Use it on custom dataset for regression task

[slimwangyue]

I have a custom dataset which contains lots of images. During the training the data loading seems to be the bottleneck. But the dataset does not have the classification label, while each image has a label which is a float value (not int). And the label information is stored in a text file in the following format. How can I use this tool to generate the LMDB file.
