Loadvolume .nrrd file failed in mac, what’s wrong?

 >>> masterVolumeNode = slicer.util.loadVolume("/Users/liguimei/Documents/slicerTempt/pedicle-triangle-planner/testa/vertebra2stl/CT-chest.nrrd")


Traceback (most recent call last):

This function should works well. What Slicer version did you use?

Slicer version is 4.13

I could not reproduce this with the latest Slicer Preview Release on mac. Try the very latest version.

If the problem persists then you can try calling the loadNodes method directly as in the code snippet below and adjust the arguments to see which one caused trouble:

loadedNodesCollection = vtk.vtkCollection()
slicer.app.ioManager().loadNodes('VolumeFile',{'fileName': '/Users/liguimei/Documents/slicerTempt/pedicle-triangle-planner/testa/vertebra2stl/CT-chest.nrrd'}, loadedNodesCollection)
