Environment

• OS: Ubuntu 22.04.1 LTS
• Python Version: Python 3.10.6
• Whispering version: whispering.git@v0.5.0

[shirayu]

Thank you for the report.
It seems that the poetry in your environment is older than expected.

I set the poetry-core version explicitly (b12ca01) and released v0.5.1.
Please try again with v0.5.1.

pip install -U git+https://github.com/shirayu/whispering.git@v0.5.1
