Calculate the frame per second of GoogleNet classifier

idata · ‎09-14-2017

is there any way to obtain the FPS of image classifiers models in stream_inference.py ?

Thank you

@ibrahimsoliman python example:

from timeit import default_timer as timer time_start = timer() CODE time_end = timer() print('FPS: %.2f fps' % (1000/(time_end-time_start)))

@macsz Thank you so much

Another way to do the same

from timeit import timeit
def runparallel(count=100, num=[]):
    numdevices = num
    if len(num) == 0: numdevices = range(len(devices))

    for i in range(count):
        # *****************************************************************
        # Load the Tensor to each of the devices
        # *****************************************************************
        for devnum in numdevices:
            img = choice(imgarr)
            graphHandle[devnum].LoadTensor(img, 'user object')

        # *****************************************************************
        # Read the result from each of the devices
        # *****************************************************************
        for devnum in numdevices:
            tensor, userobj = graphHandle[devnum].GetResult()

def runthreaded(count=100,num=[]):
    numdevices = num
    if len(num) == 0: numdevices = range(len(devices))
    thread_list = []
    for ii in numdevices:
        thread_list.append(Thread(target=runparallel, args=(count,[ii],)))

    for thread in thread_list:
        thread.start()
    for thread in thread_list:
        thread.join()

if __name__ == '__main__':
    # *****************************************************************
    # Runs and times runthreaded with 'i' sticks, until all sticks 
    # run at once
    # *****************************************************************
    for i in range(1, len(devices)+1):
      num = str(list(range(i))) 
      tot_time = timeit("runthreaded(count=100,num="+num+")", setup="from __main__ import runthreaded", number=1)    
      print("\n\nRunning " + argv[1] +" on "+str(i)+" sticks threaded      : %0.2f FPS\n\n"%(100.0*i/tot_time))

Thanks @ramana.rachakonda it also worked for me ..
