Hi @neelr Thanks for the PR. The build is failing due to two reasons -

1. Flake8 formatting error.
2. Output format doesn't match with the test's output.

@neelr

1. To find out where flake8 problem exists, installing flake8 on your computer and running it on your branch would list all the formatting requirements which are missing. You can install it using python -m pip install flake8 and run on the repo as flake8 ~/dir/evalai-cli.

2. It is related to the pytests which are written to check the output of a CLI command. But while running the task, the output is NULL as reported in the build. (the ' ' symbol).

evalai-cli/evalai/utils/challenges.py:256:23: W504 line break after binary operator
