Toolkit Error: Internal Error of a caffe network including concatination with input

Hi,

The following error occurred when I tried to compile my network including a concat layer by mvNCCompile v02.00:

[Error 17] Toolkit Error: Internal Error: Could not build graph. Missing link: data

The compilation succeeded when I removed the concat layer. So I tested the following simple network and the error happened again:

name: "test_concat"
input: "data"
input_shape
{ dim:1 dim:1 dim:64 dim:64 }

layer {
name: "Convolution"
type: "Convolution"
convolution_param {
num_output: 16
kernel_size: 3
dilation: 1
pad: 1
}
bottom: "data"
top: "Convolution"
}

layer {
name: "BatchNormalization"
type: "BatchNorm"
batch_norm_param {
use_global_stats: true
}
param {
lr_mult: 0
}
param {
lr_mult: 0
}
param {
lr_mult: 0
}
bottom: "Convolution"
top: "BatchNormalization"
}

layer {
name: "ReLU"
type: "ReLU"
bottom: "BatchNormalization"
top: "ReLU"
}

layer {
name: "Concatenate"
type: "Concat"
concat_param {
axis: 1
}
bottom: "ReLU"
bottom: "data"
top: "Concatenate"
}

layer {
name: "Convolution2"
type: "Convolution"
convolution_param {
num_output: 1
kernel_size: 3
dilation: 1
pad: 1
}
bottom: "Concatenate"
top: "Convolution2"
}

layer {
name: "Score"
type: "Sigmoid"
bottom: "Convolution2"
top: "Score"
}

It seems the duplication of the input-data may cause the error. I could not find any restriction from documents. Is it a bug of SDK?

I would appreciate any help.
