evaluate error

[geekvc]

th demo.lua goes well
when I run the evaluate:
model=data/models/caffenet_fast_rcnn_iter_40000.t7 ./scripts/eval_fastrcnn_voc2007.sh
model=data/models/vgg_fast_rcnn_iter_40000.t7 ./scripts/eval_fastrcnn_voc2007.sh
or
test_nGPU=4 test_nsamples=5000 ./scripts/eval_coco.sh
I got the similar error
