Hi @Taha_Er
I know nothing of all this to be honest. But looking quickly around:
Can you please try out : exp_config = exp_factory.get_exp_config('maskrcnn_spinenet_coco')
And I assume you have to adjust model parameters/settings thereafter in the notebook.
Please find the different experiments supported here from official model garden. Once you load you change backbone and heads based on your requirements. Hope this helped.
