Code Sample, a copy-pastable example if possible
# Not working in full pandas
pd.DataFrame(np.full((5,5), True)) & np.full((1,5), False)
#ValueError: Unable to coerce to DataFrame, shape must be (5, 5): given (1, 5)
# After extracting the numpy array it works as expected:
pd.DataFrame(np.full((5,5), True)).values & np.full((1,5), False)
Problem description
I have a dataframe with shape (m,n), each column filled with bools.
Now I have a numpy (column) vector of length n filled with bools and I would like to apply the logical AND (&) such that the operation is broadcast from the vector onto each column.
This works only when using df.values, not when applying & on the dataframe.
The same holds for other operations such as *, /
I am not sure whether this is intended behaviour - I could not find the matching documentation.
