IPython ImportError by not using absolute_import

Please see this SO question: http://stackoverflow.com/questions/16023318/importerror-when-using-spyder-and-ipython-in-a-virtualenv The error is due to the to modules, the one in widgets and the ipython module itself having the same name "IPython". One way to solve it is with
from future import absolute_import
In spyderlib/widgets/IPython.py

We don't have a file called

spyderlib/widgets/IPython.py

it's called

spyderlib/widgets/ipython.py

which shouldn't give any trouble.

So it seems you are having a problem with your installation. I guess if you eliminate "IPython.py" from your virtualenv your problem would disappear.

By the way, I reproduced the steps you mentioned in your SO post and spyder is working fine for me.

The problem seems to be that I am working in some case-insensitive file system so both files are confused by python. It's the same as here: http://stackoverflow.com/questions/6786644/importing-python-modules-on-linux-from-an-ntfs-share

I'm unfamiliar with

from future import absolute_import

Jed or zahariD, do you know if it could have some unpleasant side effect?

All the imports would look the same and nothing would change in that particular file since you (mean to) use absolute imports everywhere. But a combination of NFTS case-insesitivness and python2 silly import rules turn the ipython import into a relative one.

Only change would be that you would have to change the syntax if you wanted to do relative imports in the module.

For example:

from spyderlib.widgets.mixins import XX

Would still work as it is so no change is needed. However if it was

from mixins import XXX

it would have to change to

from .mixins import XXX

Zahari.

I'm going to take a look at this one for our next release.

This issue was updated by revision 7fd24502e597 .

• The problem is our widget module has the same name (insensitive-wise) as the
  real IPython one. That makes Python 2 to think it has to import
  RichIPythonWidget from our module, which is obviously wrong.
• Thanks to zahariDgmailcom for the fix.

Status: Fixed

Sorry for the big delay in fixing this one. It'll be present in 2.3.
