mAP 0 for detr customized dataset

[fozzge]

I want to object detection using the detr algorithm with a fire dataset which received from roboflow. However, all results are always 0.
When I use the facebook/detr algorithm with the same hyperparameters, it does not return zero.
I want to use this package to be able to test other methods as well.
You can find the config file I used in this link [https://colab.research.google.com/drive/1T2Dfv4SnfAwjSUriVp-_ml_Kg-abhi8p?usp=share_link] What do I need to do to use my own dataset? Please help me.
