I haven't reproduced the issue, but perhaps this method would solve it: (writing line by line to stdout rather than using print) import sys Using the signal module allows just that, as stated in akhan's answer signal.signal() takes a signal to handle as the 1st argument and a handler as the 2nd special handler value SIG_DFL represents the system's default behavior: from signal import signal, SIGPIPE, SIG_DFL In many cases this is more disruptive than helpful, so reverting to the default behavior is desirable:

If a Python script does not catch it, Python outputs error message IOError: Broken pipe and terminates the script with exit code 1 - this is the symptom the OP saw.

This is not necessarily an error condition some Unix utilities such as head by design stop reading prematurely from a pipe, once they've received enough data.īy default - i.e., if the writing process does not explicitly trap SIGPIPE - the writing process is simply terminated, and its exit code is set to 141, which is calculated as 128 (to signal termination by signal in general) + 13 ( SIGPIPE's specific signal number).īy design, however, Python itself traps SIGPIPE and translates it into a Python IOError instance with errno value errno.EPIPE, so that a Python script can catch it, if it so chooses - see Alex L.'s answer for how to do that.Standard Unix signal SIGPIPE is sent to a process writing to a pipe when there's no process reading from the pipe (anymore). I am redirecting the output, so if the above script was named 'open.py', then my command to run would be: open. To bring Alex L.'s helpful answer, akhan's helpful answer, and Blckknght's helpful answer together with some additional information: IOError: Errno 32 Broken pipe I saw on the internet all the complicated ways to fix this, but I copied this code directly, so I think that there is something wrong with the code and not Python's SIGPIPE. See here for background on this solution. You can solve this problem using the following code: from signal import signal, SIGPIPE, SIG_DFL PermissionError: Permission denied: '/home/polina/.local/share/jupyter/runtime/nbserver-4168-open.The problem is due to SIGPIPE handling.

It used to work just fine but I might have messed something up with other installations. I'm getting the following message every time I try to start my jupyter notebook.
