RecursionError: maximum recursion depth exceeded when merging DeepLabV3 config - machine-learning

Question

I want to train semantic segmentation to recognize small objects. For this I use DeepLabVabV3. But when installing the config, I get a recursion error that reloads the environment. Am I setting the config correctly or is there a problem in my yaml file?
cfg = get_cfg()
cfg.load_yaml_with_base('/content/Base3-DeepLabV3-OS16-Semantic.yaml')
cfg.MODEL.WEIGHTS = '/content/model_final_0dff1b.pkl'`
