I was using the same code on two different machines, one having installed scikit-image 0.14.2 and the other 0.15.
It seams that since version 0.15 scikit-image is able to read .nrrd images, however it does not correctly read the meta information, which leads to wrong image dimensions. On the other machine using scikit-image 0.14.2 the loader faild to load the .nrrd image and the next loader 'SimpleITK' was used, which could correctly load the image.
