CenterNet is a novel practical anchor-free method for object detection, 3D detection, and pose estimation, which detect identifies objects as axis-aligned boxes in an image. The detector uses keypoint estimation to find center points and regresses to all other object properties, such as size, 3D location, orientation, and even pose. In nature, it's a one-stage method to simultaneously predict center location and bboxes with real-time speed and higher accuracy than corresponding bounding box based detectors.
We support training and evaluation on Ascend910.
Paper: Objects as Points. 2019.
Xingyi Zhou(UT Austin) and Dequan Wang(UC Berkeley) and Philipp Krahenbuhl(UT Austin)
The stacked Hourglass Network downsamples the input by 4×,followed by two sequential hourglass modules.Each hourglass module is a symmetric 5-layer down-and up-convolutional network with skip connections .This network is quite large ,but generally yields the best keypoint estimation performance.
Note that you can run the scripts based on the dataset mentioned in original paper or widely used in relevant domain/network architecture. In the following sections, we will introduce how to run the scripts using the related dataset below.
Dataset used: COCO2017
-
Dataset size：26G
- Train：19G，118000 images
- Val：0.8G，5000 images
- Test: 6.3G, 40000 images
- Annotations：808M，instances，captions etc
-
Data format：image and json files
-
Note：Data will be processed in dataset.py
-
The directory structure is as follows, name of directory and file is user defined:

For more information, please check the resources below：
-
Download the dataset COCO2017.
-
We use COCO2017 as training dataset in this example by default, and you can also use your own datasets.
-
If coco dataset is used. Select dataset to coco when run script.
Install Cython and pycocotool, and you can also install mmcv to process data.
pip install Cython
pip install pycocotools
pip install mmcv==0.2.14
And change the COCO_ROOT and other settings you need in config.py. The directory structure is as follows:
.
└─cocodataset
├─annotations
├─instance_train2017.json
└─instance_val2017.json
├─val2017
└─train2017
-
If your own dataset is used. Select dataset to other when run script.
Organize the dataset information the same format as COCO.

Running on Ascend
bash scripts/run_distributed_train_ascend.sh /path/mindrecord_dataset /path/hccl.json /path/load_ckpt(optional)
The command above will run in the background, you can view training logs in LOG*/training_log.txt and LOG*/ms_log/. After training finished, you will get some checkpoint files under the LOG*/ckpt_0 folder by default. The loss value will be displayed as follows:
# grep "epoch" training_log.txt
epoch: 128, current epoch percent: 1.000, step: 157509, outputs are (Tensor(shape=[], dtype=Float32, value= 1.54529), Tensor(shape=[], dtype=Bool, value= False), Tensor(shape=[], dtype=Float32, value= 1024))

Convert
If you want to infer the network on Ascend 310, you should convert the model to MINDIR:
-
Export on local
python export.py --device_id [DEVICE_ID] --export_format MINDIR --export_load_ckpt [CKPT_FILE__PATH] --export_name [EXPORT_FILE_NAME]
-
Export on ModelArts (If you want to run in modelarts, please check the official documentation of modelarts, and you can start as follows)
# (1) Upload the code folder to S3 bucket.
# (2) Click to "create training task" on the website UI interface.
# (3) Set the code directory to "/{path}/centernet_det" on the website UI interface.
# (4) Set the startup file to /{path}/centernet_det/export.py" on the website UI interface.
# (5) Perform a or b.
# a. setting parameters in /{path}/centernet_det/default_config.yaml.
# 1. Set ”enable_modelarts: True“
# 2. Set “export_load_ckpt: ./{path}/*.ckpt”('export_load_ckpt' indicates the path of the weight file to be exported relative to the file `export.py`, and the weight file must be included in the code directory.)
# 3. Set ”export_name: centernet_det“
# 4. Set ”export_format：MINDIR“
# b. adding on the website UI interface.
# 1. Add ”enable_modelarts=True“
# 2. Add “export_load_ckpt=./{path}/*.ckpt”('export_load_ckpt' indicates the path of the weight file to be exported relative to the file `export.py`, and the weight file must be included in the code directory.)
# 3. Add ”export_name=centernet_det“
# 4. Add ”export_format=MINDIR“
# (7) Check the "data storage location" on the website UI interface and set the "Dataset path" path (This step is useless, but necessary.).
# (8) Set the "Output file path" and "Job log path" to your path on the website UI interface.
# (9) Under the item "resource pool selection", select the specification of a single card.
# (10) Create your job.
# You will see centernet.mindir under {Output file path}.
Infer on Ascend310
Before performing inference, the mindir file must be exported by export.py script. We only provide an example of inference using MINDIR model. Current batch_size can only be set to 1.
#Ascend310 inference
bash run_infer_310.sh [MINDIR_PATH] [DATASET_PATH] [PREPROCESS_IMAGES] [DEVICE_ID]
PREPROCESS_IMAGES Weather need preprocess or not, it's value must be in [y, n]
Result
Inference result is saved in current path, you can find result like this in acc.log file.Since the input images are fixed shape on Ascend 310, all accuracy will be lower than that on Ascend 910.
