Ioerror: [errno 5] Input/output Error Odoo
IOError Input/Output Error When Printing up vote 13 down vote favorite 1 I have inherited some code which is periodically (randomly) failing due to an Input/Output error being raised during a call to print. I am trying to determine the cause of the exception being raised (or at least, better understand it) and how to handle it correctly. When executing the following line [errno 5] input/output error django of Python (in a 2.6.6 interpreter, running on CentOS 5.5): print >> sys.stderr, 'Unable to do something: %s' % command The exception is raised (traceback omitted): IOError: [Errno 5] Input/output error For context, this is generally what the larger function is trying to do at the time: from subprocess import Popen, PIPE import sys def run_commands(commands): for command in commands: try: out, err = Popen(command, shell=True, stdout=PIPE, stderr=PIPE).communicate() print >> sys.stdout, out if err: raise Exception('ERROR -- an error occurred when executing this command: %s --- err: %s' % (command, err)) except: print >> sys.stderr, 'Unable to do something: %s' % command run_commands(["ls", "echo foo"]) The >> syntax is not particularly familiar to me, it's not something I use often, and I understand that it is perhaps the least preferred way of writing to stderr. However I don't believe the alternatives would fix the underlying problem. From the documentation I have read, IOError 5 is often misused, and somewhat loosely defined, with different operating systems using it to cover different problems. The best I can see in my case is that the python process is no longer at

I have installed the dependencies: sudo apt-get update sudo apt-get install build-essential python-dev python-smbus python-pip git I have installed the software for the Python MPR121 Library: cd ~ git clone https://github.com/adafruit/Adafruit_Python_MPR121.git and I have installed the library: cd Adafruit_Python_MPR121 sudo python setup.py install But when I try to run: cd examples sudo python simpletest.py I continue to get the error code: IOError: http://raspberrypi.stackexchange.com/questions/51126/ioerror-errno-5-input-output-error [Errno 5] Input/output error I have been reading different questions on here that are similar to my issue, but I have not been able to find an answer that fixes my specific problem.

The error is clear. Presumably you have not connected your device to the I2C bus properly. What steps have you taken to verify the bus is working? –joan Jul 12 at 13:47 :/ "IOError" can seem a bit ambiguous. It would be good if you included a photograph of the sensor connected to the pi -- I know this seems simple, but it is common for people to have problems with this kind of thing because of a simple mistake with the connection, such as a backward ribbon cable (which, beware, can cause permanent physical damage to the pi). –goldilocks♦ Jul 12 at 13:54 @goldilocks Thank you for the advice! Here are 2 pictures of my current setup. –Elyse Zurawski Jul 12 at 14:34 @joan I have updated my post with the steps I have taken so far. If you have any advice on what my next approach should be, that would
