ValueError: Mixed precision training with AMP or APEX (`--fp16`) and FP16 evaluation can only be used on CUDA devices

I am trying to tune Wav2Vec2 Model with a dataset on my local device using my CPU (I don’t have a GPU or Google Colab pro), I am using this as my reference. When I try to execute

from transformers import TrainingArguments

training_args = TrainingArguments(
  # output_dir="/content/gdrive/MyDrive/wav2vec2-base-timit-demo",
  output_dir="./wav2vec2-medical",
  group_by_length=True,
  per_device_train_batch_size=32,
  evaluation_strategy="steps",
  num_train_epochs=30,
  fp16=True,
  save_steps=500,
  eval_steps=500,
  logging_steps=500,
  learning_rate=1e-4,
  weight_decay=0.005,
  warmup_steps=1000,
  save_total_limit=2,
)

I am getting following error:

ValueError: Mixed precision training with AMP or APEX (`--fp16`) and FP16 evaluation can only be used on CUDA devices.

I understand that the error is because I am not using a GPU, as mixed precision can not be carried out without a GPU. I want to run it on my CPU, how can I resolve the error

You should remove fp16=True then.
