YOLOv5 is the latest version of YOLO family of object detection models. It's the first YOLO implementation in PyTorch (rather than Darknet) and emphasizes ease of use and quickness of training and inference. This YOLOv5 tutorial shows you how to train the model on your own dataset in Python and how to test your Model.
What is YOLO?
YOLO stands for You Only Look Once
YOLO is an algorithm that uses neural networks to provide real-time object detection. This algorithm is popular because of its speed and accuracy. It has been used in various applications to detect traffic signals, people, parking meters, and animals.
With the timeline, it has become faster and better, with its versions named as:
YOLO V1
YOLO V2
YOLO V3
YOLO V4
YOLO V5
YOLO V2 is better than V1 in terms of accuracy and speed.
YOLO V3 is not faster than V2 but is more accurate than V2 and so on.
How the YOLO algorithm works?
YOLO algorithm works using the following three techniques:
1- Residual blocks: image is divided into various grids. Each grid has a dimension of n X n
2- Bounding box regression
3- Intersection Over Union (IOU) : YOLO uses IOU to provide an output box that surrounds the objects perfectly.

Thank you so much for amazing and very clear tutorials. You explain things very well. I love your videos. Are you going to do a video/playlist on YOLOR anytime soon?
Yes, soon
Thanks Ms. Aarohi, you're a superstar. Thanks for this video, came in super handy during a very crunch project! :))
Glad it was helpful!
Thanks for the great tutorial but there are slight rectification needed. Weights file are not downloaded by default. It is created when you do training. Only after training you will be able to see the weights file.
It was so clear, thank you so much. I am going to learn more from your videos.
Wonderful! Keep Learning 🙂
Mam, The graphs we have are Precision, Recall, mAP. How do we find out the accuracy of the model?
I became your fan mam...you're education really helping 1000s of students to learn state of art algorithms and their practical uses. How to create custom dataset for Yolo ?
Put all the images in folder and then Use labelImg tool. You can download it from github.
Nice video, it's quite a bit easier than getting yolo_v4 to run. Thank you.
yeah
Very precise explanation. Many thanks :)
Glad it was helpful!
thankyou madam that was useful. i trained using my own dataset but no matter how long i trained it the m@p will not get improved from 0.34 something like that i have used same data for yolov4 but it performs well
Great way of explanation!!
Keep going
Thank you, keep Watching
Your Video Helps alot ! Thank You Very Much !
Glad it helped!
Very excellent explanation! Thanks a lot.

Glad it helped
Really helpful, it would be awesome if you teach how to use Detectron2 as well, thx a lot
Noted! Will do soon
This is very helpful thank you really
Glad it was helpful
Clear steps and perfect video in youtube, thank you very much ma'am. I have one thing I need you to clarify.. what is the format of images that must entered to yolov4 and yolov5? I have a dataset with bmp files and in grayscale mode with varient size. Do I need to convert the images before enter them to yolo? Please help
I am not sure about bmp images but I use jpg format in yolo. I think you need to convert the images into jpg format.
Very helpful video.
Glad it was helpful!
Awesome content, was very useful in my job!)
But there is one question: when you tested the trained neural network on a single photo, the result was only a picture with highlighted areas.
How can I get the coordinates of the corners of the selected area?
use python to that for you
img = cv2.imread(image_path)
# convert the image to grayscale
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
# apply thresholding on the gray image to create a binary image
ret,thresh = cv2.threshold(gray,127,255,0)
# find the contours
contours, _ = cv2.findContours(thresh,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)
# take the first contour
cnt = contours[0]
# compute the bounding rectangle of the contour
x,y,w,h = cv2.boundingRect(cnt)
print(x,y,w,h)
Mam, if i want to count the number of sign board in the test image means what should i do?
good job
Thanks
thank you ma'am
Most welcome 😊
Extreamly nice thank you it was verry helpful pleas can you show as how we can use our custom dataset
Glad you liked my video. And you can follow this video ua-cam.com/video/yGMZOD44GrI/v-deo.html to prepare your custom dataset in the format of yolo And then you can apply yolov5 algorithm on it.

i did everything correctly according to this tutorial.
i will be very thankfull to you if guide me to this error..
Thanks!
Welcome!
i followed your tutorial step by step and i loved it but while training the module, when i enter that command to train, it is asking me to configure clear-ml and giving a comet warning and i am not getting a detect folder, can you please help me resolve the issue, if you want me to send you code i'll do so.
thank you so much
Amazing video. thank you very much. can you make video on vehicle detection and counting using camera captured video please shared video on this.
I will cover the requested topic after finishing my pipelined work
how do i Enable GPU Training on RTX series? any idea? havent found anything CUDn compatible!
Can you please put a detailed implementation of yolo v5 with tracking ? It will be really helpful :)
Sure
20:50 When I gave this command, my image didn't detect anything like I trained. It said no detections in the output. What can I do to the command to make it detect?
Hi mam, I wanted to apply optical flow estimation inside the detected bounding box from YOLOv5, can you please help me
Will you please provide this dataset link which you used to make prediction in your video ? By the way thank you so much for a great video about Yolov5 and there are some information missing for us like if I want to use to train the model for image resolution with 1024*1024. Then which weight I have to used to accomplish this task. Your view/help regarding this will be priceless.
Thank you for the feedback. Will try to cover such things in my upcoming videos. This dataset is available on kaggle.
Hi Ma'am how can I measure distance from camera after detecting traffic sign.
How to prepare those dataset? I have only test, train and train_label dataset.
that was very interesting.my question is yolov5 uses image label format same with yolov4 right? and how can i use this model if i wanted to webcam ?

@@dishabhatti6456 Glad to know that my video helped you
I love you
Have approximately 65 images which has approximately 10 unique sub objects within each train image currently I am working on 4 labels with epoch of 60 and batch of 16 but it's able to detect only one object even if i use train data set. Is it bcoz my number of images are too less or my epoch and batch numbers have some issue? As same trained dataset worked perfectly fine in yolov4 darknet with 80-95% accuracy .
As you are saying you were getting good results in yolov4 with same amount of images then I think you should increase the number of epochs.
I'm trying to follow the video but I keep getting AttributeError: module 'tensorflow' has no attribute 'io', do you now what should I do?
Mam, I have a query. Let's suppose I trained a model for 50 epochs and I want to continue the training from the 51st epoch. So how to save checkpoints and start to train the model from 51st epoch?
mcp_save = ModelCheckpoint('best_model.h5', save_best_only=True, monitor='val_accuracy')
model_final.fit(train_x, train_y, validation_data=(test_x, test_y), epochs=50, batch_size=8, verbose=1, callbacks=[mcp_save])
@@CodeWithAarohi Thank you Mam. A follow up question. I got FP as 1 in the confusion matrix and mAP for all IOU from 0.5 to 0.95 is around 0.65. Please suggest me how to improve these results. And also if freezing and unfreezing can be done to improve these results.
I don't know how but my training ran for 100 min for the first time and stopped and now it only runs for 5 sec. What to do?
Hello ma'am can you please tell me how to find accuracy of the model???
Mam, How to import all images from the test or val dataset and calculate the average time taken (inference time) by the model to detect the objects in one image?
I have trained and predicted and everything works fine and I saved best.pt weights file to drive and tested again after few days its says requirment.txt not satified ? Again should i train ?
Check if the requirement.txt file is there. IF it is there then check if everything from requirement.txt file is installed at your new location.
Please, I have a problem: when I used cv2.dnn.readNetFromTensorflow I need a weight file (.pb) which I've got but it need also a configuration file (.pbtxt) so how can I get a (.pbtxt file). Thanks a lot.
To use the cv2.dnn.readNetFromTensorflow method in OpenCV, you will need to provide both a weight file (.pb) and a configuration file (.pbtxt). The weight file contains the trained weights of the model, and the configuration file defines the network architecture and other details of the model.
If you only have the weight file and not the configuration file, you will need to recreate the configuration file in order to use the model with OpenCV. This can be done by using the TensorFlow framework to extract the network architecture and other details from the weight file. Here is an example of how to do this using TensorFlow 2.x:
Copy code
import tensorflow as tf
# Load the weight file using the TensorFlow Keras API
model = tf.keras.models.load_model("my_model.pb")
# Save the model architecture to a .pbtxt file
with open("my_model.pbtxt", "w") as f:
f.write(model.to_json())
This code will load the weight file using the TensorFlow Keras API, and then save the model architecture to a .pbtxt file. You can then use this .pbtxt file together with the weight file when calling cv2.dnn.readNetFromTensorflow.
I hope this helps!
@@CodeWithAarohi OK understood. Thanks a lot for your kind generous reply. I really appreciate your help.
it's giving me an error saying module "models" not found, even though I'm trying to install it isn't getting installed
i do my research using yolov5, but i dont understand how to modify the backbone or changing attention module. can you please put a detailed implementation different backbone on yolov5 like using resnet, mobilenet or vgg to yolov5???
Will try to cover that but after finishing my pipelined tasks.
Ma'am , I have a dataset which have been labeled with two classes on each image. I need to detect both classes on the test image. So will your code work the same for my purpose? Or do I have to change it?
Yes this code will work. You have to make few changes like the name of classes and number of classes. After watching the video, you will know where to make changes.
@@CodeWithAarohi Thank you ma'am. It seems like YoloV5 implementation is far easier than YoloV4.
I do have another doubt. I also want to implement Yolov4 with my dataset. Would it work properly if I annotate each image with instances of both classes and keep both the image file and annotation text files in a single folder? Or do I have to create separate folders for each class?
Hello, does including negative photos to my dataset improve the detection of custom object?
If your dataset have class Imbalance problem then try to solve it. Try to have equal number of positive and negative photos
I was trying the same model for my dataset. But while training its giving me error saying dataset no found,nonexistent paths. Some please help me with this. Thankyou
Same here☹️
Hi, the Yolov5 confusion matrix does not match the precision and recall rate
Output is not stored in the weights folder mam can you give solution?
I am doing it but it is not creating any weights. Neither best.pt nor last.pt
Ma'am, why didn't you create 'test' folder?
Thanks for the video mam . I have trained a model on colab. Can you please tell me how i can save the model and use it in some other project.
The model saving process is same as we save on our local computer
I am wondering if I would like to use a test set and see the accuracy of using that. How should I do it?
Yes, ViT can be applied to video datasets. While ViT was initially designed for processing static images, researchers have extended its application to video data by incorporating temporal information.
hi, mam, i have trained the model, but if i test an image(.jpg), then a blank folder (exp) is created inside detect like detect\exp , thus it throws file (best.pt) not found error although i have it. thanks a lot.
I have the same issue were you able to find the reason?

It means that the train.py file is not present at that location.
Can you tell me how to get the annotate file and text file of a dataset in Roboflow?
Sure, here are the steps to get the annotation file and text file of a dataset in Roboflow:
Open the Roboflow platform and sign in to your account.
Click on the "Datasets" tab in the top navigation menu.
Select the dataset you want to work with from the list of datasets.
In the dataset view, you will see several tabs such as "Images," "Classes," "Annotations," etc. Click on the "Annotations" tab.
You will see a table that lists all the annotations for the images in your dataset. To download the annotation file, click on the "Download" button in the top right corner of the table and select the desired file format.
To download the text file that contains the image paths and their corresponding annotations, click on the "Export" button in the top right corner of the dataset view and select the "CSV" option.
In the CSV export dialog, select the columns you want to include in the text file (e.g., "image path," "class name," "bounding box coordinates," etc.) and click on the "Export" button.
Your text file will be generated and you can download it by clicking on the "Download" button.
That's it! You should now have the annotation file and text file for your dataset in Roboflow.
In training process we only give images path ...and also we give images path in .YAML file ...so my query is why we create labels if our model is not using that labels?????
Both the input data (images) and the labels are crucial. The reason you provide image paths in the YAML file is so that the training script knows where to find the images. However, alongside these images, the corresponding labels are also expected to be in a specific format and location, typically in the same directory structure as the images.
@@CodeWithAarohi ohkkk....thank you so much 👍
Yolov5 folder does not have run folder and yolov5s.pt file .how should we proceed further.help us to resolve this problem mam!
You need to download the yolov5s.pt from official YOLOv5 github repo. And runs folder will get created when you start the training.
can we use pascal voc dataset in xml formate without changing it to text file formate
Your data should be in the format which yolov5 accepts
Great video mam . I have one issue in yolo v4 that if my image shape is 4000x3000 then in config file what will be the height and weight values?
Whatever height and width of images you have in your dataset. Yolo will resize it to the height and width which you define in cfg file. For eg: If your height and width is 416 in your config file then your dataset images will get resized to this size.
@@CodeWithAarohi mam will it affect the prediction if my dataset shape is high and yolo resize it to lower shape ?

HOW ADD TWO MODEL INTO ONEMODEL
Hello,
Can you explain us how we can retrain our model in order to obtain better results?
Collecting more data: One of the main reasons for a model to underperform is a lack of sufficient data to train on. Preprocessing the data: The quality of the data you use to train your model is very important.
Tuning hyperparameters: Hyperparameters are settings that can be adjusted to optimize the performance of your model. Tuning hyperparameters can help you find the best combination of settings for your model.
