poly in wrong direction?

[iPrayerr]

hey, i've tried to train your model with RCTW dataset.
It works.
However:

Epoch 1 / 30000
126
poly in wrong direction
poly in wrong direction
poly in wrong direction
poly in wrong direction
poly in wrong direction

Then I had to stop.

The label looks as:

390,902,1856,902,1856,1225,390,1225,0,"金氏眼镜"
1875,1170,2149,1170,2149,1245,1875,1245,0,"创于1989"
2054,1277,2190,1277,2190,1323,2054,1323,0,"城建店"
...

Seems that it works in other models' training like ctpr.
Is there anything wrong? I'm really confused.
