# [SSD Description](#contents)
|
||||
|
||||
|
||||
SSD discretizes the output space of bounding boxes into a set of default boxes over different aspect ratios and scales per feature map location. At prediction time, the network generates scores for the presence of each object category in each default box and produces adjustments to the box to better match the object shape.Additionally, the network combines predictions from multiple feature maps with different resolutions to naturally handle objects of various sizes.

|

The SSD approach is based on a feed-forward convolutional network that produces a fixed-size collection of bounding boxes and scores for the presence of object class instances in those boxes, followed by a non-maximum suppression step to produce the final detections. The early network layers are based on a standard architecture used for high quality image classification, which is called the base network. Then add auxiliary structure to the network to produce detections.

## [Training Process](#contents)
|
||||
|
||||
### Training on Ascend
|
||||
|
||||
To train the model, run `train.py`. If the `mindrecord_dir` is empty, it will generate [mindrecord](https://www.mindspore.cn/tutorial/training/zh-CN/master/advanced_use/convert_dataset.html) files by `coco_root`(coco dataset) or `iamge_dir` and `anno_path`(own dataset). **Note if mindrecord_dir isn't empty, it will use mindrecord_dir instead of raw images.**
|
||||
|
||||
|
||||
- Distribute mode
|
||||
|
||||
```
|
||||
```bash
|
||||
sh run_distribute_train_ghostnet.sh [DEVICE_NUM] [EPOCH_SIZE] [LR] [DATASET] [RANK_TABLE_FILE] [PRE_TRAINED](optional) [PRE_TRAINED_EPOCH_SIZE](optional)
|
||||
```
|
||||
|
||||
We need five or seven parameters for this scripts.
|
||||
|
||||
- `DEVICE_NUM`: the device number for distributed train.
|
||||
|
||||
- `EPOCH_NUM`: epoch num for distributed train.
|
||||
|
||||
- `LR`: learning rate init value for distributed train.
|
||||
|
||||
- `DATASET`：the dataset mode for distributed train.
|
||||
|
||||
- `RANK_TABLE_FILE :` the path of [rank_table.json](https://gitee.com/mindspore/mindspore/tree/master/model_zoo/utils/hccl_tools), it is better to use absolute path.
|
||||
|
||||
- `PRE_TRAINED :` the path of pretrained checkpoint file, it is better to use absolute path.
|
||||
|
||||
- `PRE_TRAINED_EPOCH_SIZE :` the epoch num of pretrained.
|
||||
|
||||
Training result will be stored in the current path, whose folder name begins with "LOG". Under this, you can find checkpoint file together with result like the followings in LOG4/log.txt.
