itom ito::PythonEngine exception

[Johann Krauter]

itom crashed with the exception:

Itom-Application caught an unknown exception from: (ito::PythonEngine) from event type 43 (MetaCall)

when the new dataObjectDetailsDialog is opened for the variable x or y of this code snippets.

import numpy as np

image = np.random.rand(512, 640).astype("float64")
width, height = image.shape
x, y = np.ogrid[:width, :height]
x = dataObject(x)

‌

[Johann Krauter]

x and y seems to be correpted.

When it is converted to a dataobject x = dataObject(x), the RuntimeError:
RuntimeError: Unknown runtime error when executing python command (maybe stack overflow?)

is thrown.

[M. Gronle]

fixes issue 176: fixes a bug when creating a dataObject from a numpy.ndarray, whose stride can be 0 in specific cases. Additionally, less deep copies are created in this constructor, compared to the previous version.
