No other mcrInstance can be initialized because blessed init failed.

I am trying to install the matlab runtime on an aws ec2 instance and run some matlab code from python. However i get the following error... SystemError: No other mcrInstance can be initialized because blessed init failed.

Below is a piece of the log.
