The warning has been added to indicate that a second @hashme decorator has been activated before using the information generated by the first hashme in a
with Cell() statement. Nazca warns now by raising an Exception. The hashme inspects the function it decorates and uses that to create a hash of call signature to add to the cell. That hash info is used in the first nd.Cell() call.
You probably tried something like this
import nazca as nd @nd.bb_util.hashme() # A def A(): with nd.Cell(): ... @nd.bb_util.hashme() def B(): A() # call A() which has a hashme, which deletes the B hash with nd.Cell(): # B hash lost at this point ....
The above overwrites the B hash due to the A call.
Better is the following:
@nd.bb_util.hashme() def A(): with nd.Cell(): ... @nd.bb_util.hashme() def B(): with nd.Cell(): # use B hash before calling other hashed functions. A() ....
