Dask + pyinstaller fails

For using dask with PyInstaller you need to add dask.yaml and distributed.yaml to your output executable with add-data flag:

pyinstaller -F --add-data "<python_path>/Lib/site-packages/dask/dask.yaml;./dask" --add-data "<python_path>/Lib/site-packages/distributed/distributed.yaml;./distributed" script.py
