can't find ipython... about pudb

[inducer]

Did you choose IPython in the preferences? (Ctrl-P)

[xuchen]

yep! Also I saw ipython was written in .config/pudb

[inducer]

As in, yep, solved, or, yep, still a problem?

[xuchen]

ooops, yep, still a problem! :-(

[inducer]

Please try if this happens with the version from git.

[xuchen]

yes, it still happens. How does pudb find ipython? if you can provide some steps, I'm willing to help debug.

[inducer]

Check

https://github.com/inducer/pudb/blob/master/pudb/shell.py

for the code that does the interfacing with IPython.

I found out that pudb.shell.HAVE_IPYTHON isn't set to true in the pudb shell. There's sth weird that I can't explain:

I modified shell.py to:

try:
    import IPython
except ImportError:
    HAVE_IPYTHON = False
    print 'have it!'
else:
    HAVE_IPYTHON = True
    print 'dont have it!'

When I first hit !, I got:

have it!
Hit Ctrl-D to return to PuDB.

Then I continued to type:

>>> import pudb.shell as shell
>>> shell.HAVE_IPYTHON
False

note here upon "import pudb.shell as shell" I didn't get either "have it!" or "dont have it!", which means the modified shell.py isn't executed. How come??? I checked my disk and didn't find another version of pudb installed.

If I run the above from a normal python shell, I would have shell.HAVE_IPYTHON == True, only inside a pudb-invoked python shell did I get shell.HAVE_IPYTHON == False

[xuchen]

Ooops, I just found out my print 'have it!'/print 'dont have it!' insertion should've switched their places...

anyways, the issue is that pudb seems not able to import IPython even though I can import it both from a normal python shell and the pudb-invoked python sehll.

OK, I've identified the problem but couldn't explain why. I minimized to:

have a file called t.py containing only 1 line: "import IPython"

If I put this file to the pudb folder and run it, I have:

Traceback (most recent call last): File "t.py", line 1, in import IPython File "/home/xuchen/bin/lib/python2.7/site-packages/pudb-2012.1-py2.7.egg/pudb/IPython.py", line 6, in from IPython.frontend.terminal.interactiveshell import \ ImportError: No module named frontend.terminal.interactiveshell

At this time a file IPython.pyc was generated in the same folder, but no source file IPython.py.

If I put the file t.py into any other folders other than the pudb folder, it runs no problem. Any insight?

[inducer]

I think you have two different versions of IPython installed on your machine. This is not looking like a pudb issue.
