Information

Model I am using (Bert, XLNet …): bert-base-uncased

The problem arises when using:

[ X] the official example scripts: (give details below)
my own modified scripts: (give details below)

The tasks I am working on is:

[ X] an official GLUE/SQUaD task: (give the name)
my own task or dataset: (give details below) SQUAD 1.0

To reproduce

Steps to reproduce the behavior:

Install clean transformers environment
run the run_qa.py script with instructions as specified
crash If you go ahead and create a new environment and install the most recent version of the transformer and try to run the run_qa.py script(SQUAD) it crashes because of a parser issue.
