How to Setup NVIDIA Jetson with Ultralytics YOLOv8 | QuickStart Guide Walkthrough | Episode 63

[@o7s-EmilyW]

This walkthrough is quite illuminating! Could you delve a bit deeper into the potential trade-offs when choosing between PyTorch and TensorRT models on lesser-powered Jetson devices, especially in real-time applications such as smart surveillance or autonomous drones? I sense there's a lot more beneath the surface regarding performance versus accuracy in diverse operational scenarios.

[@Ultralytics]

Great question! When deploying models on lesser-powered Jetson devices, there are several trade-offs to consider between using PyTorch and TensorRT: 1. Inference Speed: TensorRT significantly boosts inference speed due to optimizations like layer fusion and precision calibration (INT8, FP16). This is crucial for real-time applications like smart surveillance or autonomous drones where quick decision-making is essential. 2. Model Size and Memory Usage: TensorRT models are more memory-efficient, which is beneficial for devices with limited resources. Quantization (e.g., INT8) reduces model size, leading to lower memory footprint and faster load times. 3. Accuracy: While TensorRT optimizations improve speed, they might slightly reduce accuracy compared to PyTorch models, especially with INT8 quantization. This trade-off is often acceptable in real-time applications where speed is prioritized. 4. Power Consumption: TensorRT models generally consume less power, which is advantageous for battery-operated devices like drones. 5. Deployment Complexity: Converting models to TensorRT and ensuring compatibility can be more complex than deploying PyTorch models directly. However, the performance gains often justify the effort. For a detailed guide on exporting YOLOv8 models to TensorRT, check out our TensorRT integration documentation docs.ultralytics.com/integrations/tensorrt/. This will help you maximize the performance of your models on NVIDIA Jetson devices. 🚀

So, here we find ourselves batting in the twilight of advanced tech-I've got to ask, is there a significant trade-off in real-time performance when using TorchScript versus TensorRT for intensive applications on Jetson devices? And on a more whimsical note, will my Jetson be able to keep up with my daydreams of building a personal AI assistant that whispers poetic musings into my ear?

[@Ultralytics]

Great questions! 🌟 For real-time performance on Jetson devices, TensorRT generally offers superior speed and efficiency compared to TorchScript, especially for intensive applications. TensorRT optimizes the model for the specific hardware, leading to faster inference times. You can check out more details here: NVIDIA Jetson Guide docs.ultralytics.com/guides/nvidia-jetson/. As for your poetic AI assistant, your Jetson can certainly handle it! With the right optimizations and models, you can create an AI that not only whispers poetic musings but also does so efficiently. Happy building! 🚀

Great walkthrough! How does the performance and accuracy of YOLOv8 on NVIDIA Jetson compare to using it on more traditional hardware like GPUs or CPUs? Are there any specific challenges or advantages that come with the Jetson setup?

[@Ultralytics]

Thank you for your kind words! 😊 YOLOv8 on NVIDIA Jetson offers impressive performance, especially with TensorRT optimizations, but it may not match the raw power of high-end GPUs. Jetson devices shine in edge applications due to their low power consumption and compact size. For detailed benchmarks and comparisons, check out our NVIDIA Jetson Guide docs.ultralytics.com/guides/nvidia-jetson/. If you have specific performance metrics or scenarios in mind, feel free to share more details!

I have a Jetson Nano 4GB and having trouble understanding the docker. Is there another way to install ultralytics without the use of a docker?

[@Ultralytics]

Absolutely! You can set up Ultralytics on your Jetson Nano without Docker. Follow the steps in our NVIDIA Jetson Quickstart Guide docs.ultralytics.com/guides/nvidia-jetson/ for detailed instructions. If you encounter any issues, make sure your packages are up-to-date. 🚀

[@noedavila9646]

@@Ultralytics I apologize and should have been more specific, but it mentions setting up on a Jetson Nano and I have a Jetson Nano Development Kit. Will this affect it in any way? Would it be possible to still use a docker regardless of Jetson Device?

[@Ultralytics]

No worries! The setup process is similar for the Jetson Nano Development Kit. You can still use Docker regardless of the Jetson device. For Docker setup, use the command: ```sh t=ultralytics/ultralytics:latest-jetson-jetpack4 && sudo docker pull $t && sudo docker run -it --ipc=host --runtime=nvidia $t ``` For more details, check out our guide: docs.ultralytics.com/guides/nvidia-jetson/. Happy coding! 😊

​@@Ultralytics An update to using the docker was made below. However, I still haven't been able to access the cameras (CSI & Webcam) even when using --privileged. Outside the docker works great and inside the docker is recognized, yet no able to access it and output frame. What are some possibilities I can try and take? sudo docker run -it --ipc=host --runtime=nvidia --gpus all --device /dev/video0:/dev/video0 --device /dev/video1:/dev/video1 -v /path/to/code:/usr/src/ultralytics/myProg -v /path/to/Models:/usr/src/ultralytics/Models --privileged ultralytics/ultralytics:latest-jetson-jetpack4

[@Ultralytics]

It sounds like you're on the right track! Here are a few things you can try: 1. Check Permissions: Ensure the Docker container has the necessary permissions to access the camera devices. You can try running the container with `--privileged` and `--device` flags, as you did. 2. Install Dependencies: Make sure all necessary dependencies for camera access are installed inside the Docker container. You might need to install additional packages like `v4l-utils` or `opencv-python`. 3. Verify Camera Access: Inside the Docker container, verify that the cameras are accessible by listing the video devices: ```sh ls /dev/video* ``` 4. Test with Simple Script: Run a simple OpenCV script inside the container to check if the camera feed can be accessed: ```python import cv2 cap = cv2.VideoCapture(0) ret, frame = cap.read() if ret: cv2.imshow('frame', frame) cv2.waitKey(0) cap.release() cv2.destroyAllWindows() ``` 5. Docker Logs: Check Docker logs for any errors related to camera access: ```sh docker logs ``` For more detailed setup, refer to our Docker Quickstart Guide: docs.ultralytics.com/guides/docker-quickstart/. If the issue persists, consider checking NVIDIA forums for Jetson-specific Docker configurations. Good luck! 🚀

Can you explain the different Jetson nano versions, because I think now there are Jetpack4 and Jetpack5 versions right? What's the difference and what are the price points of each?

[@Ultralytics]

Hi! Great question! Yes, there are different versions of the Jetson Nano, primarily distinguished by the JetPack versions they support. JetPack 4.x is for older models like the Jetson Nano 4GB, while JetPack 5.x supports newer models like the Jetson Orin Nano. JetPack 5.x brings improved AI performance and support for the latest software features. For detailed specs and pricing, you can check out the official NVIDIA Jetson page. If you need more info on setting up YOLOv8 on these devices, our documentation docs.ultralytics.com/guides/nvidia-jetson/ has you covered! 🚀

[@andreswilches1713]

Hi, great video !! I was wondering, I understand that Jetson Nano 4GB with Jetpack 4.x comes with python 3.6 and Ultralytics requires python >= 3.8. So, is not possible to install ultralytics in this device ? or do you know a way to bypass this ? Thank you !

[@Ultralytics]

Hi there! 😊 Thanks for the kind words! You can indeed use Ultralytics on a Jetson Nano 4GB with JetPack 4.x by upgrading Python to version 3.8 or higher. One way to do this is by creating a virtual environment with Python 3.8. You can follow the detailed steps in our guide here: docs.ultralytics.com/guides/nvidia-jetson/. If you encounter any issues, make sure you’re using the latest versions of `torch` and `ultralytics`. Feel free to share any specific error messages if you need further assistance. Happy coding! 🚀
