Since I see a "penelope3.py" file, I guess you are using an old version.
Please update to the latest one.

Once you have updated Penelope, you need to create a en_my.zip ZIP file, containing the .dict.dz, .idx, .ifo and .syn files, and then run:
Code:
python -m penelope -i en_my -j stardict -f en -t my -p kobo -o dicthtml-en-my.zip
from the directory containing the en_my.zip file.
