Contents of lmdb. The file structure is:

├── data.mdb

The data.mdb and lock.mdb are standard lmdb files and you can refer to
https://lmdb.readthedocs.io/en/release/ for more details.
The meta_info.txt is a specified txt file to record the meta information
of the datasets. Each line in the txt file records 1)image name
(with extension), 2)image shape, and 3)compression level, separated
by a white space.
For example, the meta information could be:
`000_00000000.png (720,1280,3) 1`, which means:
1) image name (with extension): 000_00000000.png;
2) image shape: (720,1280,3);
3) compression level: 1
The image name is used without extension as the lmdb key.
Args:
data_path (str): Data path for reading images.
lmdb_path (str): Lmdb save path.
img_path_list (str): Image path list.
keys (str): Used for lmdb keys.
batch (int): After processing 'batch' number of images, lmdb commits.
Default: 5000.
compress_level (int): Compress level when encoding images. Default: 1.
map_size (int | None): Map size for lmdb env. If None, use the
estimated size from images. Default: None
