Syntax error in parallel.py when importing peartree #117

Closed doman84 closed 5 years ago

doman84 commented 5 years ago

Hi,

I have this kind of error after using import peartree as pt

  File "C:\anaconda2\lib\site-packages\peartree\parallel.py", line 18
    target_time_start: int,
                     ^
SyntaxError: invalid syntax

Looks like some very basic problem, but I'm not very well in python :)

Thanks @doman84 for your question. Please also include your version of Python. peartree uses type annotations, and this not supported in earlier versions of Python 3, as well as Py2.

You can see release notes re: type annotations, here: https://docs.python.org/3/whatsnew/3.6.html
