the return of "fgim_attack"

[Icyzrw]

Great work!
but there is an issue about "fgim_attack" since it return nothing, but "eval_iters" wants to save the results of it to the file.

Thanks again for your job!

Thank you! "fgim_attack" aims to generate the outputs under a fixed modification weight W, to show that different modification weights W can control the obviousness of the target attribute in the generated sentence (as shown in Section “4.5 Transfer Degree Control”).
