[BUG] .pyc files needs to be deleted before running this project.

An issue occurs when you first try to run the CLI through Python2. This results in creation of Python2 *.pyc files on the local machine. After this if the those files are not deleted and on running Flask UI through Python3 (which uses old Python2 *.pyc file), we get the above error.

*.pyc files interfere with normal working of the project.

This issue can be solved by deleting the *.pyc files from the repository folder from the local machine. Refer to this issue thread for details.

Expected behavior - Delete all the *.pyc files automatically before running the project.
