To be honest, I don’t understand its popularity.

For example, I was trying to understand a batch normalization function defined as

def batchnorm_forward(x, gamma, beta, eps):

I can’t tell if gamma/beta are scalar or vector?

We have type annotations in python now which can be used to clarify data types in function signatures.

Wouldn't the default assumption be that you can use either a scalar or vector?

You could try np.isscalar() and np.array().ndim in NumPy.
