ERROR: testOpExportSlot.TestOpExportSlot.testBasic_Dvid

[jakirkham]

This test is currently failing with an error. It appears internalOutput doesn't have a dtype in meta. Not sure how this could happen. As it is an error in testing DVID, maybe @stuarteberg has some insight. Traceback below.

The error appeared between these two commits in lazyflow ( 85312d8 ) and ( e5b5c36 ). Was using pydvid with commit ( janelia-flyem/pydvid@15ca567 ), which is the current master.

This bug was introduced via c832c82, now fixed via 1826e5d

[jakirkham]

Yep, that appears to fix it.
