> I usually start import bugs by trying to re-create a simple repro of the issue and then work from there.
I've managed to get as far as this point. I've tried to boild down the problem to a simple test case which I've added to the issue<http://ironpython.codeplex.com/workitem/26426>. What seems to be happening is this: - import sympy is called - sympy import gets to simpify.py, imports decimal (stdlib) which then imports numbers.py (stdlib) - sympy import gets to function.py, which attempts to import Integer from numbers (sympy) - It fails here because it tries to import Integer from numbers.py (stdlib) The test case works in 2.6.2 but fails in 2.7b1 which seems to indicate a regression. I tried importing the sympy library in 2.6.2 but it fails with: ImportError: No module named signal Richard On Sun, Jan 30, 2011 at 9:16 PM, Dino Viehland <di...@microsoft.com> wrote: > There’s probably an Integer.py somewhere in sympy and this is probably an > import bug.
