The environment is inconsistent, please check the package plan carefully

The inconsistencies are caused due to different versions of the packages, and their clashing dependencies.

conda update --all

This command updates all the packages, and then conda solves the inconsistency on its own.

saw this on Google Groups

This message was added in conda 4.6.9, previously there was no indication when conda detected an inconsistent environment unless conda was run in debug mode. It is likely that your environment was inconsistent for some time but the upgrade to conda made it visible. The best option it to run "conda install package_name" for the inconsistent packages to let conda try to restore consistency.

and it really works for me.

Maybe you should try conda install anaconda in your situation.

I had faced the same problem. Simply running

conda install anaconda

solved the problem for me.
