Training hyperparameters

Result can be reproduce using the following commands:

bash

python transformers/examples/research_projects/zero-shot-distillation/distill_classifier.py \
--data_file ./multilingual-sentiments/train_unlabeled.txt \
--class_names_file ./multilingual-sentiments/class_names.txt \
--hypothesis_template "The sentiment of this text is {}." \
--teacher_name_or_path MoritzLaurer/mDeBERTa-v3-base-mnli-xnli \
--teacher_batch_size 32 \
--student_name_or_path distilbert-base-multilingual-cased \
--output_dir ./distilbert-base-multilingual-cased-sentiments-student \
--per_device_train_batch_size 16 \
--fp16

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

bash

###### 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")
