About HiCPro2FitHiC.py error

[HW-Superior]

I encountered a problem when using fithic(version 2.0.8) HiCPro2FitHiC.py. The following error as Traceback (most recent call last):
File "/home/user/biosoft/fithic/fithic/utils/HiCPro2FitHiC.py", line 111, in < module>
outputfithicform(args.bed, args.matrix, icounts_output, fragmap_output, args.bias, bias_output, args.resolution)
File "/home/user/biosoft/fithic/fithic/utils/HiCPro2FitHiC.py", line 63, in outputfithicform
value = float(lines.rstrip()) #just one entry that can be nan or a float
ValueError: could not convert string to float: '1\t1\t668.194895'
Can you give me some advice on how I should solve this problem? Thanks!
