stage_map.end() Cannot find Stage for operator placeholder #320

Open hecmay opened 3 years ago

hecmay commented 3 years ago

This is the error mentioned by Mira. The error actually comes from the old TVM part, and it complains that the placeholder op is not found in the stage_map...

This is likely to be caused by the dangling input placeholder not used anywhere... I am checking the error now.
