Hi. I fine-tuned 4 Wav2Vec2 models with different settins, following by letter this guide 2. After I finished training, I saved the models using model_name.save_pretrained(PATH). After saving, I immediately loaded the model to see if it works properly, and it worked.
Today, I wanted to check something and I loaded one of the models again, and I saw that it can predict nothing. Every prediction is wrong. The characters it predicted are indeed from my vocabulary, but they are just…random. I have no idea what is going on. I also do not know what else to post here to give you more information. I followed the guide I linked above exactly, only thing I changed is that I saved my models. The loaded models worked yesterday! Today they do not.
The models are loaded as model = Wav2VecForCTC.from_pretrained(PATH).
Inside path, there are the following files: (1)config.json, (2)pytorch_model.bin and (3) training_args.bin. Note that the last one was saved manually by me (the training args).
Does anyone have any idea what might be happening? Please, any help is appreciated, as this is important to me… Thanks in advance.
