This error is very unintuitive for end-users, arrays formed from SQL query results can frequently end up as object arrays by accident.

In [15]: arr = np.random.randn(100).astype(object)

In [16]: np.log(arr)

AttributeError Traceback (most recent call last)

H:\workspace\Python\src in ()

AttributeError: log

Same AttributeError is raised for other ufuncs
