Where to find eval_with_plac() function?

[Testbild]

Hi, in the test_hrsc2016.py there is the following function:

eval_with_plac()

class TestHRSC2016RetinaNet(TestHRSC2016):

    def eval(self):
        retinanet = build_whole_network.DetectionNetworkRetinaNet(cfgs=self.cfgs,
                                                                  is_training=False)

        all_boxes_r = self.eval_with_plac(img_dir=self.args.img_dir, det_net=retinanet,
                                          image_ext=self.args.image_ext)
...

I struggle to find, where the function is defined, so I can see what it does. Could you tell me where I have to look?

Thank you very much and best regards!
