I think the problem you are experiencing is that the ALPS Conda package is built only with Python 2.7. In Coda you can easily have multiple version of Python installed, then you should be able to use the ALPS package.

Hi, I try to use $conda install -c conda-forge alps to install ALPS using the most updated anaconda package. However, I got the error message suggesting some dependency issue.

UnsatisfiableError: The following specifications were found to be in conflict:

• alps
• navigator-updater

Use "conda info <package>" to see the dependencies for each package.

As I try to use conda info navigator-updater to check what is happening, it somehow suggest navigator-updater 0.1 is build using python 3.6. Is it why I get the dependency issue? If so, can I still using anaconda to install ALPS? or I need to build it from the source files?

Thanks a lot. Yi-Ping
