On a clean install of QR 2.5.0, I noticed that the conda environment is inconsistent out of the box. When attempting to install conda-build, conda tries to update/install the following packages to fix the env:
(base) root@b913d23331fa:/codeload# conda install conda-build
Collecting package metadata (current_repodata.json): done
Solving environment: \
The environment is inconsistent, please check the package plan carefully
The following packages are causing the inconsistency:
- https://repo.continuum.io/pkgs/free/linux-64::anaconda==4.4.0=np112py36_0
failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

Proceed ([y]/n)? n
CondaSystemExit: Exiting.
If you proceed with the fix, zipline will fail to start the next time the container is restarted (I think it's some conflict with dask-core). This makes it impossible to manage Python packages using conda. I think previous versions of QR had inconsistent conda environments, but either QR 2.5 has a change that's more sensitive or some downstream dependency is causing a new failure.
