Made small changes for full functionality

[GTron-1729]

the '-' sign at lines 319 and 329 generates an error "TypeError: The numpy boolean negative, the - operator, is not supported, use the ~ operator or the logical_not function instead" so i replaced it with '~'

Also i have listed different issues that come while running the code, along with their solutions :)
