Deployment package size limit exceeded while deploying Chalice Application

I am using Chalice as backend for my application but due to n number of dependency to install the package that Chalice is building while deploying .zip file is crossing 50 MB which exceeds the allowed limit of lambda function. I tried to implement the same with setting "automatic_layer": true in config file or enabling layer also that was not working. As i am relaying on Chalice to build and deploy my application I am not able to find a way out to deploy the application using Chalice. What should I do?
