what does the training parameter off hoprec

set -x
Threads=32

# download youtube-links dataset
zipfile="youtube-links.txt.gz"
if test -e "$zipfile";
then
    echo 'zip file exists'
else
    wget http://socialnetworks.mpi-sws.mpg.de/data/youtube-links.txt.gz
fi

# generate the network
zcat youtube-links.txt.gz | awk -F '    ' '{print $1" "$2" 1"}' > net.txt

# run the comment
../cli/hoprec -train net.txt -save rep_dw.txt -undirected 1 -dimensions 64 -walk_times 1 -walk_steps 40 -window_size 5 -negative_samples 5 -alpha 0.025 -threads $Threads

I use this script to test the hoprec algorithm, but it raise the error

Did I use the wrong parameter, looking forward to your help?

In current stage, hoprec requires inputing a .txt file specifying the which vertex is user/item like:

userA u
userB u
userC u
itemA i
itemB i
itemC i
itemD i

by -field arg. We realize it's a bit inconvenience, and we'll fix this in later version.

It means that every algorithm is better to take this form of file as the '-field' input?

now only hoprec requires that

Do you solve this question?And How to input a .txt?
Thanks for you consideration.

Have you solved this question?Could you tell me how to input a .txt?
Thank you.

I found I missed explaining this in -help. I had updated its usage example. please try "-field xxx.txt"
