Error while determining OS type: module 'platform' has no attribute 'dist'

[gaming master blaster]

Dear Team,

Greetings!

I am trying to run traffic in stateful mode but getting error "Error while determining OS type: module 'platform' has no attribute 'dist'" and after that in last line "Failed resolving dest MAC for default gateway:11.11.11.1 on port 0".

I can see that using arp resolving things fine so is there any relation between above 2 errors and how can i solve it.
