Hi everybody!

I have a hugh problem and I need to came out with the solution as soon as I can. I want to uso Biopython to download PDB files and this error appears:

Traceback (most recent call last):
  File "C:\Python27\TAREA 3 FINAL.PY", line 33, in <module>
    from Bio.PDB import *
  File "C:\Python27\lib\site-packages\Bio\PDB\__init__.py", line 15, in <module>
    from PDBParser import PDBParser
  File "C:\Python27\lib\site-packages\Bio\PDB\PDBParser.py", line 13, in <module>
    import numpy
ImportError: No module named numpy

I'm not an expert so I'll really hope you can help me.
