Biopython после установки

Question

Привет всем Я пытаюсь использовать biopython в mac на python2.7. Я думаю, что я успешно установил Biopython, потому что, когда я тестировал его набрав import Bio

не выход, но когда я набрав from Bio.seq import seq

это ошибка.

from Bio.seq import seq 
>>> import Bio 
>>> from Bio.seq import seq 
Traceback (most recent call last): 
File "<stdin>", line 1, in <module> 
ImportError: No module named seq 
>>> 

Я думаю, что мой путь не является неправильным, потому что, когда я ввожу импорт, он работает.

есть ли кто-нибудь, кто знает возможную причину ??

мой путь

gwagjunseong-ui-MacBook-Pro:~ warren$ echo $PATH 
    /usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/ncbi/blast/bin 

и я установил numpy и протестировали его

но делают ошибки

gwagjunseong-ui-MacBook-Pro:~ warren$ python -c 'import numpy ; numpy.test();'

есть кто-нибудь знает причину?

спасибо!

Нет проблем в установке numpy. Язык Python чувствителен к регистру:

from Bio.Seq import Seq 

Seq является Caps.

>>> from Bio.Seq import Seq 
>>> from Bio.Alphabet import generic_dna, generic_protein 
>>> my_seq = Seq("AGTACACTGGT") 
>>> my_seq 
Seq('AGTACACTGGT', Alphabet()) 
>>> my_dna = Seq("AGTACACTGGT", generic_dna) 
>>> my_dna 
Seq('AGTACACTGGT', DNAAlphabet()) 
>>> my_protein = Seq("AGTACACTGGT", generic_protein) 
>>> my_protein 
Seq('AGTACACTGGT', ProteinAlphabet())
