Chalice deploy extremely slow: Overwhelming amount fo 'b "ZipFile" output

[jdc891010]

The chalice deploy is extremely slow, as in, it will take say 10-20 minutes to deploy, and each time I try, it shows an immense amount of code in the terminal, see below:

DEBUG:botocore.endpoint:Making request for OperationModel(name=UpdateFunctionCode) with params: {'url_path': '/2015-03-31/functions/fitness-session-dev/code', 'query_string': {}, 'method': 'PUT', 'headers':

This continue for a few minutes, and happens everytime I try to deploy, even if a zip file is present in the deployments dir.

I have tried to run it with and without "pandas" and "numpy" in the requirements.txt, still the same situation.
