Error in installation

Hi

I was trying to install NGboost over python2.7. I have faced the following issue:

Collecting ngboost
  Using cached ngboost-0.2.2.tar.gz (22 kB)
    ERROR: Command errored out with exit status 1:

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

Can you please help me with it? I have scipy 1.2.3 installed.

Thanks Jagat

@jagatsesh I'm thinking you'll have to use something like python 3.6, we should also have this explicit in the setup.py to check version (which I can do). I'll keep this open incase any of the other guys have a different suggestion. I just checked by building a new environment with 3.6 and didn't have this issue.

Function annotations in 2.7.. https://stackoverflow.com/questions/42060055/how-can-i-use-function-annotation-in-python-2-7

Thank you for your reply.

Yes, I wil upgrade my modules to python 3.6+ very soon. And then let you know.

@jagatsesh thanks for pointing this out, I'll update the setup.py here shortly. It will make that more clear on install. I'm going to keep this issue open until that PR goes through
