thanks,one of the output is:
[12/17 03:23:47] d2.evaluation.evaluator INFO: Inference done 4946/5000. Dataloading: 0.0012 s/iter. Inference: 0.0556 s/iter. Eval: 0.0167 s/iter. Total: 0.0735 s/iter. ETA=0:00:03
how to compute FPS

[zhanghang1989]

The inference time is 0.0556 s/iter

You can calculate fps = batch_size / 0.0556

[kirkzZ]

I set --num-gpus 4 SOLVER.IMS_PER_BATCH 16
and when test:
start inference on 5000 batches,

inference time is0.0556 s/iter,

total inference time is 0:06:07.214419,

the fps=5000/367.2 ?

Where does the 367.2 comes from?
