Python : 'Doc2Vec' object has no attribute 'dv'

Question

Thanks for advice, I have edited the question

I meet this: AttributeError: 'Doc2Vec' object has no attribute 'dv'

The error comes from

AttributeError: 'Doc2Vec' object has no attribute 'dv'

the 'D:/pyspace/headline/headline/utils/model3/doc2vec.model' is an model that has ever been trained.

gensim version is 4.1.2

Django version is 4.0.3

I don't know what should I do to solve this problem. Thanks for help

You should edit your question to include the full error message you're seeing, including lines of traceback showing involved files/code/line-numbers, to help answerers see exactly what's triggering the error. Also, you should generally try to use the latest Gesnim version (4.1.2 as of April 2022) unless you're sure you need to use an older one for a specific reason. Where did this `doc2vec.model` file come from? — gojomo, Apr 04 '22 at 03:50
always put full error message (starting at word "Traceback") in question (not in comments) as text (not screenshot, not link to external portal). There are other useful information. — furas, Apr 04 '22 at 03:58
where did you get `doc2vec.model` ? maybe it can't be used with `Doc2Vec` — furas, Apr 04 '22 at 03:59

It may be the problem of your version, or you can try to correct your code "model.doc2vec"

I tried to reduce the version, but the error keeps the same. I use "Doc2Vec.load( )" to load a model, so where should I correct the code? thanks for your help! – foling Apr 12 '22 at 10:47
