Encounting NotImplementedError when finetuning a Single-Task .pth model

[darkgezi]

i take a pretrained-single-task model for finetuning I just modified the training data part of the model's input.json. The finetune command: dp --pt train input.json -t dpa2.pth --use-pretrain-script.

The error is as follow:

Traceback (most recent call last):

The input.script is here:
input.json

Is this because the pth model is used instead of the pt model?
