i running code in jupyter notebook (here code reference):
import root root f = root.tfile("160721_0828.root") event in f.tree.events: print (1)
it should simple code, looping through file. when run it, kernel crushes , have restart everything. in terminal many errors of kind:
2016-08-08 18:25:20.439 atos[99872:272f] metadata.framework [error]: couldn't client port 0x0000000100000cc4 in start (in python) + 52
before program crushes. using mac, version 10.9.5. cause?
perhaps spotlight indexing disabled , necessary metadata inaccessible.
try turn spotlight indexing on , error message:
"metadata.framework [error]: couldn't client port"
disappears , kernel stable.
