The link referenced in the fast-rcnn readme file (https://github.com/NervanaSystems/ModelZoo/blob/master/ObjectLocalization/FastRCNN/readme.md) is broken:
https://github.com/NervanaSystems/neon/tree/master/examples/fast-rcnn is no longer present in the neon examples

The obsolete references from the readme file are:

The model scripts are part of the neon examples and can be accessed from this link to the
[neon repository](https://github.com/NervanaSystems/neon).  Specifically, the Fast RCNN example
readme and scripts can be found [here](https://github.com/NervanaSystems/neon/tree/master/examples/fast-rcnn).

The Fast RCNN scripts and [README](https://github.com/NervanaSystems/neon/blob/master/examples/fast-rcnn/README.md)
are located in the neon examples [directory](https://github.com/NervanaSystems/neon/tree/master/examples/fast-rcnn).

To measure the performance of the trained file (see above) using the Pascal VOC test data set, activate the
neon virtual env (if applicable) and run the following command from the neon repo root directory:
python examples/fast-rcnn/run_validation.py --model_file frcn_vgg.p

[DawnStone]

The fast-rcnn example has been replaced by the faster-rcnn example in the neon repo: https://github.com/NervanaSystems/neon/tree/master/examples/faster-rcnn
