I've briefly reviewed the PR and added comments. Could you please make revisions based on these comments? I haven't actually tested the proposed changes myself, so please verify whether they work as expected.

I fixed code based on your comment and I think all the pytest passed.
I would appreciate it if you could check my changes.

@HirokiYasuda03 Sorry for not seeing this PR for a long time.

Could you please change the following section of pyproject.toml from

[tool.rye]
managed = true
dev-dependencies = [
    "bdpy[dev]",
    "jupyter",
    "pytest",
    "pytest-cov",
    "ruff",
    "mypy"
]

to

[dependency-groups]
dev = [
    "bdpy[dev]",
    "jupyter",
    "pytest",
    "pytest-cov",
    "ruff",
    "mypy"
]

[tool.uv]
default-groups = ["dev"]

so that dev dependencies can be installed successfully via uv? I believe the remaining changes are fine, so I’d like to merge them as soon as this fix is reflected. Thank you

@ganow
I changed the pyproject.toml and uv.lock.
I think all the tests are passed, but test summery is not uploaded due to permission issue.

@HirokiYasuda03 thank you! But please not to include uv.lock since this repository is the package

[HirokiYasuda03]

@ganow
Sorry. I deleted the uv.lock.
