If you think of the norms as a length, you easily see why they can’t be negative. – Vector Norms are 0 if and only if the vector is itself a zero vector. – Norms follow the triangular inequality (The norm of the sum of some vectors is less than or equal to the sum of the norms of these vectors).

Webord defines the vector norm that is computed. The following norms are supported: where inf refers to float (‘inf’), NumPy’s inf object, or any equivalent object. dtype may be used to perform the computation in a more precise dtype. It is semantically equivalent to calling linalg.vector_norm (x.to (dtype)) but it is faster in some cases. See also http://mathonline.wikidot.com/the-norm-of-a-vector how many inches is 5 feet long
