一维numpy数组浮动

Question

I want to convert a 1D numpy array to a simple float (no array). How is that done? Here is my current code with the variable 'acc'.

print type(acc)
print acc.shape

>>> <type 'numpy.ndarray'>
>>> (1,)

Answer 1

Can't you just do:

float(acc)

To make it a float? Seems to be working here:

a = np.array([1])
print a.shape
print type(a)
print float(a)

yields

(1,)
<type 'numpy.ndarray'>
1.0
