About demo test about netvlad HOT 4 CLOSED

Hi,
The code is trying to create the file and write features to it. I'm not exactly sure because of Chinese but it seems it fails at fopen in write mode, or fails to write to the opened file. Are you sure you have disk space and write permission to the folder you are trying to write to? Maybe you didn't set up the outPath correctly? I don't know if matlab has some issues with non-unicode characters, though nobody complained about that so far.

I think it fails because there is not a file called vd16_tokyoTM_conv5_3_vlad_preL2_intra_white_tokyo247_db.bin, this file is be created by the code "dbFeatFn= sprintf('%s%s_%s_db.bin', paths.outPrefix, netID, dbTest.name);",which in the demo.m
I don't find the introduction about this file. So should I proactively create this file manually in the corresponding path？

dbFeatFn= sprintf('%s%s_%s_db.bin', paths.outPrefix, netID, dbTest.name) doesn't create the file, it makes the name of the file. This file is then being created by the serialAllFeats function. This line in the function creates the file and opens it for writing, and this line tries to write to it.
I just noticed your log says the line fwrite(fout, buffer(:, 1:numInBuffer), class(buffer)); is number 79 while it is actually line number 81 in the original file - did you delete some code?

Ok, thinks , I think it's probably I don't give the permission to create the new folder. Thank you very much.
