in this line, i got error like this

TypeError: Highway.forward: input must be present

Can anyone help me?

Can produce a similar error, here's the traceback:

FWIW this happens on Google Colab, I haven't tried on local.

@paleboot, I had the same error

[paleboot]

So this is how I managed to get it to work on Colab. Keep in mind that this is just a naive attempt to debug using informations from the traceback that I got. I am by no means experienced in pytorch, so I don't really know any implications that this will cause. YMMV

1. Clone the repo as per usual
2. Open ELMoForManyLangs/elmoformanylangs/modules/highway.py
3. Edit line 47-48:

47     def forward(self, inputs: torch.Tensor) -> torch.Tensor:  # pylint: disable=arguments-differ
48         current_input = inputs

to

47    def forward(self, *input: torch.Tensor) -> None:  # pylint: disable=arguments-differ
48        current_input = input[0]

4. Install via pip: pip install -e ELMoForManyLangs/

[saleems11]

I had changed the python version and suddenly it works.

[paleboot]

I had changed the python version and suddenly it works.

Which version did you change to? Is it 3.5?

[saleems11]

No, I had to change it to 3.7 and downloaded torch 1.8.1+cu11.1 on their website, hope this could help.

Turns out the culprit is simpler than I thought; the addition of signature check in overrides v5.0.0. The fix is simply by adding check_signature=False in line 46 of ELMoForManyLangs/elmoformanylangs/modules/highway.py:

46    @overrides(check_signature=False)

I've opened PR #96 as a permanent fix, hopefully it gets merged.

It seems work as a charm.

Thanks a lot. It works for me.
