A Reader that outputs the records from a LMDB file.

## Summary


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />


Optional attributes (see
`
https://www.tensorflow.org/versions/r2.5/api_docs/cc/struct/tensorflow/ops/l-m-d-b-reader/attrs#structtensorflow_1_1ops_1_1_l_m_d_b_reader_1_1_attrs
`
):

- container: If non-empty, this reader is placed in the given container. Otherwise, a default container is used.
- shared_name: If non-empty, this reader is named in the given bucket with this shared_name. Otherwise, the node name is used instead.

<br />


Returns:
