Hi, First of all, thanks for creating EIN. It's brilliant and completely changed the way I work.
I've been using EIN for about 5 months now, using Windows 8.1/WinPython + MSYS + emacs 24.3.1. I run everything locally on a desktop.
Over the past months, I have started getting messages like this when I commands in the notebook from within EIN (I can interact with the same notebook on the same kernel from a browser without any problem at all).
--- Message copied from within emacs EIN buffer --- ERROR:IPKernelApp:Invalid Message Traceback (most recent call last): File "d:\WinPython-64bit-2.7.5.3\python-2.7.5.amd64\lib\site-packages\IPython\zmq\ipkernel.py", line 201, in dispatch_shell msg = self.session.unserialize(msg, content=True, copy=False) File "d:\WinPython-64bit-2.7.5.3\python-2.7.5.amd64\lib\site-packages\IPython\zmq\session.py", line 721, in unserialize raise ValueError("Duplicate Signature: %r"%signature) ValueError: Duplicate Signature: 'e5e94f0e7c96d35179384594a2f012f2' --- EIN message end ---
I run ipython from an msys bash shell, like this (I have included a couple of "duplicate signature" error messages in case it's useful) : ---- bash output begin --- $ ipython notebook --pylab inline fire.ipynb [NotebookApp] Using existing profile dir: u'd:\matthai.ipython\profile_default' [NotebookApp] Serving notebooks from d:\matthai\projects\cmi\fire\src\python\fire [NotebookApp] The IPython Notebook is running at: http://127.0.0.1:8888/ [NotebookApp] Use Control-C to stop this server and shut down all kernels.

Any idea what the problem may be? Thanks!
