From d9a07a7f6ee8c9afe1665c2c32fd9c75673d40b5 Mon Sep 17 00:00:00 2001 From: Matthew Honnibal Date: Sat, 23 Mar 2019 13:46:25 +0100 Subject: [PATCH] =?UTF-8?q?=F0=9F=92=AB=20Fix=20class=20mismap=20on=20pars?= =?UTF-8?q?er=20deserializing=20(closes=20#3433)=20(#3470)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit v2.1 introduced a regression when deserializing the parser after parser.add_label() had been called. The code around the class mapping is pretty confusing currently, as it was written to accommodate backwards model compatibility. It needs to be revised when the models are next retrained.
