YOLOv5 is the latest evolution in the YOLO family of object detection models. It's the first YOLO implementation native to 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.

Dude thanks for speaking in a way that teaches me instead of just assumes I already know this stuff
Certainly - thanks for tuning in.
Brilliantly done! You know how to keep the viewers glued to your video.
Great tutorial, maybe the best I have seen on Yolo. Thanks for sharing the Colab notebook
Best YOLO tutorial I've seen on UA-cam so far! Thank you!
Thanks so much!
I'm about to follow a yolo3 tutorial, and then I found the yolo4 tutorial, and then I found yolo5 tutorial, omg Thanks roboflow.
Thanks! Let us know what you want to see next.
this was the best video in the detection area by YOLO, believe me I tried a bunch of videos, non of them worked like this Thanks truly.
This worked GREAT for me! The best part was that it showed my training images and their labels, and it made me realize my training set was mis-labeled :)
Great to hear! If you're interested, we'd be happy to share your success on our blog. Write us in-app or here: docs.roboflow.ai/support
@@Roboflow Great, I just did!
Apart from the nits, noted below, THANKS for a great video, delivered in such an upbeat way!
Thanks for the feedback!
wow, great! thanks for sharing!
this video is so transparent and really easy to understand and follow
!!! awesome! going to test out now
I liked the shaving part and selfie part ..by the way ..this was so fun learning that hard skill in a funniest way..thankur so much sir..
Amazing work! Congrats! keep up
Hats off..what a teacher
Thank you! for the clear explanation :)
Great content! Thank you for this.
Best tutorial ever!! Thankss Joseph!! ;D
Thanks!
i love your facial expressions. thanks. i dont know anything yet but hopefully i am planning to go into this, this summer.
Thanks for your awesome sharing. Helps us a lot!
this guy is still a legend to this day
Amazing! Congratulations!!!
Thanks!
Thank you so much!
Great job 👏
amazing video !
He is funny af. And obvio the tutorial is awesome, thats very universal of him.
Sir you are amazing thanks, you make we want to get roboflow Pro! Keep it up!
Thanks a ton, I finished my project easily by referring this video
We love to hear that! What was the project that you worked on? :)

@@sainandhan1108 sweet! Is that something you can share? Seems very interesting
@Sai Nandhan. Bro koncham adhi ravadam ledhu bro, ninnu contact avacha?
Thanks Sir !
Hi Joseph .A great tutorial. The dataset you used was heavily unbalanced. The augmentation is performed on all images combined and not the ones that were misrepresented(WBC AND platelets).
Don't you thing that the trained model will be biased towards RBC?
Could you give some suggestions how to cope with unbalanced dataset?
or should I perform augmentation on the least represented classes?
thanks a lot!
This is a great video. I have a question, what if I want to use TensorFlow instead of PyTorch for YOLOv5 or 4?
Is it possible detect or recognize different person like different classes? Thanks great job!
perrrfectttt
how many trainable parameters does yolo5 have? does your training start with a pre trained model that used the coco dataset? if you use existing weights won't you need to re code the network head to change the classes to your own?
Hello, thanks for the amazing tutorial. I'm just wondering if we apply resizing for training data, but at inference, we use the original images. Does this have an impact on return?
according to glenn jocher, you should use the same size at inference, but i think you can use the resized size for both
Thank you Roboflow , thank you Joseph for this Excellent tutorial and colab notebook.
I want to create custom dataset for my final year project.
Can you please guide what should be image size and how to create dataset?
my dataset contains different types of invoices
Great video! Do you plan to upload video with opencv gpu c++ and yolov5?
Thanks for the video, would like to try this out since the previous model can’t really detect small objects.
My plan is to make an app to be able to detect ball and hoop and count field goal, so would like to ask is it possible to transfer all this into an app?
Thanks for making this video,Can you make a dataset on Garbage detection?
Its very nice. How can I download this model to my PC ? Is the weights are sufficient ?? I need the architecture also right ?? I want to make an android app for object detection , any tutorial available on that ? Pardon for any mistake in the question , I am a beginner.
Dude thanks this video was really helpful.
Just asking when i wanted to use roboflow to create my own data i didn't found the place where i have to use to generate data is it the new version that's why.
Btw thanks again.
Hi, thanks for the tutorial, actually I did the same steps and I used the model on a real-time video but I got only 4 FPS which is too slow , do you have an idea about that ?
Hey Nice video!
Is there a way to like export the weights and such to use in a custom python project?
I already trained a custom dataset, now I need to combine it with my python code that counts cars as they pass by.
There seems to be no videos explaining how to use yolov5 other than on google collab
Thank you very much for this great and detailed tutorial.
I would like to track the size and position of the object and use it in unity (like handtracking). Is there a tutorial or something alike for the next steps?
Thank you already for you help :)
can u explain what the meaning of "head", "backbone", and "anchors" on the models of yolov5?
First of all, really a great and fun video thanks for sharing. I was able to train with one of my custom datasets. Very simple and easy to use notebook too!!
I was just wondering what format of annotation does the Pytorch V5 model accept for bounding boxes? Is it still center coordinate, width and height?
The YOLO v5 PyTorch implementation uses .txt annotations in-line with the YOLO standard and adds a YAML config file to define train and valid.
@@Roboflow - Thankyou.
Thanks for your great videos. Please can you make a yolov5 tutorial on video stream with webcam and with an IP camera? Thank you very much:)
When I trained with the same, my model with the extension ".pt" is in compressed archive format, how do I get that back to a normal ".pt" file so that i can use it anywhere else? When I try to use the compressed archive directly, it gives an error of core dumped
Please tell me how these saved weights can be used for prediction
Roboflow is pretty awesome
Thank you!
Hey! One qus.
I have my own images and xml files given and downloaded in my pc.
How should I import those to collab?
with this method does the model is entirely learn end to end with our dataset or does it use pre-trained models with pre-configure weight ?
Also thank you for this clear tutorial
I believe that it is supposed to be training from scratch. He explains it on the moment 20:21, you can do both but the default is to train from null
Will *weights file* and *config file* generated by Roboflow be acceptable by "dnn" module of OpenCV ie: cv2.dnn.readNetFromDarknet ??
Thanks for sharing, como dijeran en mi México lindo, eres la v3rga!!!!
Many thanks for this 🙏
But how to deploy it to my own website?
i need a full explanation of tensor board measures and understand them please
Is it possible to just augment to the objects that yolov5 can detect already? Like for example I have a dataset of streetview images and I want to detect trees aside from cars and motorcycles. Do I have to retrain yolov5 again to detect cars and motorcycles, when it is already included in the original coco128.yaml file?
Great job there
I have only one question:
I need to convert the weight file to .onnx is there any tutorial that you would suggest or any script that I can add to colab and run it
Thanks.
Nice video !, roboflow has helped me a lot !!!
I'm new on Yolo and I have a question: The format of weights that is generated, is it useful to apply it in Tensorflow? or need a conversion?
TensorFlow requires TFRecords, which you can generate with Roboflow. We are not currently aware of a YOLOv5 implementation in TensorFlow.
@@Roboflow Is there a feature on the website to convert the .pt file into TFR?
@@JackJGX TFR? You can convert the PyTorch model to ONNX, and from ONNX there are ports to TensorFlow.
Hi, it is a great project. Can yolov5 work on mobile devices or run live webcam on google colab?
How can i use this saved weights for future prediction
Hi Joseph
Is it possible to save the trained model, instead of weights?
like TensorFlow "model.save" ??
Can you tell how to change the model architecture? Like the layers. I would appreciate that. If you have already made a made for that please leave a link to that. Thanks.
Hello sir, I have followed the same steps you have Given to train the model, but my MAP is decreasing per epoch. Please let me know how to solve this. Thanks in Advance
thank you for video and ı want to ask how can I find this trained model on mine local gpu on pycharm or jupyter
Does the test data also needs xml to be added with them ?
Hi, I'm working on a project and I need help with something. How do I find the correct epoch size for my project? Different tutorial videos on your channel have different epoch sizes. How do you determine this?
Good day!
We have some issues with object detection on custom datasets and would be appreciated any advice. Is it possible to have a 1-hours consultation?
thanks for the tutorial, but when i train my data it takes up to 5mins to complete one epochs on google colab, any help please ?
Dear sir.. where is the video you used in the lesson located sir?
Can you please tell me about how you labelled your dataset?
Thanks Roboflow and Joseph for wonderful tutorial, but im struggling to convert best.pt to .onnx file as all tutorials using .pth extension and torch.load() failing for .pt file, please help me on this
I have my own GPU i can train on, how would i go about doing that? don't want to use external websites with the datasets i have, as they are very limited.
I've been trying to use Yolov5 with PyTorch for the past few days... but there are some massive memory leaks during training. I'm constantly having to reboot.
How to change the bounding box thickness and label ?I mean if you have multible object you can't see the details in the img
great work! How can I use the trained weight file in a lambda function to detect new sample images, is there any resource to get a code?
have you found any way to deploy yolo model to lambda?
if yes please share with me also , I also want to deploy my yolo model to lambda funciton.
In very confused, once you mount the weights to your drive, how can you use it in your code????
Can i use this model for images prediction
Hi, Firstly so thanks for this video. I have a question. How I remove the test image rate? I don't want to look on rates.
Thanks! Visit app.roboflow.ai/account/upgrade to upgrade, or write us. Contact information is here: docs.roboflow.ai
I following all steps you provided, but there is no predictions on the test dataset. I don't know why!!!!
i have a json file and a zip file of yolo format. it contains txt files of all the images. which one should I use
Hey can any one say how to pass an image which in my desktop directory to detect and I have one class only
Thanks for making this video, helps a lot! If I wanted to train the model on the 2d object detection KITTI dataset, how can I get the annotations in the right format? Also, if the model expects the image to be square, does roboflow adjust the bounding box accordingly?
Have you struggled to upload your data? Write us an email (see our docs for how). We do support 2D object detection bounding boxes, like those found here in the YOLO format: github.com/keshik6/KITTI-2d-object-detection
Yes, Roboflow updates all bounding boxes correctly for any operation you perform.
Could you please share how to run yolov5 trained using python on iOS and Android using coreml or pytorch mobile?
I having issue with my dataset. my dataset is video based and it anootation file for bounding box is also given how can I convert it for yolo v5
min 18:20 is bit confusing, the command downloads the files into /content, but you open the /content/yolov5 folder? where do the files should go?
exactly did find the solution
When I run the program it cannot find the yaml file do you know what's going on?
Please upload video of auto annotation for custom dataset using roboflow
At 18:35
1) If we want to combine our custom set in default which yolov5 given sets
is it possible? and how
2) or can we delete some classes that we doesn't needs?
I would like to make custom sets with person classes,
But if I made custom sets in your videos' method
Maybe i think i have to make person dataset again .
( I'd like to add my customs to the existing default datasets. )
Can anyone guide me on how can I extract the predicted boundary box image and save that image in a folder? I used the same Yolo v5 custom dataset training strategy.
hi, may I ask how to use a "Try this model drop an image" box in a library that already exist? cuz when I drop the image it cant be detected an just shown this command
{
"predictions": []
}
@Roboflow "RuntimeError: non-positive stride is not supported" I get this error when I run the training command. My architecture is the same as the video. Does anyone else get this?
how could i run this in my Ubuntu Desktop? its just download all those files? and then witch .py should i run?
Should we use CUDA for training??
I am a student .. I have used free plan roboflow for annotating data.but I couldn't download the dataset .. Export was not there ..so what should I do
How do i test the model for a video? What should we change in the line 'detect.py'?
Note per the Ultralytics repo, when calling detect.py, source should be updated to "0" github.com/ultralytics/yolov5#inference
How do i convert the .pt file to .tflite? I have much difficulty doing that
I honestly don't understand why this model is working in Colab and does not working on my PC. It's always displaying nan loss. But pytorch setup is working well with other network architectures. What can be a problem with it?
thank you so much for all the help you giving
And can you please tell me how can I get .weights, .RT or even frozen graph from .pt file
Thanks! In the YOLOv5 notebook, your weights are saved to your Google Drive by default. You can download them from there. To export a PyTorch model to other formats, consider using ONNX: pytorch.org/tutorials/advanced/super_resolution_with_onnxruntime.html
@@Roboflow I appreciate the easy to use interface and notebook. Could you add some code to the end for converting the model to ONNX format? There is a file in the model directory called onnx_export.py, but I have been unable to get that to work.
@@tylersnard Appreciate the feedback. We'll be providing additional guidance on model export formats in coming content. (Note this is something we support for our Pro users by default, so if your workplace or project needs the support, we're happy to help. Contact via our site.)
Thanks for your video! Would you know how to convert the detect. py script to an .exe, please? Pyinstaller and cx_Freeze give errors.
