行为是否一致。
**A：** 这是由于预测时标签的设置，目标标签是基于原本的标签进行改变，比如原本图片是男生，预测代码对标签进行转变的时候会自动变成相对立的标签，即女性，所以得到的结果是女生。如果想要原本是男生，转变之后还是男生，可以参考模型库中预测代码的StarGAN的标签设置。

# PaddlePaddle Object Detection
This object detection framework is based on PaddlePaddle. We want to provide classically and state of the art detection algorithms in generic object detection and specific target detection for users. And we aimed to make this framework easy to extend, train, and deploy. We aimed to make it easy to use in research and products.
The goal of PaddleDetection is to provide easy access to a wide range of object
detection models in both industry and research settings. we design
PaddleDetection to be not only performant, production-ready but also highly
flexible, catering to research needs.

## Introduction
Major features:
Design Principles:
- Easy to Deploy:
All the operations related to inference are implemented by C++ and CUDA, it makes the detection model easy to deploy in products on the server without Python based on the high efficient inference engine of PaddlePaddle.
We release detection models based on ResNet-D backbone, for example, the accuracy of Faster-RCNN model with FPN based on ResNet50 VD is close to model based on ResNet 101. But the former is smaller and faster.
- Production Ready:
Key operations are implemented in C++ and CUDA, together with PaddlePaddle's
highly efficient inference engine, enables easy deployment in server environments.
- Easy to Customize:
All components are modular encapsulated, including the data transforms. It's easy to plug in and pull out any module. For example, users can switch backbone easily or add mixup data augmentation for models.
- Highly Flexible:
Components are designed to be modular. Model architectures, as well as data
preprocess pipelines, can be easily customized with simple configuration
changes.
- High Efficiency:
Based on the high efficient PaddlePaddle framework, less memory is required. For example, the batch size of Mask-RCNN based on ResNet50 can be 5 per Tesla V100 (16G) when multi-GPU training. The training speed of Yolo v3 is faster than other frameworks.
- Performance Optimized:
With the help of the underlying PaddlePaddle framework, faster training and
reduced GPU memory footprint is achieved. Notably, Yolo V3 training is
much faster compared to other frameworks. Another example is Mask-RCNN
(ResNet50), we managed to fit up to 5 images per GPU (V100 16GB) during
training.
The supported architectures are as follows:

# Introduction
PaddleDetection takes a rather principled approach to configuration management. We aim to automate the configuration workflow and to reduce configuration errors.
# Rationale
Presently, configuration in mainstream frameworks are usually dictionary based: the global config is simply a giant, loosely defined Python dictionary.
This approach is error prone, e.g., misspelled or displaced keys may lead to serious errors in training process, causing time loss and wasted resources.
To avoid the common pitfalls, with automation and static analysis in mind, we propose a configuration design that is user friendly, easy to maintain and extensible.
# Design
The design utilizes some of Python's reflection mechanism to extract configuration schematics from python class definitions.
To be specific, it extracts information from class constructor arguments, including names, docstrings, default values, data types (if type hints are available).
This approach advocates modular and testable design, leading to a unified and extensible code base.
## API
Most of the functionality is exposed in `ppdet.core.workspace` module.
- `register`: This decorator register a class as configurable module; it understands several special annotations in the class definition.
- `__category__`: For better organization, modules are classified into categories.
- `__inject__`: A list of constructor arguments, which are intended to take module instances as input, module instances will be created at runtime an injected. The corresponding configuration value can be a class name string, a serialized object, a config key pointing to a serialized object, or a dict (in which case the constructor needs to handle it, see example below).
- `__op__`: Shortcut for wrapping PaddlePaddle operators into a callable objects, together with `__append_doc__` (extracting docstring from target PaddlePaddle operator automatically), this can be a real time saver.
- `serializable`: This decorator make a class directly serializable in yaml config file, by taking advantage of [pyyaml](https://pyyaml.org/wiki/PyYAMLDocumentation)'s serialization mechanism.
- `create`: Constructs a module instance according to global configuration.
- `load_config` and `merge_config`: Loading yaml file and merge config settings from command line.
## Example
Take the `RPNHead` module for example, it is composed of several PaddlePaddle operators. We first wrap those operators into classes, then pass in instances of these classes when instantiating the `RPNHead` module.
```python
# excerpt from `ppdet/modeling/ops.py`
from ppdet.core.workspace import register, serializable
# ... more operators
@register
@serializable
class GenerateProposals(object):
# NOTE this class simply wraps a PaddlePaddle operator
__op__ = fluid.layers.generate_proposals
# NOTE docstring for args are extracted from PaddlePaddle OP
__append_doc__ = True
def __init__(self,
pre_nms_top_n=6000,
post_nms_top_n=1000,
nms_thresh=.5,
min_size=.1,
eta=1.):
super(GenerateProposals, self).__init__()
self.pre_nms_top_n = pre_nms_top_n
self.post_nms_top_n = post_nms_top_n
self.nms_thresh = nms_thresh
self.min_size = min_size
self.eta = eta
# ... more operators
# excerpt from `ppdet/modeling/anchor_heads/rpn_head.py`
from ppdet.core.workspace import register
from ppdet.modeling.ops import AnchorGenerator, RPNTargetAssign, GenerateProposals
@register
class RPNHead(object):
"""
RPN Head
Args:
anchor_generator (object): `AnchorGenerator` instance
rpn_target_assign (object): `RPNTargetAssign` instance
train_proposal (object): `GenerateProposals` instance for training
test_proposal (object): `GenerateProposals` instance for testing
"""
__inject__ = [
'anchor_generator', 'rpn_target_assign', 'train_proposal',
'test_proposal'
]
def __init__(self,
anchor_generator=AnchorGenerator().__dict__,
rpn_target_assign=RPNTargetAssign().__dict__,
train_proposal=GenerateProposals(12000, 2000).__dict__,
test_proposal=GenerateProposals().__dict__):
super(RPNHead, self).__init__()
self.anchor_generator = anchor_generator
self.rpn_target_assign = rpn_target_assign
self.train_proposal = train_proposal
self.test_proposal = test_proposal
if isinstance(anchor_generator, dict):
self.anchor_generator = AnchorGenerator(**anchor_generator)
if isinstance(rpn_target_assign, dict):
self.rpn_target_assign = RPNTargetAssign(**rpn_target_assign)
if isinstance(train_proposal, dict):
self.train_proposal = GenerateProposals(**train_proposal)
if isinstance(test_proposal, dict):
self.test_proposal = GenerateProposals(**test_proposal)
```
The corresponding(generated) YAML snippet is as follows, note this is the configuration in **FULL**, all the default values can be omitted. In case of the above example, all arguments have default value, meaning nothing is required in the config file.
```yaml
RPNHead:
test_prop:
eta: 1.0
min_size: 0.1
nms_thresh: 0.5
post_nms_top_n: 1000
pre_nms_top_n: 6000
train_prop:
eta: 1.0
min_size: 0.1
nms_thresh: 0.5
post_nms_top_n: 2000
pre_nms_top_n: 12000
anchor_generator:
# ...
rpn_target_assign:
# ...
```
Example snippet that make use of the `RPNHead` module.
```python
from ppdet.core.worskspace import load_config, merge_config, create
load_config('some_config_file.yml')
merge_config(more_config_options_from_command_line)
rpn_head = create('RPNHead')
# ... code that use the created module!
```
Configuration file can also have serialized objects in it, denoted with `!`, for example
```yaml
LearningRate:
base_lr: 0.01
schedulers:
- !PiecewiseDecay
gamma: 0.1
milestones: [60000, 80000]
- !LinearWarmup
start_factor: 0.3333333333333333
steps: 500
```
# Requirements
Two python packages are used, both are optional.
- [typeguard](https://github.com/agronholm/typeguard) is used for type checking in Python 3.
- [docstring\_parser](https://github.com/rr-/docstring_parser) is needed for docstring parsing.
To install them, simply run:
```shell
pip install typeguard http://github.com/willthefrog/docstring_parser/tarball/master
```
# Tooling
A small utility (`tools/configure.py`) is included to simplify the configuration process, it provides 4 commands to walk users through the configuration process:
1. `list`: List currently registered modules by category, one can also specify which category to list with the `--category` flag.
2. `help`: Get help information for a module, including description, options, configuration template and example command line flags.
3. `analyze`: Check configuration file for missing/extraneous options, options with mismatch type (if type hint is given) and missing dependencies, it also highlights user provided values (overridden default values).
4. `generate`: Generate a configuration template for a given list of modules. By default it generates a complete configuration file, which can be quite verbose; if a `--minimal` flag is given, it generates a template that only contain non optional settings. For example, to generate a configuration for Faster R-CNN architecture with `ResNet` backbone and `FPN`, run:
```shell
python tools/configure.py generate FasterRCNN ResNet RPNHead RoIAlign BBoxAssigner BBoxHead FasterRCNNTrainFeed FasterRCNNTestFeed LearningRate OptimizerBuilder
```
For a minimal version, run:
```shell
python tools/configure.py --minimal generate FasterRCNN BBoxHead
```

## Introduction
This is a Python module used to load and convert data into formats for detection model training, evaluation and inference. The converted sample schema is a tuple of np.ndarrays. For example, the schema of Faster R-CNN training data is: `[(im, im_info, im_id, gt_bbox, gt_class, is_crowd), (...)]`.
The data pipeline is responsible for loading and converting data. Each
resulting data sample is a tuple of np.ndarrays.
For example, Faster R-CNN training uses samples of this format: `[(im,
im_info, im_id, gt_bbox, gt_class, is_crowd), (...)]`.
### Implementation
This module is consists of four sub-systems: data parsing, image pre-processing, data conversion and data feeding apis.
We use `dataset.Dataset` to abstract a set of data samples. For example, `COCO` data contains 3 sets of data for training, validation, and testing respectively. Original data stored in files could be loaded into memory using `dataset.source`; Then make use of `dataset.transform` to process the data; Finally, the batch data could be fetched by the api of `dataset.Reader`.
The data pipeline consists of four sub-systems: data parsing, image
pre-processing, data conversion and data feeding APIs.
Data samples are collected to form `dataset.Dataset`s, usually 3 sets are
needed for training, validation, and testing respectively.
Sub-systems introduction:
1. Data prasing
By data parsing, we can get a `dataset.Dataset` instance, whose implementation is located in `dataset.source`. This sub-system is used to parse different data formats, which is easy to add new data format supports. Currently, only following data sources are included:
First, `dataset.source` loads the data files into memory, then
`dataset.transform` processes them, and lastly, the batched samples
are fetched by `dataset.Reader`.
Sub-systems details:
1. Data parsing
Parses various data sources and creates `dataset.Dataset` instances. Currently,
following data sources are supported:
- COCO data source
This kind of source is used to load `COCO` data directly, eg: `COCO2017`. It's composed of json files for labeling info and image files. And it's directory structure is as follows:

- Roidb data source
This kind of source is a normalized data format which only contains a pickle file. The pickle file only has a dictionary which only has a list named 'records' (maybe there is a mapping file for label name to label id named 'canme2id'). You can convert `COCO` or `VOC` data into this format. The pickle file's content is as follows:

A generalized data source serialized as pickle files, which have the following
structure:
```python

2. Image preprocessing
Image preprocessing subsystem includes operations such as image decoding, expanding, cropping, etc. We use `dataset.transform.operator` to unify the implementation, which is convenient for extension. In addition, multiple operators can be combined to form a complex processing pipeline, and used by data transformers in `dataset.transformer`, such as multi-threading to acclerate a complex image data processing.
3. Data transformer
The function of the data transformer is used to convert a `dataset.Dataset` to a new `dataset.Dataset`, for example: convert a jpeg image dataset into a decoded and resized dataset. We use the decorator pattern to implement different transformers which are all subclass of `dataset.Dataset`. For example, the `dataset.transform.paralle_map` transformer is for multi-process preprocessing, more transformers can be found in `dataset.transform.transformer`.
4. Data feeding apis
To facilitate data pipeline building and data feeding for training, we combine multiple `dataset.Dataset` to form a `dataset.Reader` which can provide data for training, validation and testing respectively. The user only needs to call `Reader.[train|eval|infer]` to get the corresponding data stream. `Reader` supports yaml file to configure data address, preprocessing oprators, acceleration mode, and so on.
2. Image preprocessing
the `dataset.transform.operator` module provides operations such as image
decoding, expanding, cropping, etc. Multiple operators are combined to form
larger processing pipelines.
3. Data transformer
Transform a `dataset.Dataset` to achieve various desired effects, Notably: the
`dataset.transform.paralle_map` transformer accelerates image processing with
multi-threads or multi-processes. More transformers can be found in
`dataset.transform.transformer`.
4. Data feeding apis
To facilitate data pipeline building, we combine multiple `dataset.Dataset` to
form a `dataset.Reader` which can provide data for training, validation and
testing respectively. Users can simply call `Reader.[train|eval|infer]` to get
the corresponding data stream. Many aspect of the `Reader`, such as storage
location, preprocessing pipeline, acceleration mode can be configured with yaml
files.
The main APIs are as follows:
1. Data parsing
- `source/coco_loader.py`: Use to parse the COCO dataset. [detail code](https://github.com/PaddlePaddle/models/blob/develop/PaddleCV/object_detection/ppdet/data/source/coco_loader.py)
- `source/voc_loader.py`: Use to parse the Pascal VOC dataset. [detail code](https://github.com/PaddlePaddle/models/blob/develop/PaddleCV/object_detection/ppdet/data/source/voc_loader.py)
[Note] When using VOC datasets, if you do not use the default label list, you need to generate `label_list.txt` using `tools/generate_data_for_training.py` (the usage method is same as generating the roidb data source) or provide `label_list.txt` in `data/pascalvoc/ImageSets/Main` firstly. Also set the parameter `use_default_label` to `false` in the configuration file.
- `source/loader.py`: Use to parse the Roidb dataset. [detail code](https://github.com/PaddlePaddle/models/blob/develop/PaddleCV/object_detection/ppdet/data/source/loader.py)
- `source/coco_loader.py`: COCO dataset parser. [source](https://github.com/PaddlePaddle/models/blob/develop/PaddleCV/object_detection/ppdet/data/source/coco_loader.py)
- `source/voc_loader.py`: Pascal VOC dataset parser. [source](https://github.com/PaddlePaddle/models/blob/develop/PaddleCV/object_detection/ppdet/data/source/voc_loader.py)
[Note] To use a non-default label list for VOC datasets, a `label_list.txt`
file is needed, one can use the provided label list
(`data/pascalvoc/ImageSets/Main/label_list.txt`) or generate a custom one (with `tools/generate_data_for_training.py`). Also, `use_default_label` option should
be set to `false` in the configuration file
- `source/loader.py`: Roidb dataset parser. [source](https://github.com/PaddlePaddle/models/blob/develop/PaddleCV/object_detection/ppdet/data/source/loader.py)

<a name="mix">[1]</a> Please refer to [this paper](https://arxiv.org/pdf/1710.09412.pdf)。
`transform/arrange_sample.py`: Assemble the data samples needed by different models.
3. Transformer
`transform/post_map.py`: A pre-processing operation for completing batch data, which mainly includes:
``` python
Randomly adjust the image size of the batch data
Multi-scale adjustment of image size
Padding operation
```
`transform/transformer.py`: Used to filter useless data and return batch data.
`transform/parallel_map.py`: Used to achieve acceleration.
`transform/post_map.py`: Transformations that operates on whole batches, mainly for:
- Padding whole batch to given stride values
- Resize images to Multi-scales
- Randomly adjust the image size of the batch data

`reader.py`: Combine source and transforms, return batch data according to `max_iter`.
`data_feed.py`: Configure default parameters for `reader.py`.
### Usage
#### Ordinary usage
The function of this module is completed by combining the configuration information in the yaml file. The use of yaml files can be found in the configuration file section.
#### Canned Datasets
- Read data for training
Preset for common datasets, e.g., `MS-COCO` and `Pascal Voc` are included. In
most cases, user can simply use these canned dataset as is. Moreover, the
whole data pipeline is fully customizable through the yaml configuration files.
``` python
ccfg = load_cfg('./config.yml')
coco = Reader(ccfg.DATA, ccfg.TRANSFORM, maxiter=-1)
```
#### How to use customized dataset?
- Option 1: Convert the dataset to the VOC format or COCO format.
```python
# In ./tools/, the code named labelme2coco.py is provided to convert
# the dataset which is annotatedby Labelme to a COCO dataset.
#### Custom Datasets
- Option 1: Convert the dataset to COCO or VOC format.
```sh
# a small utility (`tools/labelme2coco.py`) is provided to convert
# Labelme-annotated dataset to COCO format.
python ./tools/labelme2coco.py --json_input_dir ./labelme_annos/
--image_input_dir ./labelme_imgs/

```
- Option 2:
1. Following the `./source/coco_loader.py` and `./source/voc_loader.py`, add `./source/XX_loader.py` and implement the `load` function.
2. Add the entry for `./source/XX_loader.py` in the `load` function of `./source/loader.py`.

#### How to add data pre-processing？
- If you want to add the enhanced preprocessing of a single image, you can refer to the code of each class in `transform/operators.py`, and create a new class to implement new data enhancement. Also add the name of this preprocessing to the configuration file.
- If you want to add image preprocessing for a single batch, you can refer to the code for each function in `build_post_map` of `transform/post_map.py`, and create a new internal function to implement new batch data preprocessing. Also add the name of this preprocessing to the configuration file.
- To add pre-processing operation for a single image, refer to the classes in
`transform/operators.py`, and implement the desired transformation with a new
class.
- To add pre-processing for a batch, one needs to modify the `build_post_map`
function in `transform/post_map.py`.

# Getting Started
Please refer [installation instructions](INSTALL.md) to install PaddlePaddle and prepare dataset at first.
For setting up the test environment, please refer to [installation
instructions](INSTALL.md).
## Train a Model
## Training
#### Single-GPU Training
#### One-Device Training
```bash
export CUDA_VISIBLE_DEVICES=0
# export CPU_NUM=1 # for CPU training
python tools/train.py -c configs/faster_rcnn_r50_1x.yml
```
#### Multi-Device Training
#### Multi-GPU Training
```bash
export CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 # set devices
# export CPU_NUM=8 # for CPU training
export CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7
python tools/train.py -c =configs/faster_rcnn_r50_1x.yml
```
- Default dataset directory is `dataset/coco`, users also can specify it in the configure file.
- Pretrained model will be downloaded automatically and saved at `~/.cache/paddle/weights`.
- Model will be saved at `output/faster_rcnn_r50_1x` by default, users also can specify it in the configure file.
- All hyper parameters can refer input config.
- Change config file for other models.
- For more help, please run `python tools/train.py --help`.
- Datasets is stored in `dataset/coco` by default (configurable).
- Pretrained model is downloaded automatically and cached in `~/.cache/paddle/weights`.
- Model checkpoints is saved in `output` by default (configurable).
- To check out hyper parameters used, please refer to the config file.
Alternating between training epoch and evaluation run is possible, simply pass
in `--eval=True` to do so (tested with `SSD` detector on Pascal-VOC, not
recommended for two stage models or training sessions on COCO dataset)
For `SSD` on Pascal-VOC dataset, set `--eval=True` to do evaluation during training.
For other models based on COCO dataset, the evaluating during training is not fully verified, better to do evaluation after training.
## Evaluate with Pretrained models.
## Evaluation
```bash
export CUDA_VISIBLE_DEVICES=0
# export CPU_NUM=1 # for CPU training
# or run on CPU with:
# export CPU_NUM=1
python tools/eval.py -c configs/faster_rcnn_r50_1x.yml
```
- The default model directory is `output/faster_rcnn_r50_1x`, you also can specify it.
- For R-CNN and SSD models, do not support evaluating by multi-device now, we will enhanced it in next version.
- For more help, please run `python tools/eval.py --help`.
- Checkpoint is loaded from `output` by default (configurable)
- Multi-GPU evaluation for R-CNN and SSD models is not supported at the
moment, but it is a planned feature
## Inference
## Inference with Pretrained Models
- Infer one image:
- Run inference on a single image:
```bash
export CUDA_VISIBLE_DEVICES=0
python tools/infer.py -c configs/faster_rcnn_r50_1x.yml --infer_img=demo/000000000139.jpg
# or run on CPU with:
# export CPU_NUM=1
python tools/infer.py -c configs/faster_rcnn_r50_1x.yml --infer_img=demo/000000570688.jpg
```
- Infer several images:
- Batch inference:
```bash
export CUDA_VISIBLE_DEVICES=0
# or run on CPU with:
# export CPU_NUM=1
python tools/infer.py -c configs/faster_rcnn_r50_1x.yml --infer_dir=demo
```
The predicted and visualized images are saved in `output` by default, users can change saved directory by specifying `--savefile=`. For more help please run `python tools/infer.py --help`.
The visualization files are saved in `output` by default, to specify a different
path, simply add a `--save_file=` flag.
## FAQ
Q: Why the loss may be NaN when using single GPU to train?
Q: Why do I get `NaN` loss values during single GPU training?
A: The default learning rate is adapt to multi-device training, when use single GPU and small batch size, you need to decrease `base_lr` by corresponding multiples.
A: The default learning rate is tuned to multi-GPU training (8x GPUs), it must
be adapted for single GPU training accordingly (e.g., divide by 8).

# Task Description
Given a dialogue goal g and a set of topic-related background knowledge M = f<sub>1</sub> ,f<sub>2</sub> ,..., f<sub>n</sub> , the system is expected to output an utterance "u<sub>t</sub>" for the current conversation H = u<sub>1</sub>, u<sub>2</sub>, ..., u<sub>t-1</sub>, which keeps the conversation coherent and informative under the guidance of the given goal. During the dialogue, the system is required to proactively lead the conversation from one topic to another. The dialog goal g is given like this: "Start->Topic_A->TOPIC_B", which means the machine should lead the conversation from any start state to topic A and then to topic B. The given background knowledge includes knowledge related to topic A and topic B, and the relations between these two topics.<br>
