@dirtishurt hello! It sounds like you're encountering an issue where your application freezes during training. This typically happens due to the heavy computation involved in training models, which can block the main thread of your PySide6 application.
To tackle this, running the training in a separate process can help. Although you've mentioned attempts with multiprocessing, I recommend specifically using Python's multiprocessing.Process
to execute the training. Here is a concise example:
from multiprocessing import Process
from ultralytics import YOLO
def train_model():
model = YOLO('yolov8n.pt')
model.train(data='coco128.yaml', epochs=100, imgsz=640)
# Run the training in a separate process
if __name__ == '__main__':
p = Process(target=train_model)
p.start()
p.join()
Ensure this code block runs under the if __name__ == '__main__':
condition, especially important on Windows, to avoid recursive subprocess spawning.
This setup should prevent your GUI from freezing. Let me know if this helps or if further assistance is needed! 🚀

I got it working with a QThread() and I'm leaving this comment here if anyone has a similar issue in the future.
from PySide6.QtCore import QThread
from ultralytics import YOLO
class workerThread(QThread):
def __init__(self, parent):
super().__init__()
self.parent = parent
self.e = 0
self.model = YOLO(self.parent.model.path)
def run(self):
e = 0
if os.path.exists(os.path.join(self.parent.workingDirectory, 'runs')):
pass
else:
os.mkdir(os.path.join(self.parent.workingDirectory, 'runs'))
export_path = os.path.join(self.parent.workingDirectory, 'runs')
if torch.cuda.is_available():
print('CUDA Compatible Detected, Starting Training')
self.model.train(data=self.parent.dataset.path, device=0, patience=self.parent.patience,
epochs=self.parent.epochs,
imgsz=640, project=export_path, verbose=False)
else:
print('WARNING CUDA COMPATIBLE GPU NOT DETECTED, TRAINING WILL TAKE LONGER...')
self.model.train(data=self.parent.dataset.path, device='cpu', patience=self.parent.patience,
epochs=self.parent.epochs,
imgsz=640, project=export_path, verbose=False)

@dirtishurt that's great news! 🎉 Thanks for sharing your solution using QThread
with the community. It's super helpful for others who might face the same issue and are looking for a proven workaround. Your example is clear and effectively demonstrates how to integrate YOLO training into a PySide6 application without freezing the UI. Great job, and thanks again for contributing! 👍
