当我使用模型检查测试数据集上的 mAP 时,出现以下错误:
INFO:tensorflow:Restoring parameters from /home/aurora/workspaces/PycharmProjects/tensorflow/tensorflow_object_detection/outputs/model.ckpt-278075
INFO:tensorflow:Restoring parameters from /home/aurora/workspaces/PycharmProjects/tensorflow/tensorflow_object_detection/outputs/model.ckpt-278075

num_images_correctly_detected_per_class / num_gt_imgs_per_class)
我检查了 test.tfrecords,每个图像都有真实边界框。我该如何解决这个问题?谢谢。
