Problem description

Hello,
I recently had 3 gensim models (1 fasttext model and 2 word2vec models) saved using Word2Vec.save() and FastText.save() and I was able to load back all 3 models normally. But recently I attempted to upgrade a couple of packages like numpy and now I get the following error when trying to load back the models:

I'm pretty sure that this is a version mismatch problem but I cannot find a way to find out which version I was using when saving those models :(

Reproduce

Reproducing the bug is only possible if you load the models. They reside on the HuggingFace Hub and you can load them using my library:

pip install hezar

from hezar import Embedding

word2vec = Embedding.load("hezarai/word2vec-cbow-fa-wikipedia")

Same issue, were you able to resolve it?

[arxyzan]

@sauravm8 The only solution was to roll back the versions of numpy and gensim to the same versions they were for training. Mine was numpy==1.24 and gensim==4.3.2
