hi~ Mr.xiong, i have a problem about test with multi gpus,
first i use my own caffe version, when i test the ucf101, i try change tools/eval_net.py code , like this:
i print the my_id(my_id = multiprocessing.current_process()._identity[0]), it is 0,1,2.....200+...,
but i only have 8 gpus,
i see the issue 198 and 160, but still have no idea, could you tell me ? Thanks very much.
hi~ Mr.xiong, i have a problem about test with multi gpus, first i use my own caffe version, when i test the ucf101, i try change tools/eval_net.py code , like this:
caffe.init_gpu_scope([device_id]) caffe.set_device(device_id) caffe.set_mode_gpu()
and then i test on one gpu it has no error, but when i test with multi gpus, i got these errors,
