+# [How to Perform YOLO Object Detection using OpenCV and PyTorch in Python](https://www.thepythoncode.com/article/yolo-object-detection-with-opencv-and-pytorch-in-python)
+To run this:
+- `pip3 install -r requirements.txt`
+- Download the model weights and put them in `weights` folder.
+- To generate a object detection image on `images/dog.jpg`:
+    ```
+    python yolo_opencv.py images/dog.jpg
+    ```
+    A new image `dog_yolo3.jpg` will appear which has the bounding boxes of different objects in the image.
+- For live object detection:
+    ```
+    python live_yolo_opencv.py
+    ```
+- If you want to read from a video file and make predictions:
+    ```
+    python read_video.py video.avi
+    ```
+    This will start detecting objects in that video, in the end, it'll save the resulting video to `output.avi`
+- If you wish to use PyTorch for GPU acceleration, please install PyTorch CUDA [here](https://pytorch.org/get-started) and use `yolo.py` file.
+- Feel free to edit the codes for your needs!
