Data type added as string when creating variable …array([0., 0., 0., …, 0., 0., 0.], dtype=float32)
When I change my array data type, using .astype() or by adding to np.array(list,dtype=), I get an array which has a string attached. Why is this happening? (example below)
In [1]: A=[1,2,3]
In [2]: A=np.array(A,np.float32)
In [3]: A.dtype
Out[3]: dtype('float32')
In [4]: A
Out[4]: array([1., 2., 3.], dtype=float32)
In [5]: AA=[3,4,5]
In [6]: AA=np.array(AA)
In [7]: AA
Out[7]: array([3, 4, 5])
In [8]: AA.dtype
Out[8]: dtype('int32')
In [9]: AA.astype(np.float32())
Out[9]: array([3., 4., 5.], dtype=float32)

This is not a string: dtype('float32'). It's just one way of representing the dtype for a 32bits float.
If you had strings in your array, you would see:
dtype('S1')
or:
dtype('object')

You're converting your types correctly and the , dtype=float32 attached to your array is not an attached string but just the data type that's displayed in the representation of a Numpy array.
If you do
print(AA)
you will only see your array without any strings following.
