rfcn convert_model.py problem

[wuxiaolian]

I can train the rfcn_res50,but when I run the convert_model.py,I got a problem:"Key error,bbox_pred_pre",And there isn't 'bbox_pred_pre' layer in test.protext.

@makefile
Traceback (most recent call last):
File "/data/code/caffe/convert_model.py", line 91, in
(net.params['bbox_pred'][0].data * stds[:, np.newaxis])
KeyError: 'bbox_pred'
I got a problem too，I just comment this line of code.

@moyans There is no need run the convert_model.py since bbox unnormalize is done at test time in the C++ code.

I have trained rfcn model and bbox accuracy got 97%, but when inference got no result, I am not convert model..... with:

BUILD=build/examples/FRCNN/demo_frcnn_api.bin

@jinfagang Try lower the threshold, if there is no object, that may be caused by wrong labels used for training.

@makefile Just simply using VOC, this data is veryfied training with zf-fasterrcnn, it worked. And the network loaded and trained, but inference got no result. Also, when I convert model it says no layer called bbox_pred which this issue got.

So I don't convert directly inference using demo_frcnn_api, it gots no result, not sure what's the problem, the threshold is 0.3 is already low enough.

@jinfagang I had the same problem .Have you solved it?

@SuperPowerLF2 No idea so far.
