When I test the model on my own dataset,I get this AP=0 and mAP=0, as follows:

How to fix this error? Thanks!

i also met the same issue. Have you fixed it?

[gmayday1997]

Hi, have you found the reason about it?

[Leerw]

Hi!After my training on my own dataset, it said my background AP is 0 and my interest class AP is 0.905, so I wanna know why the background AP is 0 and does it matter?

[Leerw]

Here is the text:

AP for backgroud = 0.0000
AP for myclass = 0.9025 Mean AP = 0.4513

Results:
0.000
0.903
0.451

[Leerw]

Yes, I have. For me, it was just a small mistake with wrong spelling of 'background'.Good luckfrom Lee.rw-------- 原始邮件 --------主题：Re: [rbgirshick/py-faster-rcnn] AP = 0 & mAP = 0 (#610)发件人：DuanKaiwen 收件人：rbgirshick/py-faster-rcnn 抄送："Lee.rw" ,Mention i also met the same issue.

@Leerw Thank you very much!

Isuccessfully trained resnet model once with accurate result. But now ,iam hitting with the error below: Have anyone got the similar runtime warning.Have you fixed it?please help me.

Hi sulth, I met the same warning, for me, It’s because (1). the number of samples for “truck” and ”bus” are too few compared with “car” (2). There are many small objects in “bus” and “truck” (the size of bus and truck are too small). Good luck!

[wubaorong]

@Leerw Do you meet error in bbox_transform.py?

[Leerw]

Can you describe it in detail?from Li Renwu

[wubaorong]

@Leerw when I train the network,after print iteration 0 , it print this error: /home/wu/faster_rcnn/py-faster-rcnn/tools/../lib/fast_rcnn/bbox_transform.py:48: RuntimeWarning: overflow encountered in exp pred_w = np.exp(dw) * widths[:, np.newaxis] /home/wu/faster_rcnn/py-faster-rcnn/tools/../lib/fast_rcnn/bbox_transform.py:48: RuntimeWarning: overflow encountered in multiply pred_w = np.exp(dw) * widths[:, np.newaxis] /home/wu/faster_rcnn/py-faster-rcnn/tools/../lib/fast_rcnn/bbox_transform.py:49: RuntimeWarning: overflow encountered in exp pred_h = np.exp(dh) * heights[:, np.newaxis] /home/wu/faster_rcnn/py-faster-rcnn/tools/../lib/fast_rcnn/bbox_transform.py:49: RuntimeWarning: overflow encountered in multiply pred_h = np.exp(dh) * heights[:, np.newaxis] /home/wu/faster_rcnn/py-faster-rcnn/tools/../lib/rpn/proposal_layer.py:175: RuntimeWarning: invalid value encountered in greater_equal keep = np.where((ws >= min_size) & (hs >= min_size))[0] Floating Point Exception

[Leerw]

@wubaorong I have not met this problem, it seems your dw or dh is overflow, perhaps you can check your image's size, lol, my idea may not work, good luck

[wubaorong]

@Leerw Thank you very much,I will try this method.

[YoungMagic]

@714586886 Have you solve this problem? I'm using resnet-18 in faster rcnn.Training process is normal. But I got 0 ap for every class. I think the problem is my test.prototxt, but i couldn't figure out why.

[wubaorong]

@714586886 Sorry, I haven't made this step yet. Now I'm training the net, but when I use ZF net to train faster rcnn end2end, in log folder without log file, but if I train faster rcnn alt_opt, the log file could autosaved. Do you know the reasons?

[ZhuangNi]

@714586886 @duoyun1314 @gmayday1997 @Duankaiwwen Mean AP = 0.0000 I have met the same problem. Have you fixed it?

[zqdeepbluesky]

@714586886 @Leerw @duoyun1314 @gmayday1997 @Duankaiwwen hi guys,I met the same problem as you did: /home/zq/faster_rcnn/py-faster-rcnn/tools/../lib/rpn/proposal_layer.py:175: RuntimeWarning: invalid value encountered in greater_equal keep = np.where((ws >= min_size) & (hs >= min_size))[0] Floating Point Exception(core dumped)

can you please help me?I feel so helpless. thanks so much!!!

[wzli1214]

I set the iteration max_iters = [50,50,50,50]. I have got the result like this.

AP for license = 0.0000 Mean AP = 0.0000

Results:
0.000
0.000

What's the problem?

I only trained 2 classes (license + background). Are there some errors with my own data set? I imitated the form of PASCAL VOC to create my own data set.

[zllljf]

When I test the model on my own dataset,I get this AP=0 and mAP=0, as follows:

How to fix this error? Thanks!

hello i also met this problem, and i have checked the class is lower-case like "person", Have you fixed it and how can i fix it?

have you solve the probelm?i met the same problem that i used VOC2007 and there is no spelling error about lower-case,but all of the AP is zero.can you help me ?
