I suggest you check your trainval.txt and test.txt

[19931991]

Thanks for your reply , I try to generate the trainval.txt and test.txt ｆollowing the online tutoria . l think my trainval.txt and test.txt are right .And this is my trainval.txt :

Looking forward to your reply! @MhLiao

It seems that there is no error in your scripts. How about the source of the soft connection? The true data should be in "$data_root_dir/$dataset_name/$db/"

[19931991]

Thanks for your reply , my lmdb is

and my soft connetection is

I do not know how to debug , please help me ! @MhLiao

@19931991 I can not find the mistakes. Can you create Pascal VOC data successfully?

[19931991]

Yes, I create Pascal VOC data successfully , besides, I download the voc2007 and voc2012 , and when I run create_data.sh to create lmdb data ， it still did not succeed , the result is the same as my description - only empty soft connection. Can you tell me What environment is needed in create the lmdb ? Besides , I try to use other's lmdb (Target detection rather than text recognition) to train the network . the network runs up normally. In other words, if my data of lmdb is maked successfully , my work is done . So there is some wrong with my environment and cause this result ? Thank you very much !

Can I create lmdb in other computer , and copy to my computer to use it ? @MhLiao

[MhLiao]

Yes, you can.
