Error when preparedb

[chiquif23]

Hello, how are you?

When I try preparedb: vsflow preparedb -i test.csv -o test.vsdb -s -c -f ecfp -np 12 --boost

it keeps in a bucle with this output:

Gave up normalization after 200 restarts Gave up normalization after 200 restarts Gave up normalization after 200 restarts

Thanks!!!
