Severity: normal

Hi,

Using %pylab in jupyter qtconsole does not allow to display matplotlib graphics.
Launching the qtconsole from command line exhibits this problem:

ERROR:tornado.application:Exception in callback functools.partial(<function 
wrap.<locals>.null_wrapper at 0x7fedb27dc9d8>)
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/tornado/ioloop.py", line 600, in 
_run_callback
    ret = callback()
  File "/usr/lib/python3/dist-packages/tornado/stack_context.py", line 275, in 
null_wrapper
    return fn(*args, **kwargs)
  File "/usr/lib/python3/dist-packages/ipykernel/kernelbase.py", line 258, in 
enter_eventloop
    self.eventloop(self)
  File "/usr/lib/python3/dist-packages/ipykernel/eventloops.py", line 73, in 
loop_qt4
    _notify_stream_qt(kernel, s)
  File "/usr/lib/python3/dist-packages/ipykernel/eventloops.py", line 23, in 
_notify_stream_qt
    from IPython.core.interactiveshell import NoOpContext as context
ImportError: cannot import name 'NoOpContext'

This problem was identified upstream and corrected in this commit:

https://github.com/ipython/ipython/commit/7cda39691852c19d516f30c4e59e161be05a7b33

Cheers,

Hi,

indeed the problem was fixed upstream some time ago : no need to let
that report linger any longer.

Thanks,

Snark on #debian-python
