ValueError: GEOSGeom_createLinearRing_r returned a NULL pointer

Hello~
When I was running "Python train.py -- gpu_idx 0-- batch_size 4-- num_workers 8", the speed was particularly slow, and I had to wait for about five minutes before the first epoch appeared. Later, when the first epoch training reached the 16th round, an error message appeared and the operation stopped. The error message is as follows:

I don't know the reason for this, could you please provide suggestions? Thank you!
