[Pytom-mail] pytom.basic.transformations.project numpy error

[Dustin M. <dus...@gm...>]

Hi all,

When I try to project a subvolume I get the following error:

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)

    611     npprojection = ndarray([v.sizeX(), v.sizeY(), 1], dtype=float32, buffer=None, offset=0, strides=npvol.strides,
    612                            order='F')
--> 613     proj(npvol, axis=2, dtype=float32, out=npprojection)
    614     projection = npy2vol(npprojection,3)
    615     return projection

   1713         return _methods._sum(a, axis=axis, dtype=dtype,

     24     return um.add.reduce(a, axis=axis, dtype=dtype,

     26 
     27 def _prod(a, axis=None, dtype=None, out=None, keepdims=False):

ValueError: output parameter for reduction operation add has too many dimensions

If I add ‘keepdims=True’ to the sum call I get a projection, but is this OK to do?
