Can I load .npy/.npz files from inside a python package?

Question

I am trying to create my own python package where hopefully one day other people will be able to contribute with their own content. For the package to work it must be possible to have small data files that will be installed as part of the package. It turns out, loading data file that are part of a Python module is not easy. I managed to load very basic ASCII files using something like this:

data = pkgutil.get_data(__name__, "data/test.txt")
data=data.decode('utf-8')
rr = re.findall("[-+]?[.]?[\d]+(?:,\d\d\d)*[\.]?\d*(?:[eE][-+]?\d+)?", data)
        
datanp=np.zeros(len(rr))
for k in range(len(rr)):
    datanp[k]=np.float(rr[k])

I found many comments online that say you should not use commands like np.load(path_to_package) because on some systems packages might actually be stored in zip files or something. That is why I am using pkgutil.get_data() , it is apparently the more robust. Here for example they talk in great length about different ways to safely load data, but not so much how you would actually load different data types.

My question: Are there ways to load .npy files from inside a Python package?
