Hi,

Getting the following error. I am trying with the pubmed data for "train the CNN encoder with Seq2Seq extractor on gpu 0"

Hi,

I also get the following error. I am trying with the CNN data for "train the CNN encoder with Seq2SeqSentenceExtractor without GPU" I used python3.7.4, torch 1.3 and ignite 1.3. And the environment is Ubuntu 16.04
