Research direction
Look at the source code of 'ConcatenatedDoc2Vec' in gensim/models/doc2vec.py. The attribute 'corpus count' is missing; it might need to be defined or accessed from the underlying models. Check if the issue is related to the training loop in the user's script. See the comments in the issue for potential fixes, such as using 'train model.train(model.docvecs.corpus count)' or similar. Verify if the fix involves adding a property or modifying the train method.
