# tkDNN
tkDNN is a Deep Neural Network library built with cuDNN primitives specifically thought to work on NVIDIA TK1 board.<br>
The main scope is to do high performance inference on already trained models.
Currently supports the following layers:
* Dense, fully interconnected
* Activation (RELU, ELU, SIGMOID, TANH)
* Convolutional 2D
* Convolutional 3D
* Max and Average Pooling
* Flatten
* Data preprocessing
this branch is actually work on every NVIDIA GPU that support the dependencies:
* CUDA 8
* CUDNN 6
* TENSORRT 2

cmake ..
make
```
during the cmake configuration it will be dowloaded the weights needed for running
the tests
## Test
There is a ready to use example on *test* directory, to try it you must generate the weights with Keras
```
cd tests
python test_model.py
```
And then execute the inference on build directory
```
cd build
./tkDNNtest
```
this should output the same prediction as Keras.
Assumiung you have correctly builded the library these are the test ready to exec:
* test_simple: a simple convolutional and dense network (CUDNN only)
* test_mnist: the famous mnist netwok (CUDNN and TENSORRT)
* test_mnistRT: the mnist network hardcoded in using tensorRT apis (TENSORRT only)
* test_yolo: YOLO detection network (CUDNN and TENSORRT)
* test_yolo_tiny: smaller version of YOLO (CUDNN and TENSRRT)
## Simple example
Here is a example of the entire workflow on a simple model.
Using the following Keras model save it to a file
```python
model = Sequential()
model.add(Reshape((20, 1), input_shape=(20)))
model.add(Dense(256))
model.compile()
# save model
model.save("path/to/model.h5")
```
After the model is created the weights can be exported for tkDNN inference
```
python weights_exporter model.h5 dense --output=weights/path
```
the exporter take as arguments, in order:
* input model
* layer type ["dense", "conv2d", conv3d"]
* { layer type ["dense", "conv2d", conv3d"] for each layer to export }
* optional argument --output define path where export weights
Then we can create a c++ program to do inference on tk1
```c++
#include<tkdnn.h> //library include
//Network object
tkDNN::Network net;
//input dimension
tkDNN::dataDim_t dim(1, 20, 1, 1, 1);
//Dense layer
tkDNN::Dense d0(&net, dim, 256, "weights/path", "bias/path");
//here load the input data to CUDA
//value_type is an alias of "float"
value_type *data_d = [...]
//do inference
value_type *output_d = d0.infer(dim, data_d);
//dim will be updated with the output dimension
```
The result is finally stored on output_d in device memory.
