• PSENet is included in MMOCR.
• We have implemented PSENet using Paddle. You can find the pytorch version here.
• You can find code of PAN here.
• Another group did the same job. You can visit it here. You can also have a try online with all the environment ready here.

Install

Install paddle following the official tutorial.

pip install -r requirement.txt
./compile.sh

Training

CUDA_VISIBLE_DEVICES=0,1,2,3 python dist_train.py ${CONFIG_FILE}

For example:

CUDA_VISIBLE_DEVICES=0,1,2,3 python dist_train.py config/psenet/psenet_r50_ic15_736.py

Test

python test.py ${CONFIG_FILE} ${CHECKPOINT_FILE}

For example:

python test.py config/psenet/psenet_r50_ic15_736.py checkpoints/psenet_r50_ic15_736/checkpoint.pdparams
