Did you changed the layer name? If not, you should try.
In train.prototxt, you need to change num_output in bbox_pred layer. num_output = num_classes * 4
Note: You train with 2 categories, so num_classes should be 3.
layer {
name: "bbox_pred"
type: "InnerProduct"
bottom: "fc7"
top: "bbox_pred"
param { lr_mult: 1.0 decay_mult: 1.0 }
param { lr_mult: 2.0 decay_mult: 0 }
inner_product_param {
num_output: 8 # 2 * 4 - it should be 3 * 4
weight_filler { type: "gaussian" std: 0.001 }
bias_filler { type: "constant" value: 0 }
}
}

@sanghoon dear sanghoon,I got a problem in training my own data with your pva-frcnn.When I use example_train_384,my modification: train.prototxt line11 num_classes : 21 to 2 line6511 num_output84 to 8(When I change this,the train.py can't run) .Check failed: bottom[0]->channels() == bottom[1]->channels() (8 vs. 84) just keep the 84,when the iteration goes to 9980,then: File "./tools/train_net.py", line 112, in
max_iters=args.max_iters)
File "/home/amax/JS/20161123/pva-faster-rcnn/tools/../lib/fast_rcnn/train.py", line 160, in train_net
model_paths = sw.train_model(max_iters)
File "/home/amax/JS/20161123/pva-faster-rcnn/tools/../lib/fast_rcnn/train.py", line 111, in train_model
model_paths.append(self.snapshot())
File "/home/amax/JS/20161123/pva-faster-rcnn/tools/../lib/fast_rcnn/train.py", line 73, in snapshot
self.bbox_stds[:, np.newaxis])
ValueError: operands could not be broadcast together with shapes (84,4096) (8,1)
I trained fasterrcnn(vgg,rfcn) before. What should I do?
