Hi,

I noticed in my experiments, that convert_imageset (lmdb) is using a GPU if available. At the moment I am compiling a imagenet sized dataset and it is using ~90MB on the GPU. I looked into the code and could not find why it would do so, as the image processing is done using opencv. Any idea what the reason could be?

Thanks
Ludwig

Still looking for an explanation. Here is the output of nvidia-smi:
