prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  [MAINT] AttributeError: module 'kymatio' has no attribute '__version__'
  This came up in #172
  
  PEP 396 has introduced the convention of exposing the constant `__version__` to the top-level module
  At the moment this is in `kymatio.version.version` (so that `version.py` can be loaded in `setup.py` without importing the whole `kymatio` module)
  https://www.python.org/dev/peps/pep-0396/
  
  Will submit a PR later
