hm, I can't imagine why that wouldn't work, then.

What do you get for:

get_ipython().extension_manager.ipython_extension_dir

And what IPython version?

from ipython_extensions.

In [77]:

get_ipython().extension_manager.ipython_extension_dir

Out[77]:

u'/Users/Stian/.ipython/extensions'

Version 0.13.1, using EPD (but have upgraded iPython using enpkg).

One more thing - what are the contents of that autosave.py in your
extensions folder?

Okay, then everything seems to be working perfectly. What if you define your own extension, just put an empty foo.py in your extension folder, and try %load_ext foo. If that doesn't work, something is wrong with your IPython installation, and you should bring that up as an IPython issue.

from ipython_extensions.

That went fine.

%load_ext foo

Well, now that doesn't make even the slightest bit of sense. %load_ext autosave doesn't work, even after %load_ext foo does?

from ipython_extensions.

Of course, now it works perfectly. Apart from playing with different
notebooks, I am quite sure I have not touched the IPython setup. I'm sorry
if I have wasted your time, but glad that it works.

from ipython_extensions.

okay - I wonder why it didn't work. Might be something funky if you run %install_ext and %load_ext in the same session.
