about the wider face data

[Usernamezhx]

hi
I follow your guide to start this project. I download the data WIDER face.but when i run the command:"No dataset given" , i find that the faster_rcnn_end2end.sh scripts only support only voc and coco data. and then i try to convert the wider face data to the voc style . but i meet a new question:assert (boxes[:, 2] >= boxes[:, 0]).all() .i try all i can do ,but it does not work.

The faster_rcnn_end2end.sh script does support the wider dataset. You might need to exactly follow the instructions in the readme file.

hi playerkk
I am a fresh bird,you said the faster_rcnn_end2end.sh script does support the wider dataset,but i open the faster_rcnn_end2end.sh. it said that :
case $DATASET in
pascal_voc)
TRAIN_IMDB="voc_2007_trainval"
TEST_IMDB="voc_2007_test"
PT_DIR="pascal_voc"
ITERS=70000
;;
coco)
# This is a very long and slow training schedule
# You can probably use fewer iterations and reduce the
# time to the LR drop (set in the solver to 350,000 iterations).
TRAIN_IMDB="coco_2014_train"
TEST_IMDB="coco_2014_minival"
PT_DIR="coco"
ITERS=490000
;;
*)
echo "No dataset given"
exit
;;
esac
i have no idea .i need your help,thank you

Are you talking about this file? https://github.com/playerkk/face-py-faster-rcnn/blob/master/experiments/scripts/faster_rcnn_end2end.sh

oh my god ......i use the rbgirshick faster rcnn faster_rcnn_end2end.sh......many many many thanks.......

[Usernamezhx]

i clone your project . thank you very much........ : )

hi playerkk
I am sorry to bother you .I think i should run it first and then to analysis it.
AssertionError: Path does not exist: data/WIDER/train_face_train_annot.txt .
i think it has some problem with the file name .

image_set_file = self._name + 'face' + self._image_set + '_annot.txt'
I think it should not produce the name :train_face_train_annot.txt

I input the command:　**voole@zhx:~/face-py-faster-rcnn$ ./experiments/scripts/faster_rcnn_end2end.sh 0 ZF wider **

thanks for your help

i really really really really really need your help, if you dont have time ,i will be waiting for you.

[playerkk]

I would strongly recommend you to read the instructions carefully before running the cod. https://github.com/playerkk/face-py-faster-rcnn/blob/master/README.md

[Usernamezhx]

I am sorry to bother you again ,I have read the README for several times , http://blog.csdn.net/zhanghongxing007/article/details/56479206
I write down the details, I hope you can read for several minutes, thanks for your help.

[playerkk]

You didn't do the step 4 of the section "prepare the training data".

[Usernamezhx]

first of all . thank you very much. that i use the folder WIDER/WIDER_train/ to Create symlinks. after that , it said that need:
AssertionError: Selective search data not found at: /home/voole/face-py-faster-rcnn/data/WIDER/train.mat
so i down the wider_face_split.zip from the WIDER FACE NET. and then i change the name wider_face_train.mat to train.mat
after that i meet a new problem:
NotImplementedError: Please use HDF reader for matlab v7.3 files
so i have to change the scipy io to fit the v7.3 but................i cant find the loadmat function............

[playerkk]

I tested the repository on another machine. I also had some errors of loading the WIDER dataset. But they are different from yours. I've updated the source files. Please update the repository by doing "git pull origin master" and re-run the program as "./experiments/scripts/faster_rcnn_end2end.sh 0 VGG16 wider"

Sorry for the inconvenience. Let me know if it works.

hi playerkk
First of all ,thanks for your reply. I am sorry to bother you again again again....but i have be here for one day.

wider.mat? it means the wider_face_train.mat?
Look forward to your reply

[playerkk]

It's weird. Since we are using RPN to generate proposals, there is no need to call the _load_selective_search_roidb function. Can you post your command to run the code?

hi playerkk
thanks for your reply. i write down the detail at the : http://blog.csdn.net/zhanghongxing007/article/details/56479206
many thanks.

[playerkk]

Sorry, I should have mentioned only VGG16 is currently supported.

[Usernamezhx]

Hi playerkk
yeah,i use the command:./experiments/scripts/faster_rcnn_end2end.sh 0 VGG16 wider. i use the VGG16 net.

[Usernamezhx]

i have the same quetion .the faster rcnn use the RPN net instead of the selective_search. I called some old script for fast-rcnn ?

[playerkk]

You are training a faster r-cnn. Do you have errors right now?

[Usernamezhx]

when i input the conmmand: './experiments/scripts/faster_rcnn_end2end.sh 0 VGG16 wider'
it still point that : ' Selective search data not found at: /home/voole/face-py-faster-rcnn/data/WIDER/wider.mat'
i am sorry to bother you.

[playerkk]

It seems case sensitive. Try vgg16 instead of VGG16. Also do "git pull origin master" to update the source files.

[playerkk]

You might also need to delete *.pkl files in the cache folder.

hi man
i have solved this question~~~,because of the easydict, my version is 1.4 .even i config the yml. but easydict did not pass the parameter to the train_net.py. so ...... the solution is to update your easydict. thank you very much very much very much .now it works!
