Issue with build_coordinates.py

Hello, I installed ffn and downloaded the sample data without issue. I am trying to train the sample model and got an error.

I ran this:

> (ffn) user:~/ffn-master$ runffn.sh
> #!/bin/bash
> python compute_partitions.py \
> --input_volume ~/third_party/neuroproof_examples/validation_sample/groundtruth.h5:stack \
> --output_volume ~/third_party/neuroproof_examples/validation_sample/af.h5:af \
> --thresholds 0.025,0.05,0.075,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9 \
> --lom_radius 24,24,24 \
> --min_size 10000
> python build_coordinates.py \
> --partition_volumes ~/third_party/neuroproof_examples/validation_sample/af.h5:af \
> --coordinate_output ~/third_party/neuroproof_examples/validation_sample/tf_record_file \
> --margin 24,24,24
>

compute_partitions.py runs fine, but with build_coordinates I get this:
