Hi, - Githubissues

Hi,

when I run ./download_models.sh., I get the following exception:

Building common vocab
Better speed can be achieved with apex installed from https://www.github.com/nvidia/apex.

RuntimeError: $ Torch: invalid memory size -- maybe an overflow? at /pytorch/aten/src/TH/THGeneral.cpp:188

I tried different (newer) versions of torch, but that lead to the exact same dimension error that JXZe reports in Issue #32 :

      RuntimeError: Trying to create tensor with negative dimension -200001: [-200001, 16]

But in #32 there is no recommendation how to fix this dimension error.

All the packages from requirements.txt are installed correctly, but I have overrides==3.1.0 instead of overrides==6.1.0 as the import "from allennlp.modules.elmo import _ElmoBiLm" in elmo_connector.py didn't work, it worked only after changing to 3.1.0. I also tried to skip the building vocab-part and downloaded the provided common_vocab.txts from the README, but the same Torch: invalid memory size -- maybe an overflow?-error occurs when running run_experiments.py .

Does anybody have an idea how to fix this?
