distilbert-base-multilingual-cased-sentiments-student

This model is distilled from the zero-shot classification pipeline on the Multilingual Sentiment dataset using this script.

In reality the multilingual-sentiment dataset is annotated of course, but we'll pretend and ignore the annotations for the sake of example.

Teacher model: MoritzLaurer/mDeBERTa-v3-base-mnli-xnli
Teacher hypothesis template: "The sentiment of this text is {}."
Student model: distilbert-base-multilingual-cased

Inference example

from transformers import pipeline

distilled_student_sentiment_classifier = pipeline(
    model="lxyuan/distilbert-base-multilingual-cased-sentiments-student", 
    return_all_scores=True
)

If you are training this model on Colab, make the following code changes to avoid Out-of-memory error message:

###### modify L78 to disable fast tokenizer 
default=False,

###### update dataset map part at L313
dataset = dataset.map(tokenizer, input_columns="text", fn_kwargs={"padding": "max_length", "truncation": True, "max_length": 512})

###### add following lines to L213
del model
print(f"Manually deleted Teacher model, free some memory for student model.")

###### add following lines to L337
trainer.push_to_hub()
tokenizer.push_to_hub("distilbert-base-multilingual-cased-sentiments-student")
