Relay doesn’t support a dictionary, so we cannot convert this op. If you are using huggingface, there is return_dict option that you can use, see Issue: Converting model from pytorch to relay model - #5 by popojames
Otherwise, if the dictionary is the output of your model, you can manually turn it into a tuple, like this: https://github.com/masahi/torchscript-to-tvm/blob/master/transformers/bert_clean.py#L25-L32
