Error when running by config with a list of batch sizes

[tripl3a]

The config was like this:

"batch_size":                   {"value": [16, 32], "default": 48,  "desc": "Total batch size for training for single GPU v100. If using multiGPU, the total batch size will be automatically adjusted."},

Which lead to the following, somehow odd, error:

Hi @tripl3a, thank you for reporting the issue. It was a type error fixed by #41.
