Hi. I am following your blog to use OpenMV in ROS. When I try to do the calibration, it shows that:
Traceback (most recent call last):
File "get_cal_images.py", line 22, in
buf = serial_port.read(size)
File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 488, in read
buf = os.read(self.fd, size - len(read))
OverflowError: signed integer is greater than maximum

I am using Python 2.7. Do you know how to solve this problem? Thanks for your guide.
