Research direction

Open dftio/data/init.py at the all definition linked in the issue. Run from dftio.data import * to reproduce the TypeError, then verify that all entries are string names, the duplicate feature_to_block is removed, and the wildcard import succeeds.

Written by the indexing model from the issue text.

Description

This issue comes from a Codex global repository scan.

Problem

dftio.data.__all__ contains imported objects instead of string names:

https://github.com/deepmodeling/dftio/blob/c9d128f24a74ef2911e1a28f5640357488beb196/dftio/data/__init__.py#L15-L29

Python expects every __all__ entry to be a string. As written, wildcard imports fail instead of exporting the public API.

Reproduction

Run:

from dftio.data import *

This raises TypeError: Item in dftio.data.__all__ must be str.

Suggested fix

Change entries to string names and remove the duplicate feature_to_block entry.
