# tkDNN
|
|
tkDNN is a Deep Neural Network library built with cuDNN primitives specifically thought to work on NVIDIA TK1(and all successive) board.<br>
|
|
The main scope is to do high performance inference on already trained models.
|
|
|
|
this branch actually work on every NVIDIA GPU that support the dependencies:
|
|
* CUDA 10.0
|
|
* CUDNN 7.603
|
|
* TENSORRT 6.01
|
|
* OPENCV 4.1
|
|
|
|
## Workflow
|
|
The recommended workflow follow these step:
|
|
* Build and train a model in Keras (on any PC)
|
|
* Export weights and bias
|
|
* Define the model on tkDNN
|
|
* Do inference (on TK1)
|
|
|
|
## Compile the library
|
|
Build with cmake
|
|
```
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
# use -DTEST_DATA=False to skip dataset download
|
|
make
|
|
```
|
|
during the cmake configuration it will be dowloaded the weights needed for running
|
|
the tests
|
|
|
|
## Test
|
|
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)
|
|
* test_yolo3_berkeley: our yolo3 version trained with BDD100K dateset
|
|
|
|
## yolo3 berkeley demo detection
|
|
For the live detection you need to precompile the tensorRT file by luncing the desidered network test, this is the recommended process:
|
|
```
|
|
export TKDNN_MODE=FP16 # set the half floating point optimization
|
|
rm yolo3_berkeley.rt # be sure to delete(or move) old tensorRT files
|
|
./test_yolo3_berkeley # run the yolo test (is slow)
|
|
# with f16 inference the result will be a bit incorrect
|
|
```
|
|
this will genereate a yolo3_berkeley.rt file that can be used for live detection:
|
|
```
|
|
./yolo3_demo # launch detection on a demo video
|
|
./yolo3_demo yolo3_berkeley.rt /dev/video0 # launch detection on device 0
|
|
```
