OS: Ubuntu 18.04
nbqa version: 0.1.21
I have a notebook present in a directory which is not a python package. When i try to run the following command nbqa black <my_notebook_file>, I get a StopIteration exception traceback. I looked into the code and I was able to figure out why it is raising this exception.
def _create_blank_init_files(notebook: Path, tmpdirname: str) -> None:
parts = notebook.resolve().relative_to(Path.cwd()).parts
for idx in range(1, len(parts)):
# next on directory with no __init__.py raises StopIteration exception
init_file = next(Path(os.path.join(*parts[:idx])).glob("__init__.py"))
if init_file is not None:
Path(tmpdirname).joinpath(init_file).parent.mkdir(
parents=True, exist_ok=True
)
Path(tmpdirname).joinpath(init_file).touch()
I fixed the code locally and ran isort, black, flake8 and mypy. This is the fix I made locally
import contextlib
def _create_blank_init_files(notebook: Path, tmpdirname: str) -> None:
parts = notebook.resolve().relative_to(Path.cwd()).parts
for idx in range(1, len(parts)):
with contextlib.suppress(StopIteration):
init_file = next(Path(os.path.join(*parts[:idx])).glob("__init__.py"))
if init_file is not None:
Path(tmpdirname).joinpath(init_file).parent.mkdir(parents=True, exist_ok=True)
Path(tmpdirname).joinpath(init_file).touch()
Are you mandating the presence of __init__.py file in the directory of notebooks to run nbqa?
