运行pre.py时出错，是虚拟内存的问题么？

运行pre.py时 报错，
F:\mockingbird\MockingBird-main\MockingBird-main>python pre.py H:/data -d aidatatang_200zh -n 4
Using data from:
H:\data\aidatatang_200zh\corpus\train

MemoryError

Reproduce the command from the issue, then inspect encoder/audio.py at trim_long_silences and synthesizer/preprocess_speaker.py at _process_utterance, where the traceback ends in MemoryError. Confirm the cause and document a reproducible resolution or clearly scoped change, with preprocessing completing successfully on the reported dataset.
