hard_example转换问题 #9

Open djjandXMU opened 5 years ago

djjandXMU commented 5 years ago

请问楼主，你在util函数中，convert_to_square子函数转换为更大正方形极有可能超出图像索引，请问这样是否正确？

LeslieZhoa commented 5 years ago

Hi @djjandXMU 确实会有可能超出， https://github.com/LeslieZhoa/tensorflow-MTCNN/blob/d017494a63955cd68887f1d48e245ef78d6ff488/preprocess/gen_hard_example.py#L130 此处会去除掉超出的框

你好！@djjandXMU问一下hard_example训练o_net网络时有没有出现以下报错？麻烦解答一下，谢谢。 lunar@lunar-virtual-machine:~/PycharmProjects/tensorflow_mtcnn/preprocess$ python gen_hard_example.py 24 2019-05-12 09:33:06.690596: I tensorflow/core/platform/cpu_feature_guard.cc:140] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA 载入数据 8247it [2:47:10, 1.26it/s]Traceback (most recent call last): File "gen_hard_example.py", line 193, in main(parse_arguments(sys.argv[1:])) File "gen_hardexample.py", line 70, in main detectors,=mtcnn_detector.detect_face(test_data) File "../detection/MtcnnDetector.py", line 87, in detect_face boxes, boxes_c, landmark = self.detect_rnet(im, boxes_c) File "../detection/MtcnnDetector.py", line 181, in detect_rnet clsscores, reg, = self.rnet_detector.predict(cropped_ims) File "../detection/detector.py", line 63, in predict return np.concatenate(cls_prob_list, axis=0), np.concatenate(bbox_pred_list, axis=0), np.concatenate(landmark_pred_list, axis=0) ValueError: need at least one array to concatenate

你好，我没有出现这个问题。我是在ubuntu上运行的。直接在命令行输入作者给的代码即可

谢谢啦！我是在Ubuntu下pycharm环境下用命令运行的，p_net、r_net都可以正常生成数据

我也遇到了同样的问题，请问您解决了吗？

djjandXMU commented 4 years ago

直接用即可，代码没有出错。

我也遇到同样的问题了，请问具体怎么解决的？

djjandXMU commented 4 years ago

没有问题，虽然是负的，最后通过max(x,0)操作就会归于零，注意看代码后面部分

调试代码之后发现， num_boxes=np.sum(np.where((np.minimum(tmpw,tmph)>=delete_size),ones,zeros))这里返回的num_boxes为0，所以产生了上述错误。

这个感觉应该是好多在win10上跑的小伙伴才会有的问题吧，可以在添加在MtcnnDetector.py的detect_rnet(self,im,dets)里面，修改如下：

在上述代码（num_boxes=np.sum(np.where((np.minimum(tmpw,tmph)>=delete_size),ones,zeros))）下面增加一行 if num_boxes == 0: return None, None, None 即可。 希望可以帮到后续的同学
