[Challenge2022] error probability don't sum to 1

by yawi yoga

Hi, When running the docker it often complains that packet size probabilities don't sum to 1. For example: "ERROR:root:0: Error using traffic matrix file /data/tm/tm_00000_00000.txt at line 22. The sum of probabilities of all packets sizes should be one" In the above example, the line it complains about is the following: 3,3,5610,0,0,760,0.44,1878,0.48,595,0.08,1 After some checks it seems that the error is due to exact comparison of float sum of probabilities to 1, which may be problematic with floats - e.g. 0.44 + 0.48 + 0.08 is 0.99999999999 and so statement "(0.44 + 0.48 + 0.08) == 1" returns False Is there a newer version of the docker with this fixed?
