• export.py: The Python script responsible for handling the export process.

Exporting YOLO Models (NVIDIA and AMD GPUs)

Export to TensorRT Engine (For NVIDIA GPUs)

To export your YOLO model to a TensorRT engine (for NVIDIA GPUs only), use the following command:

python .\export.py --weights ./"your_model_path.pt" --include engine --half --imgsz 320 320 --device 0

• Replace "your_model_path" with the path to your YOLO .pt file.
• The --half flag enables half-precision inference for faster performance and lower memory usage.
• --imgsz 320 320 sets the image size to 320x320 pixels for export.
• --device 0 specifies the GPU device ID (use --device cpu for CPU-based inference).
• Note: TensorRT is only compatible with NVIDIA GPUs.

Export to ONNX

To export your YOLO model to ONNX format, use the following command:

python .\export.py --weights ./"your_model_path.pt" --include onnx --half --imgsz 320 320 --device 0

• Replace "your_model_path" with your YOLO .pt model.
• The --half flag enables half-precision inference (if supported).
• --imgsz 320 320 sets the image size to 320x320 pixels.

Export for AMD GPU

To export your YOLO model for an AMD GPU, use the following command:

python .\export.py --weights .\your_model_path.pt --include onnx --imgsz 320 320

• Replace "your_model_path" with the path to your YOLO .pt file.
• This command will export the model in the ONNX format for AMD GPU inference.

Troubleshooting

• If you encounter issues during export, ensure that your CUDA, cuDNN, and TensorRT versions are compatible with the version of PyTorch you are using.
• For ONNX export issues, ensure you have the correct ONNX version installed.

🚀 NVIDIA CUDA Installation Guide

1. Download the NVIDIA CUDA Toolkit 11.8

First, download the CUDA Toolkit 11.8 from the official NVIDIA website:

👉 Nvidia CUDA Toolkit 11.8 - DOWNLOAD HERE

2. Install the CUDA Toolkit

• After downloading, open the installer (.exe) and follow the instructions provided by the installer.
• Make sure to select the following components during installation:
  • CUDA Toolkit
  • CUDA Samples
  • CUDA Documentation (optional)

3. Verify the Installation

• After the installation completes, open the cmd.exe terminal and run the following command to ensure that CUDA has been installed correctly:

  nvcc --version
  

This will display the installed CUDA version.

4. Install Cupy

Run the following command in your terminal to install Cupy:

pip install cupy-cuda11x

5. CUDNN Installation 🧩

Download cuDNN (CUDA Deep Neural Network library) from the NVIDIA website:

👉 Download CUDNN. (Requires an NVIDIA account – it's free).

6. Unzip and Relocate 📁➡️

Open the .zip cuDNN file and move all the folders/files to the location where the CUDA Toolkit is installed on your machine, typically:

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8

7. Get TensorRT 8.6 GA 🔽

Download TensorRT 8.6 GA.

8. Unzip and Relocate 📁➡️

Open the .zip TensorRT file and move all the folders/files to the CUDA Toolkit folder, typically located at:

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8

9. Python TensorRT Installation 🎡

Once all the files are copied, run the following command to install TensorRT for Python:

pip install "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\python\tensorrt-8.6.1-cp311-none-win_amd64.whl"

🚨 Note: If this step doesn’t work, double-check that the .whl file matches your Python version (e.g., cp311 is for Python 3.11). Just locate the correct .whl file in the python folder and replace the path accordingly.

10. Set Your Environment Variables 🌎

Add the following paths to your environment variables:

• system varaibles
• edit PATH
• add NEW
• click okay

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\lib
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\libnvvp
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\bin

Setting Up CUDA 11.8 with cuDNN on Windows

Once you have CUDA 11.8 installed and cuDNN properly configured, you need to set up your environment via cmd.exe to ensure that the system uses the correct version of CUDA (especially if multiple CUDA versions are installed).

Steps to Set Up CUDA 11.8 Using cmd.exe

1. Set the CUDA Path in cmd.exe

You need to add the CUDA 11.8 binaries to the environment variables in the current cmd.exe session.

Open cmd.exe and run the following commands:

set PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\bin;%PATH%
set PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\libnvvp;%PATH%
set PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\extras\CUPTI\lib64;%PATH%

These commands add the CUDA 11.8 binary, lib, and CUPTI paths to your system's current session. Adjust the paths as necessary depending on your installation directory.

2. Verify the CUDA Version After setting the paths, you can verify that your system is using CUDA 11.8 by running:

nvcc --version

This should display the details of CUDA 11.8. If it shows a different version, check the paths and ensure the proper version is set.

3. Set the Environment Variables for a Persistent Session If you want to ensure CUDA 11.8 is used every time you open cmd.exe, you can add these paths to your system environment variables permanently:

4. Open Control Panel -> System -> Advanced System Settings. Click on Environment Variables. Under System variables, select Path and click Edit. Add the following entries at the top of the list:

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\bin
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\libnvvp
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\extras\CUPTI\lib64

This ensures that CUDA 11.8 is prioritized when running CUDA applications, even on systems with multiple CUDA versions.

4. Set CUDA Environment Variables for cuDNN If you're using cuDNN, ensure the cudnn64_8.dll is also in your system path:

set PATH=C:\tools\cuda\bin;%PATH%

This should properly set up CUDA 11.8 to be used for your projects via cmd.exe.

Additional Information

• Ensure that your GPU drivers are up to date.
• You can check CUDA compatibility with other software (e.g., PyTorch or TensorFlow) by referring to their documentation for specific versions supported by CUDA 11.8.

🚀 AMD GPU Setup Instructions (DirectML Support)

While NVIDIA GPUs utilize CUDA for deep learning, AMD GPUs can be leveraged on Windows using DirectML, a GPU-accelerated backend for machine learning.

1. Install PyTorch for AMD GPUs (DirectML)

For AMD GPUs on Windows, PyTorch supports DirectML as the backend. You can install PyTorch with DirectML using the following command:

pip install torch==2.5.1+cpu torchvision==0.20.1+cpu torchaudio==2.5.1+cpu --extra-index-url https://download.pytorch.org/whl/cpu

2. Install ONNX Runtime with DirectML

To use ONNX with AMD GPUs, install the onnxruntime-directml package:

pip install onnxruntime-directml

3. Verify AMD GPU Support

To ensure that your AMD GPU is properly set up, you can verify DirectML support by running the following script:

import onnxruntime as ort
print(ort.get_device())

If your setup is correct, this should return "DML", indicating that ONNX Runtime is using DirectML.
