RuntimeError: received 0 items of ancdata

[JaheimLee]

When using prepare.sh file in wenetspeech from stage 1, a runtime error raised during computer features of data/fbank/cuts_TEST_NET_raw.jsonl.gz. Here is the logs:

2022-08-02 22:39:27,066 INFO [compute_fbank_wenetspeech_dev_test.py:63] Loading data/fbank/cuts_TEST_NET_raw.jsonl.gz

And when Computing features in batches: 16024it, it will raise:

I got the same error, and resolved by suggestions in https://discuss.pytorch.org/t/runtimeerror-received-0-items-of-ancdata/4999
