| | | ## How to train (Pascal VOC Data): |
|---|
| | | |
|---|
| | | 1. Download pre-trained weights for the convolutional layers (76 MB): http://pjreddie.com/media/files/darknet53.conv.74 and put to the directory `build\darknet\x64` |

| | | 1. Download pre-trained weights for the convolutional layers (154 MB): http://pjreddie.com/media/files/darknet53.conv.74 and put to the directory `build\darknet\x64` |

| | | |

| | | 2. Download The Pascal VOC Data and unpack it to directory `build\darknet\x64\data\voc` will be created dir `build\darknet\x64\data\voc\VOCdevkit\`: |

| | | So if `classes=1` then should be `filters=18`. If `classes=2` then write `filters=31`. |
|---|
| | | |
|---|
| | | **(Do not write in the cfg-file: filters=(classes + 5)x3)** |
|---|
| | | |
|---|
| | | (Generally `filters` depends on the `classes`, `coords` and number of `mask`s, i.e. filters=`(classes + coords + 1)*<number of mask>`, where `mask` is indices of anchors. If `mask` is absence, then filters=`(classes + coords + 1)*num`) |

| | | |
|---|
| | | So for example, for 2 objects, your file `yolo-obj.cfg` should differ from `yolov3.cfg` in such lines in each of **3** [yolo]-layers: |
