  ModuleNotFoundError: No module named '_lzma'
  I've tried to test lightwood with [home rentals
   example](https://github.com/mindsdb/lightwood/blob/master/docs/examples/home_rentals.py) but got ModuleNotFoundError: No module named '_lzma'.

  It looks like _lzma is a dependency to pandas, but it should be included with Python 3.x version.
