Thank you for reporting these errors.

The errors you get mean that you will not be able to use ase-gui and you 
will not be able to write png-files.  The png problem has been fixed in 
the development version and we are working on fixing the ase-gui problem.

So, depending on what you need from ASE, you will need to go back to 
Python 2.7 or forward to the latest development version.
