Hello all, I have two columns of data which I have loaded as a df and then dfs for training_set, testing_set, and a val_set. I keep getting the error posted below. I’ve tried resetting indexes, reindexing… Any ideas? Thank you very much!
The code block is:
training_args = Seq2SeqTrainingArguments(
output_dir=“TESTING”,
evaluation_strategy=“epoch”,
learning_rate=2e-5,
per_device_train_batch_size=16,
per_device_eval_batch_size=4,
weight_decay=0.01,
save_total_limit=3,
num_train_epochs=2,
fp16=True,
predict_with_generate=True,
)
trainer = Seq2SeqTrainer(
model=model,
args=training_args,
train_dataset=train_set,
eval_dataset=val_set,
tokenizer=tokenizer,
data_collator=data_collator,
compute_metrics=compute_metrics
)
trainer.train()
The error is:
