AttributeError: module 'dtw' has no attribute 'stepPattern'

[ivanVgusev]

Code:

import whisper_timestamped as whisper
import json

audio = whisper.load_audio("/content/1_16bit.wav")

model = whisper.load_model("tiny", device="cpu")

result = whisper.transcribe(model, audio, language="ru")

word_timestamps = ''
for segment in result['segments']:
for word in segment['words']:
word_timestamps += str(word) + '\n'
print(word)

with open('res_.txt', 'w') as f:
f.write(word_timestamps)

I get an error on the line (result = whisper.transcribe(model, audio, language="ru"). It says AttributeError: module 'dtw' has no attribute 'stepPattern'. What could this mean?
