chart.png that shows both avg loss and map, to my google drive?
2. My weights saved every 10k iterations instead of 1k iterations, where would I make this change to make sure that the weights are saved every 1k iterations instead of 10k iterations?
3. Any recommendations/suggestions to keep in mind for OCR using YOLOv4?
By any chance could you create a Google Colab for Yolo 9000? It allows there to be 9000 or more classes at a single time. This would be way more useful at classifying things with better name accuracy. For example I want to be able to know about different plants and politicians found in videos.
Thank's for a video, I want ask something , how to change conf_threshold and IoU_Threshold went I want to check my model mAP (step 6)?
Thanks for the tutorial. Can you please make a video on detecting customized objects on a video and webcam?
Sri Aditya B already have videos on this! Check them out.
@@TheAIGuy Just a small correction. I mean do you have videos on it using colab. It would be great if you can help me out here.
Sri Aditya B this video shows custom trained model and how to run on video.
@@TheAIGuy Thanks
Many thanks for a great video! I am training it on a small dataset of UAV images. I was wondering if you could suggest resources to understand more about your choice of model hyperparameters (the configuration file numbers) as per the equations, please?
Awesome tutorial! Thankful
btw, how to calculate the mAP in test dataset ?
Thank you!!
