在python中将np.ndarray转换为np.array

Question

I have some data loaded as a np.ndarray and need to convert it to a np.array.

Is there an easy/quick way of doing this without having to re-load the data in a different way?

All the information I can find in tutorials seems to refer to one type of array or the other, but not how to change data from one to the other.

Answer 1

They are the same: numpy.array is a function that constructs an object of type numpy.ndarray .

>>> import numpy
>>> numpy.ndarray
<type 'numpy.ndarray'>
>>> numpy.array
<built-in function array>
>>> numpy.array([])
array([], dtype=float64)
>>> isinstance(numpy.array([]), numpy.ndarray)
True
