VIDIOC_REQBUFS: No such device

[dedetuga]

Hi, I'm trying this on my raspberry pi however I'm getting some erros that I solver but this one I cannot see what is the problem.
So, I run this pi@raspberrypi:~/tensorflow1/models/research/object_detection $ python3 Object_detection_picamera.py --usbcam

and after a while I get the camera image, but 10 sec later I got an error: pi@raspberrypi:~/tensorflow1/models/research/object_detection $ python3 Object_detection_picamera.py --usbcam /usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: compiletime version 3.4 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.5 return f(*args, **kwds) /usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: builtins.type size changed, may indicate binary incompatibility.

The error is every time something _REQBUFS, I fond out if I lower the image sizer I can get this working very well but the problem is with an image size 150x150 I can not see nothing and all the fun is lost.

with a size 200x200 or high I got the error No such device
with a size 150x150 or low everything work great.

Why????
Any idea???
Its just me???
Can I solve it???

Thanks
