Python build crashes when locking to face

[SkyRatInd]

Same issue as previous but different debug, this time I'm not running the exe I built from python

face detection lock = True
Traceback (most recent call last):
  File "get_pulse.py", line 213, in <module>
    App.main_loop()
  File "get_pulse.py", line 181, in main_loop
    self.processor.run(self.selected_cam)
  File "C:\Users\WorldMachine\Downloads\webcam-pulse-detector-no_openmdao\lib\processors_noopenmdao.py", line 207, in run
    idx2 = np.argmax(pruned)
  File "C:\Users\WorldMachine\AppData\Local\Programs\Python\Python37\lib\site-packages\numpy\core\fromnumeric.py", line 1037, in argmax
    return _wrapfunc(a, 'argmax', axis=axis, out=out)
  File "C:\Users\WorldMachine\AppData\Local\Programs\Python\Python37\lib\site-packages\numpy\core\fromnumeric.py", line 51, in _wrapfunc
    return getattr(obj, method)(*args, **kwds)
ValueError: attempt to get argmax of an empty sequence

Is is also affecting the exe versions.

@SkyRatInd @wgaylord @thearn Any solution for this so far? Facing the same problem on Ubuntu 18.04, python 3.6.7.

I have also encountered this error.Hence looked through the code and found that it is because of low fps camera.In code when I remove the lower bound or increase the upper bound then the issue is resolved idx = np.where((freqs > 50) & (freqs < 180)) line number 199 in processors_noopenmdao.py however this effects the output and hence the BPM calculated is very inaccurate .

Most webcams are 23 or so FPS (basically bear min.)

just solved it out.It is basically because of temp file created in temp folder ,Try removing it and it will work .Temp files are the root of the problem.

@RahanSharma, can you tell us what temp file you are talking about?

[SijinJohn]

@RahanSharma , where are the temp files??

How to solve this problem? I have tried 2 cams, 24fps and 60fps, both didn't work......

Same issue here. I'm on Win10, Python v3.7.0 using built in camera.

[MarkusvonStaden]

Temp files seems possible, since it worked the first time, but I cannot find any tempfiles
