Segmentation Fault (core dumped) on Azure VM

[AschHarwood]

Steps to reproduce

1. Set up and install pytext and dependencies on Azure VM based on instructions provided on pytext repository
2. Run pytext train < docnn_nst.json

I should also note I got the exact same error using the terminal in a floydhub workspace with a PyTorch 1.5 environment as well as on AWS sagemaker with both the PyTorch and basic data science kernels. It worked just fine locally on my MacBook

Observed Results

(pytext_venv) aschharwood@nstv3:~/test/pytext_test$ pytext train < docnn_nst.json Segmentation fault (core dumped)

Expected Results

I expected it to train a model and print out the various metrics a la the basic example on the pytext docs page.
