GitHub issue #4769: Fail to process SQuADv1.1 datasets with max_seq_length=128, doc_stride=96.
State: open | Created: 2022-07-29T11:18:24Z

## Describe the bug
datasets fail to process SQuADv1.1 with max_seq_length=128, doc_stride=96 when calling datasets["train"].train_dataset.map().

## Steps to reproduce the bug

I used huggingface[ TF2 question-answering examples](https://github.com/huggingface/transformers/tree/main/examples/tensorflow/question-answering). And my scripts are as follows:

```
python run_qa.py \
  --model_name_or_path $BERT_DIR \
  --dataset_name $SQUAD_DIR \
  --do_train \
  --do_eval \
  --per_device_train_batch_size 12 \
  --learning_rate 3e-5 \
  --num_train_epochs 2 \
  --max_seq_length 128 \
  --doc_stride 96 \
  --output_dir $OUTPUT \
  --save_steps 10000 \
  --overwrite_cache \
  --overwrite_output_dir \

```

## Expected results
Normally process SQuADv1.1 datasets with max_seq_length=128, doc_stride=96.

## Actual results
```

WARNING:datasets.fingerprint:Parameter 'function'=<function main.<locals>.prepare_train_features at 0x7f15bc2d07a0> of the transform datasets.arrow_dataset.Dataset._map_single couldn't be hashed properly, a random hash was used instead. Make sure your transforms and parameters are serializable with pickle or dill for the dataset fingerprinting and caching to work. If you reuse this transform, the caching mechanism will consider it to be different from the previous calls and recompute everything. This warning is only showed once. Subsequent hashing failures won't be showed.
