之前使用的数据格式是yolov5_obb的数据格式然后需要转数据格式
目前的数据只支持四个坐标点标注的数据参考If a corner of the rotate rectangle is out of the image range, How to annotate the image? · Issue #7581 · ultralytics/ultralytics · GitHub . YOLOv8 does not accept more than four points for a single objects annotation 数据格式转换为
label_index x0 y0 x1 y1 x2 y2 x3 y3
数据不完整怎样进行数据标注

1
subprocess.CalledProcessError: Command [/opt/conda/bin/python, -m, torch.distributed.launch, --nproc_per_node, 2, --master_port, 44569, /root/.config/Ultralytics/DDP/_temp_dutx5q5j140559331981920.py] returned non-zero exit status 1.
解决办法
终端输入
export MKL_THREADING_LAYERGNU
2
ModuleNotFoundError: No module named ultralytics
解决办法安装依赖库
pip install ultralytics
3
ile /opt/conda/lib/python3.8/importlib/__init__.py, line 127, in import_modulereturn _bootstrap._gcd_import(name[level:], package, level)
ImportError: libgthread-2.0.so.0: cannot open shared object file: No such file or directory
解决办法
apt-get install
apt-get install libglib2.0-dev
3.训练代码
from ultralytics import YOLO# Load a model
model YOLO(yolov8n-obb.yaml) # build a new model from YAML
model YOLO(./yolov8n-obb.pt)
# results model.train(datacarddet.yaml, epochs100, imgsz640)
results model.train(datacarddet.yaml, epochs400, imgsz640)
