Hi @gajendrarao1979, thank you for the pull request! Can you please describe the changes you've made and why are they required?

@vcidst
Currently in rasa main.py the configure_logging_and_warnings function which configures the logging from the config file is called at line 103 and after that configure_colored_logging is called at line 116.

The configure_colored_logging function leverages coloredlogs module which discards and reinitializes logging.StreamHandler. Essentially this overwrites any changes coming from logging.yml (if someone is using StreamHandler).

In my PR I have updated the order of the function call to ensure that logging.yml changes are not overwritten. This is already correct in rasa-sdk code.

I hope this provides the explanation.
