我的Windows框上安装了ipython。我有pip安装了火焰，但导入错误任何想法

----> 1 import blaze as bz

C:\Python34\lib\site-packages\blaze\__init__.py in <module>()
     16
     17 from datashape import dshape, discover
---> 18 from .utils import ignoring
     19 from .expr import (Symbol, TableSymbol, symbol, ndim, shape)
     20 from .expr import (by, count, count_values, distinct, head, join, label, like,

C:\Python34\lib\site-packages\blaze\utils.py in <module>()
     25 from .dispatch import dispatch
     26
---> 27 thread_pool = ThreadPool(psutil.NUM_CPUS)
     28
     29

AttributeError: 'module' object has no attribute 'NUM_CPUS'
