Getting error on running create_data.sh on my own dataset

[tahasadr]

Hi, @weiliu89 I want to train ssd on my own dataset with 3 classes. I edited labelmap_voc.prototxt to support my classes. I also change num_classes to 4 (3 classes + background) in ssd_pascal.py. I can run create_list and generate 3 filses: test.txt, test_name_size.txt and trainval.txt. but when i run create_data.sh i get this error:

F0513 15:52:03.805228 22320 io.cpp:325] Check failed: 'anno' Must be non NULL Check failure stack trace: @ 0x7f68e53b9daa (unknown) @ 0x7f68e53b9ce4 (unknown) @ 0x7f68e53b96e6 (unknown) @ 0x7f68e53bc687 (unknown) @ 0x7f68e582e3bd google::CheckNotNull<>() @ 0x7f68e5829041 caffe::ReadXMLToAnnotatedDatum() @ 0x7f68e582ab9e caffe::ReadRichImageToAnnotatedDatum() @ 0x404b7b main @ 0x7f68e43b5f45 (unknown) @ 0x405ea2 (unknown) @ (nil) (unknown)

maybe the path of your annotation folder is wrong . if you put you data under the VOCdevkit folder as the style of VOC0712.（Annotations ImageSets JPGEimages ），note that the names of the three folders cannot be wrong. then ,run the creat_list and the creat_data ,it will be work

Hi @tahasadr , it would help if you put the previous output of the command. I am facing the same problem as you, i want to train ssd on my own dataset, with 3 classes. I get this error:

It is a very small dataset (80 images)

You guys should go to the code itself and debug the problem

Already solved the problem. Turned out some of the XML annotation files were badly created, with mispelled classes names.

Thank you very much

[tahasadr]

The problem solved. My annotation xml files had some problems.
