Hi @patrickvonplaten , I have trained a model using wave2vec2 and tried to use n-gram with it. But there are errors like input shape is not matching. Also my model didn’t generate any alphabet.json file. I have tried your blog Boosting Wav2Vec2 with n-grams in 🤗 Transformers . But it didn’t worked on my model. Though it worked on some other models. Could you guide me what’s wrong with my model training? Here is my mode: nihalbaig/wav2vec2-large-xlsr-bn · Hugging Face .
