Mmdetection: How to know the Batchsize of the model in MMDetection?

[songyuc]

Hi, guys!
I want to know how to get the batch size of the model in MMDetection?
Because I did not see it in a config file.

Any answer would be appreciated!

imgs_per_gpu=2

imgs_per_gpu=2

@ZwwWayne Have you ever done the experiment about batchsize=1, 2 or 4 in object detection task and which is often better? I don't know why batchsize=1 can also get very good results. Thanks a lot.

FYI:
imgs_per_gpu is now deprecated and renamed as samples_per_gpu, written on config files in configs/ _ base _ /datasets/
