Error when running install script example: `Placeholder storage has not been allocated on MPS device!`

[jaanli]

After running this:

from melo.api import TTS

# Speed is adjustable
speed = 1.0
device = 'cpu' # or cuda:0

text = "我最近在学习machine learning，希望能够在未来的artificial intelligence领域有所建树。"
model = TTS(language='ZH', device=device)
speaker_ids = model.hps.data.spk2id

output_path = 'zh.wav'
model.tts_to_file(text, speaker_ids['ZH'], output_path, speed=speed)

From the instructions: https://github.com/myshell-ai/MeloTTS/blob/main/docs/install.md

This error results:

Does anyone else experience this? Any tips on debugging?
