interactive.py script hangs for first iteration

[Bibhuti93]

When I am trying to invoke scripts/pipeline/interactive.py using default tokenizer as CoreNLP the program gets stuck as shown in the screenshot below.

Please find below the screenshot of exception when I terminate the program with Ctrl+C

The issue gets resolved when I am terminating the interactive shell using Ctrl+C and again invoking the "process" function. During the second invocation the process works fine as expected.

Could you please help me in identifying the cause for this so that the program can be invoked in the first go ?
