Hello, I’m running the default implementation fo Microsoft’s DeBERTa with only one GPU and the implementation does not uses nn.DataParallel, this differs from this issue 5
Running command:
.DeBERTa/experiments/glue/sst2_large.sh

RuntimeError: diff_view_meta->output_nr_ == 0 INTERNAL ASSERT FAILED at "/pytorch/torch/csrc/autograd/variable.cpp":363, please report a bug to PyTorch.

Obs: Changing to torch==1.13.0 solves the issue
