Are you guys looking into this? This bug is preventing me from reproducing your work.

We haven't seen this problem. Are you using the same AllenNLP version as in the requirements?
Also does this happen for a specific data point or it can't process anything?
Can you send us exact commands for reproducing the error?

I followed the instructions on this page https://github.com/allenai/specter I started in the Download section, ran the conda create pip install then setup.py install. This all worked but when I went to the bottom part where you say to run embed.py, that part fails. I then debugged what embed was calling and that pointed me to this error.

Note I am using anaconda with WSL2.

Hi guys, i am facing the same problem by following the instructions provided including the setups and requirements. i am trying to train using the original train.pkl and val.pkl using the following commands:

./scripts/run-exp-simple.sh -c experiment_configs/simple.jsonnet
-s model-output/ --num-epochs 2 --batch-size 4
--train-path data/preprocessed/train.pkl --dev-path data/preprocessed/val.pkl
--num-train-instances 55 --cuda-device 0

and receive:

TypeError: ArrayField.empty_field: return type None is not a <class 'allennlp.data.fields.field.Field'>.

Would highly appreciate any thoughts on this issue. Cheers

It turns out that there is something wrong with the allennlp installation itself, when i run allennlp on the command line the error shows up. I tried reinstalling the current allennlp version using pip install allennlp but then it shows no module allennlp.run. So i uninstalled allennlp and try reinstalling the requirement with pip and suddenly it works. I dont know how exactly i can replicate the solution but it may give hints to people who are experiencing the same problem.
