I tried multi classification, but the following error occurs when training. any solution?.

Hi Aditya,

thank you very much for reporting this problem!

Some parts of the examples seem to have not been adapted to recent changes. I fixed this just now and released 1.0.0a6.
If you reinstall now (pip install small-text[pytorch]==1.0.0.a6) this problem should be solved.

In case you are using a newer pytorch version, also have a look at issue #2 (and downgrade pytorch if necessary).
