[IPython-dev] Notebooks enforce specific kernel

[Steve Holden]

Since this may be a configuration issue I thought I'd ask on the list before filing an issue.

I created a Python2 virtual environment and installed IPython[notebook] using pip, plus scipy and some other stuff. I then opened an existing notebook, only to find on executing it that it claims scipy isn't installed.

I noticed that the notebook had automatically opened with a Python 3 kernel, which I found very odd. sys.prefix tells me that it's running Python 3 from a completely unconnected virtual environment.

Now I did, once upon a time, attempt to install a Python2 kernel, but my configuration control isn't good enough to remind me what I did. I can't trace any reference to the "unconnected virtual environment" anywhere in my ~/.ipython directory. This raises two questions:

1: Can anyone tell me where I may have installed this rogue kernel; and

2: It seems notebooks contain a kernel specification of sorts. Does this mean I can't write a notebook that will run in both Python 2 and Python 3?

regards
 Steve
