Will installation from source in different conda env lead to conflict?
I want to install a nightly-version(v1.2) of pytorch from source in a new conda env, and I got v1.1 outside conda env installed from pip.

Will that lead to conflict?

If you didn't change anything else about your environment, then not. Conda shields its environment from the host environment in the sense that it comes with its own python distribution, libraries etc., hence there should be no conflicts.

Note, however, that conda also comes with pip, so you need to make sure that the pip you used to install v1.1 is indeed your host's pip and not conda's own pip.
