Custom Data Layer Error #42

Hi,

I am trying to use different data than you have used in your experiment. So I have used CustomData and slicing points. The network read all the data and the sizes of each record. For example :

I0705 15:18:15.431681 162296 custom_data_layer.cpp:541] output 0 data size: 8,3,384,512 I0705 15:18:15.431759 162296 custom_data_layer.cpp:541] output 1 data size: 8,3,384,512

After that I have got the following error:

I0705 15:18:15.516582 162296 net.cpp:145] Setting up CustomData-M F0705 15:18:15.516605 162307 custom_data_layer.cpp:184] Internal data fetch error: Tried to fetch element 0 of 6999 which is in DB: 5521

5521 is the first record before slicing in the LMBD.

The question is: since the network is reading all the input data and can determine the size and the number of channels , why this error is showing?

Thanks

Closing due to inactivity; I think we cannot help with this issue. It looks a problem either in LMDB or the CustomData layer, neither of which are ours.
