Hi @Lakshyashishir2 Recently download_file command was implemented in evali-cli. You can find the code here - https://github.com/Cloud-CV/evalai-cli/blob/master/evalai/submissions.py#L185

You have to add documentation for the user in the README as well as in the docs describing on how to use this command. Also, there is an open PR with tests for your reference - https://github.com/Cloud-CV/evalai-cli/pull/173

@Lakshyashishir2 for the GCI task, use The sample command is evalai download_file 'https://evalai.cloudcv.org/web/submission-files?bucket=<s3_bucket_name>&key=<file_path_in_bucket>' as the sample download link.
