Re: [Rdkit-discuss] problems with installation on conda with python 3.5 32-bit

[Michal K. <mic...@gm...>]

Hi Greg,
Thanks for your reply. Actually, >50% of my (prospective) users are stuck
on 32-bit. It would be really nice to have a python3 build (even once a
year) but I understand that the demand is low and waning. I guess the
solution is to use python2.7 for the time being...
Thanks and kind regards,
Michal
