Why can't I use scipy.linalg after importing scipy?

If I run the following two lines of code:

import numpy
numpy.linalg

I do not get an error, and I get the output <module 'numpy.linalg' from /Users/...>.

However, if I run the following two lines of code

import scipy
scipy.linalg

I get the error

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-7-7ed633b28ccc> in <module>
      1 import scipy
----> 2 scipy.linalg

AttributeError: module 'scipy' has no attribute 'linalg'

However, the following code seems to work fine:

import scipy.linalg
scipy.linalg

My question is: how come after importing numpy, I can use numpy.linalg, but I can't do the same for scipy?

For context, I am using numpy version 1.19.2, and I am using scipy version 1.4.1.

There is a line in "numpy/__init__.py", which is the module initialization file, that explicitly imports linalg:

from . import linalg

There is no such line in "scipy/__init__.py". That is why you must import scipy.linalg yourself.
