Out of memory error - how to reduce batch size? #11

Open 9thDimension opened 4 years ago

9thDimension commented 4 years ago

I'm trying to train a small net on my own dataset. AWS P2 machine with ~12GB of GPU memory.

Getting the error below. Do you know what I can do, perhaps reduce batch size or something? How do I do that?

in setup() - setting cfg.SOLVER.IMS_PER_BATCH = 8 made training run

@9thDimension training works fine but when it comes to testing/evaluation it tries to allocate approx 4 GB. How do I reduce batchsize for test?
