Can I have the traceback and the code you ran?

Code I ran:

from altair import load_dataset
import sys
import altair
from altair_widgets import interact_with

df = load_dataset('iris')
interact_with(df, ndims=3)

Traceback with altair_widgets.__version__ == 0.1.2

Looks like altair-widgets is at 0.2.0:

altair_widgets/altair_widgets/__init__.py

Line 2 in 301a3f6

__version__ = '0.2.0'

I'll try uploading to PyPI again.

Resolved the immediate issue by uploading to PyPI; the TypeError is resolved. I'm closing this issue.

I've also made sure the example runs for me. Let me know if it fails for you.
