hdf5/group.lua:88: attempt to concatenate 'int64_t' and 'string'hdf5/

[agilebean]

Hi,
after training a model by

python scripts/make_style_dataset.py \```
  --train_dir ~/packs-fns/train \
  --val_dir ~/packs-fns/valid \
  --output_file dataset1.h5

I train the model by

th train.lua \
  -h5_file dataset1.h5 \
  -style_image ~/packs-fns/train/wisegeek.jpg \
  -style_image_size 384 \
  -content_weights 1.0 \
  -style_weights 5.0 \
  -checkpoint_name checkpoint \
  -gpu 0

This throws the following error message I am unable to understand:

/home/rstudio/torch/install/bin/luajit: /home/rstudio/torch/install/share/lua/5.1/hdf5/group.lua:88: attempt to concatenate 'int64_t' and 'string'

I couldn't find any hint by googling so I'm getting desperate.
Any ideas or hints??
