Wow what a milestone! Thanks for watching. Never thought this was a possibility when I made the video

[@starioa]

How did you know that the "zero" in model.predict( source = 0 is the webcam. I want to send live camera content from an android app to the windows machine then do Real-Time Object Detection with YOLOv8 and then in the phone screen to print labels with the prediction just like 11:35 in your video. How could I do that? Thanks

[@emiralkan6016]

source = 0 is most of the time is the inbuilt webcam by default. About other question no idea sorry

[@adekojoadeyemi2596]

Is it possible to use different custom trained models in a single project with webcam. I trained a model with ASL alphabet and another models with ASL action, how can I join both models together on my live webcam project so that it can detect both alphabet and action. I am using ultralytics python library.

[@fishfooties9850]

hey may i know about your asl action? im currently working on a tennis gesture program for my highschool project.

[@fahadzhossain]

Hi. this video is great. I have trained a model. I installed ultralytics using pip but when I run the code in visual studio for prediction it is showing "from ultralytics.yolo.v8.detect.predict import DetectionPredictor ModuleNotFoundError: No module named 'ultralytics.yolo' " Please help me with this

[@supapholkodtom517]

Maybe have use with miniconda3 and create virtual environment(option)

[@GraTen]

Had the same issue, and found out you don't need the line completely, so just delete it or comment it out and you'll be good.

[@tinycat5349]

dude thanks this brought my dog back

[@nochance7167]

Hello, Nicolai! Very good video. How can I count and memorise in a variable the objects that the model detects and display the maximum number of the objects from a class into the console? Thank you!

[@NicolaiAI]

You will need to run object tracking on top of that! Thanks a lot for watching

[@StaMariaRock]

Nice video, I'm struggling like hell to install this yolo in anaconda with GPU, I'm following all the steps but is running on CPU, can you do a video about it? I'm trying to train a model, but the torch is picking my CPU

[@NicolaiAI]

I’d just uninstall torch, torch vision and install the gpu version

[@StaMariaRock]

@@NicolaiAI yeah! you were right, I uninstall torch and torchvision, reinstalled with the pip (the conda seems like is not working well) and after it I run conda update --all and done, is working now Amazing advice! thanks so much

[@fedorlaputin9119]

Where can I see the full yolov8 architecture for object detection?

[@maiquelkappel7745]

Congratulations on the job. Can you make a video of yolov8, mss and numpay, capturing the image directly from the monitor screen?

[@BimaAgungSaputra-gt4px]

hi! good tutorials btw. im new using yolo model, when i run your code in my machine it said "import ultralytucs.yolo.v8.detect.predict could not be resolved". am i missing a step here? because i already installed ultralytics and opencv libraries, or maybe i have to install another libraries? thanks in advance

[@AI_mod]

try from ultralytics.models.yolo.detect import DetectionPredictor

[@benjaminlines6387]

Do you still have to install CUDA on your machine? Because somewhere I read that torch comes with its own toolkit. I kinda don't want to mess up my other projects, that are using CUDA 10.0

[@NicolaiAI]

U Can install it directly with pytorch. Think u Can use 10 as well

[@FBal28]

Just wanted to mention I had to change print(results) to print(*results) to make this work. otherwise it just took a single picture and quit. Also, what specs are you running on? I'm getting around 80ms per frame

[@NicolaiAI]

Thanks for the tip! Im running on a Rtx 4090. Make sure u are on gpu if u have that

[@FBal28]

​@@NicolaiAI Yep, looks adding device='mpu' as an argument to model.predict is needed for mac users. Unfortunately, they haven't finished adding support for it, so mac users are stuck with cpu for now

[@Cam022]

So I don’t need to worry about open cv from source for GPU support for this? Just need the PyTorch with GPU support?

I want to classify different classes like types of cars model how can i achieved it?

[@badaldesai3743]

Can we detect distance between two different classes using Yolo v8. I mean (dist. btw a human and chair) ?

[@NicolaiAI]

Only relative distance in the frame ynkes u have 3D information

U Can check for key presses with opencv as I do in the bottom of the while loop. Then u will terminate and release resources

how do you change the size, there are different webcams and with different resolutions, not all of them are 640. Like when an .mp4 video is processed?

[@NicolaiAI]

I think u can specify it as an argument. But it also preprocesses the image before hand and resizes the images

Did you figure out how to do it? I also need to extract license plate numbers in real-time using easyOCR. I’d appreciate any help.

[@benjaminlines6387]

In the results... should be a tensor, right? Because in older versions you could do: results = model("image.png") And in the results would be your bounding box data. Now it tells me that there are 2 persons and 1 tie in that image (and it's also correctly saved in predict folder) but if im trying to print the result it prints none. Is there some extra method of getting results? Not working with camera right now, just an static image.

Hey ! I have used yolo v8 with my rtx 3050 and I am getting good training and predictions on the coco128 dataset BUT the problem arises when I try to use a custom dataset, the training goes well, but when I see predictions it just gives the same image with no bounding boxes. The labels are correctly placed because it gives the bounding boxes for the already defined labels, but not any for predicted ones . Any solutions ?

Would this software be able to track an object in 3d space? Say if you had an AR/VR environment and you wanted to track the position of objects in the room that might get moved around?
