Overview

Training is run on the WARG desktop on the Windows partition. A default Ultralytics model is loaded (e.g. nano) with no initial weights. Training configurations are described here: https://docs.ultralytics.com/usage/cfg/

Setup

Move or copy the 3 directories of the dataset so that it is in the dataset directory:

• C:\Users\WARG\Ultralytics\datasets\[test, train, val]

Make sure that any old datasets are out of this directory or have their test, train, val directories renamed (e.g. test_landing_pad, train-old, val0)! Hiding them in a directory underneath dataset is not sufficient (e.g. ...\datasets\landing_pad\test might still be erroneously used).

Activate the environment: Python Repository

Navigate into the training directory and run training:

cd training
python -m training

Training will take a few hours.

If training is interrupted, change the model load path:

• MODEL_RESUME_PATH = C:\Users\WARG\Ultralytics\runs\[latest training number]\last.pt

• data=MODEL_RESUME_PATH

Setup

Follow the instructions: Python Repository

Install packages: pip install -r training/requirements.txt

• Do not use the other requirements files

Navigate into the training directory and run training:

...

Follow the instructions to clone the repository and activate the environment: Autonomy Workflow Software

Install packages:

pip install -r requirements.txt

Run initial training to create the configuration files:

python -m training

If it reaches the dataset checking phase, press ctrl-c to stop the program. It will probably fail before that point with a file not found error.

...

datasets_dir: C:\Users\WARG\Ultralytics\datasets
weights_dir: C:\Users\WARG\Ultralytics\weights
runs_dir: C:\Users\WARG\Ultralytics\runs

Or more appropriate directories if desired.

Use other directories if desired.

Usage

Move or copy the 3 directories of the dataset so that it is in the dataset directory:

C:\Users\WARG\Ultralytics\datasets\[test, train, val]

Make sure that any old datasets are out of this directory or have their test, train, val directories renamed (e.g. test_landing_pad , train-old , val0 )! Hiding them in a directory underneath dataset is not sufficient (e.g. ...\datasets\landing_pad\test might still be erroneously used).

Navigate into the repository and activate the environment: Autonomy Workflow Software

Run training:

python -m training

Training will take a few hours.

If training is interrupted, change the model load path in training.py :

MODEL_RESUME_PATH = C:\Users\WARG\Ultralytics\runs\[latest training number]\last.pt

...

    model.train(
        data=MODEL_RESUME_PATH,
        ...,
    )

Where [latest training number] is the number of the checkpoint.

Hardware

Each epoch takes approximately 5 minutes to complete on an NVIDIA GeForce RTX 2060 with 6GB VRAM: https://www.techpowerup.com/gpu-specs/geforce-rtx-2060.c3310

• There is only enough VRAM for nano and small models, not larger ones.

• PyTorch version 2.4.1 is being used with CUDA 12.4, which has minimum driver requirements. Please ensure that a suitable driver is installed (there should be a high enough driver version for the RTX 2060, you can find them here if needed. (We are not going to use the old Jetson TX2i, but the RPi5 on the drone)
