When i use inference , i meet this problem:

File "infer.py", line 25, in <module>
    model.inference(current_epoch, dataset_infer, save_dir=out_dir)
  File "/home/test/sketch2model/models/view_disentangle_model.py", line 572, in inference
    self.forward_inference()

    out = self.netFull(self.data_image, view=self.data_view)

These changes will fix it, apologies for not having an open PR. I assume this change will break the ability to do training though, certainly, parallelism.

祝你有美好的一天

@duzhenjiang113 Sorry for the late reply. It looks like a DataParallel problem. Which version of PyTorch are you using?
