TypeError: param_init_embedding_layer() missing 2 required positional arguments: 'n_words' and 'dims
See original GitHub issueI have been trying to get nematus to work using the wmt16 model, but I think there is something wrong in the code. I tried to fix it but no matter what I (guessed) to change, it keeps crashing in different places. Here’s the root problem:

If you look at layers.py
, line 76, I think it’s true. But where to get n_words
and dims
from?

Oh, excellent observation! Yes, the code is pretty much unmodified, except that I am using it with python 3.5 and had to adapt a few imports and the renamed
iteritems()
. The solution for my problem is this little typo:note the difference of
{
vs(
.embedding
returned a set instead of a tuple, and python 3 sorted the set according to string length, thus it had the wrong order. python 2.7 doesn’t sort strings in sets at all, it seems to me, so you were lucky 😉If you want, I can create a PR with all my python 3 changes.
Great! I still have the tab open as a TODO reminder, but I just won’t have enough time until December. Guess I’ll be able to close those tabs, too, then 😃
