YOLOv4, YOLOv4-tiny Implemented in Tensorflow 2.0.
Convert YOLO v4, YOLOv3, YOLO tiny .weights to .pb, .tflite and trt format for tensorflow, tensorflow lite, tensorRT.
+
-Download yolov4.weights file: https://drive.google.com/open?id=1cewMfusmPjYWbrnuJRuKhPMwRe_b9PaT
+## Getting Started
+### Conda (Recommended)
+```bash
+# Tensorflow CPU
+conda env create -f conda-cpu.yml
+conda activate yolov4-cpu
+
+# Tensorflow GPU
+conda env create -f conda-gpu.yml
+conda activate yolov4-gpu
+```
-### Prerequisites
-* Tensorflow 2.3.0rc0
+### Pip
+```bash
+# TensorFlow CPU
+pip install -r requirements.txt
+
+# TensorFlow GPU
+pip install -r requirements-gpu.txt
+```
+### Nvidia Driver (For GPU, if you are not using Conda Environment and haven't set up CUDA yet)
+Make sure to use CUDA Toolkit version 10.1 as it is the proper version for the TensorFlow version used in this repository.
+https://developer.nvidia.com/cuda-10.1-download-archive-update2
### Performance
-
+Check out how YOLOv4 compares to other object detection systems.
+
+
+
+## Downloading Official Pre-trained Weights
+YOLOv4 comes pre-trained and able to detect 80 classes. For easy demo purposes we will use the pre-trained weights.
+Download pre-trained yolov4.weights file: https://drive.google.com/open?id=1cewMfusmPjYWbrnuJRuKhPMwRe_b9PaT
+
+Copy and paste yolov4.weights from your downloads folder into the 'data' folder of this repository.
+
+If you want to use yolov4-tiny.weights, a smaller model that is faster at running detections but less accurate, download file here: https://github.com/AlexeyAB/darknet/releases/download/darknet_yolo_v4_pre/yolov4-tiny.weights
+
+## Using Custom Trained YOLOv4 Weights
+Learn How To Train Custom YOLOv4 Weights here: https://www.youtube.com/watch?v=mmj3nxGT2YQ
+
+USE MY LICENSE PLATE TRAINED CUSTOM WEIGHTS: https://drive.google.com/file/d/1EUPtbtdF0bjRtNjGv436vDY28EN5DXDH/view?usp=sharing
+
+Copy and paste your custom .weights file into the 'data' folder and copy and paste your custom .names into the 'data/classes/' folder.
+
+The only change within the code you need to make in order for your custom model to work is on line 14 of 'core/config.py' file.
+Update the code to point at your custom .names file as seen below. (my custom .names file is called custom.names but yours might be named differently)
+
-### Demo
+Note: If you are using the pre-trained yolov4 then make sure that line 14 remains coco.names.
+## YOLOv4 Using Tensorflow (tf, .pb model)
+To implement YOLOv4 using TensorFlow, first we convert the .weights into the corresponding TensorFlow model files and then run the model.
```bash
# Convert darknet weights to tensorflow
## yolov4
python save_model.py --weights ./data/yolov4.weights --output ./checkpoints/yolov4-416 --input_size 416 --model yolov4
-## yolov4-tiny
+# yolov4-tiny
python save_model.py --weights ./data/yolov4-tiny.weights --output ./checkpoints/yolov4-tiny-416 --input_size 416 --model yolov4 --tiny
-# Run demo tensorflow
-python detect.py --weights ./checkpoints/yolov4-416 --size 416 --model yolov4 --image ./data/kite.jpg
+# custom yolov4
+python save_model.py --weights ./data/custom.weights --output ./checkpoints/custom-416 --input_size 416 --model yolov4
-python detect.py --weights ./checkpoints/yolov4-tiny-416 --size 416 --model yolov4 --image ./data/kite.jpg --tiny
+# Run yolov4 tensorflow model
+python detect.py --weights ./checkpoints/yolov4-416 --size 416 --model yolov4 --images ./data/images/kite.jpg
+# Run yolov4-tiny tensorflow model
+python detect.py --weights ./checkpoints/yolov4-tiny-416 --size 416 --model yolov4 --images ./data/images/kite.jpg --tiny
+
+# Run custom yolov4 tensorflow model
+python detect.py --weights ./checkpoints/custom-416 --size 416 --model yolov4 --images ./data/images/car.jpg
+
+# Run yolov4 on video
+python detect_video.py --weights ./checkpoints/yolov4-416 --size 416 --model yolov4 --video ./data/video/video.mp4 --output ./detections/results.avi
+
+# Run custom yolov4 model on video
+python detect_video.py --weights ./checkpoints/custom-416 --size 416 --model yolov4 --video ./data/video/cars.mp4 --output ./detections/results.avi
+
+# Run yolov4 on webcam
+python detect_video.py --weights ./checkpoints/yolov4-416 --size 416 --model yolov4 --video 0 --output ./detections/results.avi
```
-If you want to run yolov3 or yolov3-tiny change ``--model yolov3`` in command
+If you want to run yolov3 or yolov3-tiny change ``--model yolov3`` and .weights file in above commands.
-#### Output
+Note: You can also run the detector on multiple images at once by changing the --images flag like such ``--images "./data/images/kite.jpg, ./data/images/dog.jpg"``
-##### Yolov4 original weight
-
+### Result Image(s) (Regular TensorFlow)
+You can find the outputted image(s) showing the detections saved within the 'detections' folder.
+#### Pre-trained YOLOv4 Model Example
+
-##### Yolov4 tflite int8
-
+#### Custom YOLOv4 Model Example (see video link above to train this model)
+
-### Convert to tflite
+### Result Video
+Video saves wherever you point --output flag to. If you don't set the flag then your video will not be saved with detections on it.
+
+## YOLOv4 Using TensorFlow Lite (.tflite model)
+Can also implement YOLOv4 using TensorFlow Lite. TensorFlow Lite is a much smaller model and perfect for mobile or edge devices (raspberry pi, etc).
```bash
# Save tf model for tflite converting
python save_model.py --weights ./data/yolov4.weights --output ./checkpoints/yolov4-416 --input_size 416 --model yolov4 --framework tflite
+# Save custom yolov4 tf model for tflite converting
+python save_model.py --weights ./data/custom.weights --output ./checkpoints/custom-416 --input_size 416 --model yolov4 --framework tflite

-python detect.py --weights ./checkpoints/yolov4-416.tflite --size 416 --model yolov4 --image ./data/kite.jpg --framework tflite
+# Run tflite model
+python detect.py --weights ./checkpoints/yolov4-416.tflite --size 416 --model yolov4 --images ./data/images/kite.jpg --framework tflite
+
+# Run custom tflite model
+python detect.py --weights ./checkpoints/custom-416.tflite --size 416 --model yolov4 --images ./data/images/car.jpg --framework tflite
```
+### Result Image (TensorFlow Lite)
+You can find the outputted image(s) showing the detections saved within the 'detections' folder.
+#### TensorFlow Lite int8 Example
+
+
Yolov4 and Yolov4-tiny int8 quantization have some issues. I will try to fix that. You can try Yolov3 and Yolov3-tiny int8 quantization
-### Convert to TensorRT
+
+## YOLOv4 Using TensorRT
+Can also implement YOLOv4 using TensorFlow's TensorRT. TensorRT is a high-performance inference optimizer and runtime that can be used to perform inference in lower precision (FP16 and INT8) on GPUs. TensorRT can allow up to 8x higher performance than regular TensorFlow.
