Now that you know a little about me, let me tell you about the issue I am having:

Description of Issue

• I fetch the commit 080874c, and want to check test_algorithm.py should pass nosetests
• two tests failed test_good_kwargs and test_without_kwargs
• failure of the above two all points to this AttributeError: 'zipline.lib._float64window.AdjustedArrayWindow' object has no attribute 'seek'
• since this commit has passed nosetests on travis CI, I'm wondering why it fails on my machine?
• details as follows:

@mickeydonkey you're getting this error because the commit you pulled included changes to Cython files, which need to be recompiled to take effect. The easiest way to do this if you're running from a github checkout is to run:

python setup.py build_ext --inplace

Before I ran pip install -e . , I deleted all .so and .c files and the build subdirectory to make installation clean but it doesn't make any change. Anyway, your magic works for me, thank you! @ssanderson
