I solved some of my earlier problems with adjusting the path with the sys.path.append, adding directories where packages are located. However, now I keep getting this error below. I've searched for this error but can't find any mention of it. Can anyone help?

ERROR: Bio.Wise

I am new to Biopython and have tried installing Biopython according to instructions. When I run the test after installing I get  many errors, 96 errors (see below some examples) in all out of 154 test runs. Two errors that keep popping up are  not being able to find module Seq and module Alphabet.

ImportError: No module named Seq

ImportError: No module named Alphabet

NameError: name 'Seq' is not defined

NameError: name 'record' is not defined

NameError: name 'protein_rec' is not defined

NameError: name 'protein_rec' is not defined
