Baidu flying general BMN timing action positioning framework | data preparation and training guide (Part 2)

3、 ... and 、BMN

The last part talks about dealing with BMN Training data needed , stay PaddleVideo-develop/applications/FootballAction/datasets/EuroCup2016/features Below this file

（1） Training data processing

open PaddleVideo-develop/applications/FootballAction/datasets/script This directory , Execute under this path ：

python get_instance_for_bmn.py

（2） Modify the configuration file

open PaddleVideo-develop/applications/FootballAction/train_proposal/configs/bmn_football_v2.0.yaml

The first 22、26、31 Change the line to the one just generated ：PaddleVideo-develop/applications/FootballAction/datasets/EuroCup2016/input_for_bmn/label.json The absolute path of

The first 38、49、60 The line should be changed to datasets Absolute path ：PaddleVideo-develop/applications/FootballAction/datasets/EuroCup2016/input_for_bmn/feature

The first 84 That's ok PaddleVideo-develop/applications/FootballAction/BMN_INFERENCE_results And then create a new one called BMN_INFERENCE_results Folder

The first 17 That's ok batchsize Change it to 1

（3） Training BMN

stay PaddleVideo Project root execution ：

python -B -m paddle.distributed.launch --gpus="0" --log_dir=./football/logs_bmn main.py  --validate -c applications/FootballAction/train_proposal/configs/bmn_football_v2.0.yaml -o output_dir=./football/bmn
