I tried to convert a Torch pretrained model from https://github.com/tyshiwo/FSRNet. However it crashed when I run the scripts. Here is the error info:

Greatly appreciate if you can fix it.

Hi @kingiw I'm trying too to convert the model from https://github.com/tyshiwo/FSRNet but I have the same issue like you. Did you fixed the issue ?
Thanks
