从numpy数组中提取数组

Question

I have data in the following format:

>>> print u.ravel()
[ array([[ -1.29376767e-01],
   [ -1.29525183e-01],
   [ -1.30267263e-01],
   [ -1.31603006e-01]])]

which is an array within a numpy array. I have tried u[:] but I cannot seem to call individual elements from the object.

Could anyone tell me how to extract data from object 'u'?

Thank you in advance.

Answer 1

from the looks of it, it apears u.ravel() returns an array with a numpy array in it. So maybe try

u.ravel()[0][:,:]

[:,:] because it is a two dimensional array
