## Dependencies.
To run the application, you have to:
- The Tencent ncnn framework installed. [Install ncnn](https://qengineering.eu/install-ncnn-on-jetson-nano.html)
- Code::Blocks installed. (```$ sudo apt-get install codeblocks```)
------------
## Installing the app.
To extract and run the network in Code::Blocks
$ mkdir *MyDir*
$ cd *MyDir*
$ wget https://github.com/Qengineering/YoloV7-ncnn-Jetson-Nano/archive/refs/heads/main.zip
$ unzip -j master.zip
Remove master.zip, LICENSE and README.md as they are no longer needed.
$ rm master.zip
$ rm LICENSE
$ rm README.md
Your *MyDir* folder must now look like this:
parking.jpg
busstop.jpg
YoloV7.cpb
yolo.cpp
yolo.h
yoloV7main.cpp
yolov7-tiny.bin
yolov7-tiny.param
------------
## Running the app.
To run the application load the project file YoloV7.cbp in Code::Blocks. More info or
if you want to connect a camera to the app, follow the instructions at [Hands-On](https://qengineering.eu/deep-learning-examples-on-raspberry-32-64-os.html#HandsOn).
------------
### Dynamic sizes.
YoloV7 can handle different input resolutions without changing the deep learning model.
On line 28 of `yolov7main.cpp` you can change the `target_size` (default 640).
Decreasing the size to say 412 will speed up the inference time. On the other hand, the resizing makes the image less detailed; the model will no longer detect all objects.
