Error while running convert script

I got the following error while running the convert script:

./convert.sh

I deleted the file "trainval.txt" and just by then it worked and created a directory under the name of "trainval.txt" !!
This is strange, have I did something wrong?

[WinfredHuang]

It is strange. I've found similar problem when creating LMDB.

[mohanadkaleia]

But even though the created lmdb is empty, my mistake because the directory of the training set was wrong in my case, so I fixed it then it went fine,
Just double check the configuration for the convert file

Problem solved...
It seems "mkdir" (as a C function) cannot automatically create multiple layers of directories. @yeahkun See if you can fix this problem.

[WinfredHuang]

I've found solution on Issue #6 .Please close this issue @yeahkun .

I think @AurusHuang is right
Problem solved...
The command line is
./build/tools/convert_imageset kodak_noisy/image/ kodak_noisy/kodak_noisy.txt ./lmdb
