I added the following parameter (hub_token) in the training_args as below :-
training_args = Seq2SeqTrainingArguments(
    output_dir="results",
    num_train_epochs=1,  # demo
    do_train=True,
    do_eval=True,
    per_device_train_batch_size=4,  # demo
    per_device_eval_batch_size=4,
    # learning_rate=3e-05,
    warmup_steps=500,
    weight_decay=0.1,
    label_smoothing_factor=0.1,
    predict_with_generate=True,
    logging_dir="logs",
    logging_steps=50,
    save_total_limit=3,
    push_to_hub=True,
    hub_token = 'token value'
)

but when I try to compile :-
trainer = Seq2SeqTrainer(
    model=model,
    args=training_args,
    data_collator=data_collator,
    train_dataset=train_data,
    eval_dataset=validation_data,
    tokenizer=tokenizer,
    compute_metrics=compute_metrics
)

FileNotFoundError: [WinError 2] The system cannot find the file specified
During handling of the above exception, another exception occurred:
File "C:\Users\abhay.saini\AppData\Local\Programs\Python\Python39\lib\site-packages\huggingface_hub\repository.py", line 489, in check_git_versions
    raise EnvironmentError(
OSError: Looks like you do not have git-lfs installed, please install. You can install from https://git-lfs.github.com/. Then run `git lfs install` (you only have to do this once).

I did then try installing git-lfs
pip install git-lfs
Requirement already satisfied: git-lfs in c:\users\abhay.saini\appdata\local\programs\python\python39\lib\site-packages (1.6)

but the error persists…
Can anyone help?
