Cannot import Paraview 5.8.0 release candidate in python

I cannot import Paraview in Python, both on 5.8.0-rc1 and 5.8.0-rc2, in a Windows distribution.
When trying to import paraview package:

>>> import paraview
Traceback (most recent call last):
  File "C:\Program Files (x86)\ParaView-5.8.0-RC2-MPI-Windows-Python3.7-msvc2015-64bit\bin\Lib\site-packages\paraview\__init__.py", line 175, in <module>
    from .modules import vtkRemotingCore
ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files (x86)\ParaView-5.8.0-RC2-MPI-Windows-Python3.7-msvc2015-64bit\bin\Lib\site-packages\paraview\__init__.py", line 177, in <module>
    import _paraview_modules_static
ModuleNotFoundError: No module named '_paraview_modules_static'

My PYTHONPATH environment variable does contain paths down to site-packages, site-packages\paraview and site-packages\vtkmodules. But it seems like lines 174 to 177 dedicated to static builds make the whole import fail since the exception triggers another bug.

N.B.: I cannot even import vtk:

>>> import vtk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files (x86)\ParaView-5.8.0-RC2-MPI-Windows-Python3.7-msvc2015-64bit\bin\Lib\site-packages\vtk.py", line 30, in <module>
    all_m = importlib.import_module('vtkmodules.all')
  File "C:\Python37\Lib\importlib\__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "C:\Program Files (x86)\ParaView-5.8.0-RC2-MPI-Windows-Python3.7-msvc2015-64bit\bin\Lib\site-packages\vtkmodules\all.py", line 8, in <module>
    from .vtkWebCore import *
ImportError: DLL load failed: The specified module could not be found.
