BUG: Fix ndarray + DataFrame ops by jbrockmendel · Pull Request #23114 · pandas-dev/pandas (original) (raw)

I'm not familiar with exactly how pandas implements binary ops, but this doesn't look like the right place to fix this.

The problem is likely in the DataFrame.__radd__ or DataFrame.__array_ufunc__ method (which NumPy calls instead of __radd__ if defined, see here for details and recommendations)
