when I try to load a caffe model with OpenCV 3.4.3, I get the error
what(): OpenCV(3.4.3) /home/schneider/libs/opencv-3.4.3/modules/dnn/src/dnn.cpp:412: error: (-2:Unspecified error) Can't create layer "DummyData1" of type "DummyData" in function 'getLayerInstance'*
The layer in the prototxt file looks like this:
layer {
name: "DummyData1"
type: "DummyData"
top: "DummyData1"
dummy_data_param {
shape {
dim: 1
dim: 32
dim: 125
dim: 100
}
}
}
It appears that the layer is missing in OpenCV. The caffe layer is described here on the Caffe webpage, but I am not sure how to implement this layer in OpenCV. Has it already been implemented somewhere? How can I solve this problem?
if you able to change a .protptxxt the file you can replace these line to the following ones. Try this gys
layer {
type: "Input"
name: "DummyData1"
top: "DummyData1"
input_param {
shape {
dim: 1
dim: 32
dim: 125
dim: 100
}
}
}
or
input: "DummyData1"
input_dim: 1
input_dim: 32
input_dim: 125
input_dim: 100

I am getting into the programming of networks with caffe and since I am used to more comfortable and "lazy" solutions I am a bit overwhelmed by the problems that can occur.
Right now I am getting the error
Check failed: status == CUDNN_STATUS_SUCCESS (3 vs. 0) CUDNN_STATUS_BAD_PARAM
This one is quite well known to be produced by bad cuda or cudnn versions.
So i checked those and they are up to date. (Cuda: 8.0.61 Cudnn: 6.0.21)
Since I will only get this error when I add this ReLU layer I suppose it is caused by me confusing a parameter:
layer{
name: "relu1"
type: "ReLU"
bottom: "pool1"
top: "relu1"
}
And to give you all the information, here is the error message I get:

As you can see the first Convolutional layer will take an input of size (50 227 227 3), wich is a bit problematic, since he thinks that the second dimension contains the channels.
Its only natural that this convolutional layer will simply butcher the dimensions that way and now no further layer after that will get proper input dimensions.
I managed to solve the problem by simply reshaping the input this way:
layer {
name: "reshape"
type: "Reshape"
bottom: "data"
top: "res"
reshape_param {
shape {
dim: 50
dim: 3
dim: 227
dim: 227
}
}
}
the first dimension in this is the batch size, so whoever reads this has to remember to set this dim to 1 in the .prototxt file for the classification phase (since that one won't work with batches)
EDIT: I will mark this as an answer since it covers the basic solution to the problem i had and no other solution is in sight. If anyone wants to shine more light on the matter, please do so.
The reason why it is throwing this error is because you have no more room to "shrink". From your error message: 50 1 224 0 (0)
This indicates the size of the net has a 0 in one dimension.
To fix this error, you can tweak some of the parameters, including (S)tride, (K)ernel size, and (P)adding. To calculate the dimensions of your next layer (W_new), you can use the formula:
W_new = (W_old - K + 2*P)/S + 1
So, if we have an input that is 227x227x3 and our first layer has K = 5, S = 2, P = 1, and numOutputs = N, conv1 then has a dimension that is:
(227-5+2*1)/2 + 1 = 112x112xN.
Note: if you end up with an odd number in the numerator, round up after adding 1.
Edit: The reason why it's showing up with the ReLU layer is likely because the ReLU layer has nothing to pass through, ergo it throws an error.
I use torch-caffe-binding to convert caffe model to torch. And I want to delete the loss layer in the end and add other torch layers, could I just delete the layer in the .prototxt file and "train" the model to get the .caffemodel file and import in torch?
And the model uses the lmdb type data, when I use net:forward(input) to train the model, the model just uses the data defined in the data layer instead of uses the inputdata. So how to train the model that uses the lmdb data?
the caffe model has some custom layer so I can't use the loadcaffe to load the model in torch
You have 3 issues here -
You probably need the loss layer for the training (this is what you
want to minimize). So train with it, and after the training is done
remove it from your prototxt before converting to torch.
In order to use the lmdb rather than using the data layer, connect
your input to the first conv layer (assuming your first non-input
layer is conv, e.g. say you have
layer {
name: "input-data"
type: "DummyData"
top: "data"
top: "im_info"
dummy_data_param {
shape { dim: 1 dim: 3 dim: 224 dim: 224 }
}
}
and also
input: "data"
input_shape: {
dim: 1
dim: 3
dim: 224
dim: 224
}
and then
layer {
name: "conv1"
type: "Convolution"
bottom: "data" --> **here put data instead of input-data**
top: "conv1"
convolution_param {
num_output: 96
kernel_size: 3
pad: 1
stride: 1
}
}
As for the custom layer, you'll have to find an equivalent
implementation in torch or implement it on your own
I have a lasagane code. I want to create the same network using caffe. I could convert the network. But i need help with the hyperparameters in lasagne. The hyperparameters in lasagne look like:
lr = 1e-2
weight_decay = 1e-5
prediction = lasagne.layers.get_output(net['out'])
loss = T.mean(lasagne.objectives.squared_error(prediction, target_var))
weightsl2 = lasagne.regularization.regularize_network_params(net['out'], lasagne.regularization.l2)
loss += weight_decay * weightsl2
How do i perform the L2 regularization part in caffe? Do I have to add any layer for regularization after each convolution/inner-product layer? Relevant parts from my solver.prototxt is as below:
base_lr: 0.01
lr_policy: "fixed"
weight_decay: 0.00001
regularization_type: "L2"
stepsize: 300
gamma: 0.1
max_iter: 2000
momentum: 0.9
also posted in http://datascience.stackexchange.com. Waiting for answers.
It seems like you already got it right.
The weight_decay meta-parameter combined with regularization_type: "L2" in your 'solver.prototxt' tell caffe to use L2 regularization with weight_decay = 1e-5.
One more thing you might want to tweak is how much regularization affect each parameter. You can set this for each parameter blob in the net via
param { decay_mult: 1 }
For example, an "InnerProduct" layer with bias has two parameters:
layer {
type: "InnerProduct"
name: "fc1"
# bottom and top here
inner_product_param {
bias_term: true
# ... other params
}
param { decay_mult: 1 } # for weights use regularization
param { decay_mult: 0 } # do not regularize the bias
}
By default, decay_mult is set to 1, that is, all weights of the net are regularized the same. You can change that to regularize more/less specific parameter blobs.
I know this may be better asked in caffe user group but I cannot access the user group and don't know where to pose the question as I'm not sure whether this needs to be raised as an issue in git. In any case, what I'm doing is this:
I have a set of grayscale images that I want to use to train a CNN using caffe. I'm using a modified version of the provided caffenet model definitions with minor modifications (ie: channel = 1 instead of 3 as I have grayscale images). So far, I used the imagenet provided mean image to train the CNN and it trained and generated results. Now I wanted to compute the image mean of my own train/test dataset and use that as the mean image so I used the file in build/tools/ to do this. It needed the images to be in lmdb so I first converted images to lmdb using convert_imageset and then used compute_mean to compute the mean. I ensured that I use --gray flag when using convert_imageset as my images are grayscale. When I rerun caffe, I get the following error. From what I can understand, it's a channel mismatch but I have no idea how to fix this. Any help on this is very much appreciated.

I have the following in train_val.prototxt

layer {
name: "data"
type: "Input"
top: "data"
input_param { shape: { dim: 10 dim: 3 dim: 227 dim: 227 } }
}
You (or the interface) have failed to adjust the input for gray scale. Gray has only 1 input channel (value); the model expects 3 channels (RGB). That 3 in the layer's top shape should be 1.
Look in your *.prototxt files for something like this near the top (input layer):
shape {
dim: 10
dim: 3
dim: 227
dim: 227
}
These dimensions are batch_size, channels, rows, and columns. Wherever you have something on this order (there should be only one, and only in input files), change the 3 to 1.
I figured out how to do this. In the train_val.prototxt, there's an image_data_param section under data layer. I had to add is_color: false in it and that fixed the issue.
Thanks everyone for comments and replies, appreciate it.
I am trying to implement a pixel-wise binary classification for images using caffe. For each image having dimension 3x256x256, I have a 256x256 label array in which each entry is marked as either 0 or 1. Also, when I read my HDF5 file using the below code,
dirname = "examples/hdf5_classification/data"
f = h5py.File(os.path.join(dirname, 'train.h5'), "r")
ks = f.keys()
data = np.array(f[ks[0]])
label = np.array(f[ks[1]])
print "Data dimension from HDF5", np.shape(data)
print "Label dimension from HDF5", np.shape(label)
I get the data and label dimension as
Data dimension from HDF5 (402, 3, 256, 256)
Label dimension from HDF5 (402, 256, 256)
I am trying to feed this data into the given hdf5 classification network and while training, I have the following output(using the default solver, but in GPU mode).

Basically the error is
softmax_loss_layer.cpp:42] Check failed:
outer_num_ * inner_num_ == bottom[1]->count() (10 vs. 655360)
Number of labels must match number of predictions;
e.g., if softmax axis == 1 and prediction shape is (N, C, H, W),
label count (number of labels) must be N*H*W,
with integer values in {0, 1, ..., C-1}.
I am not able to understand why the number of labels expected is just same as my batch size. How exactly should I tackle this problem ? Is this a problem with my labeling method ?
Your problem is that "SoftmaxWithLoss" layer tries to compare a prediction vector of 2 elements per input image to a label of size 256-by-256 per image.
This makes no sense.
Root cause of the error: I guess what you tired to do is to have a binary classifier applied to each pixel in the image. To that end you defined "fc1" as an "InnerProduct" layer with num_output=2. However, the way caffe sees this is that you have a single binary classifier applied to the entire image. Thus caffe gives you a single binary prediction to the entire image.
How to solve: when working on pixel-wise predictions you no longer need to use "InnerProduct" layers and you have a "fully convolutional net". If you replace "fc1" with a conv layer (for instance a kernel that examine the 5-by-5 environment of each pixel and makes a decision according to this patch):
layer {
name: "bin_class"
type: "Convolution"
bottom: "data"
top: "bin_class"
convolution_param {
num_output: 2 # binary class output
kernel_size: 5 # 5-by-5 patch for prediciton
pad: 2 # make sure spatial output size equals size of label
}
}
Now applying "SoftmaxWithLoss" to bottom: bin_class and bottom: label should work.
