Currently works with Tensorflow 1.7

TensorBox is a project for training neural networks to detect objects in images. Training requires a json file (e.g. here) containing a list of images and the bounding boxes in each image. The basic model implements the simple and robust GoogLeNet-OverFeat algorithm with attention.

OverFeat Installation & Training

First, install TensorFlow from source or pip (NB: source installs currently break threading on 1.2)

$ git clone
$ cd tensorbox
$ ./
$ cd /path/to/tensorbox/utils && python install && cd ..
$ python --hypes hypes/overfeat_rezoom.json --gpu 0 --logdir output
$ #see evaluation instructions below

Note that running on your own dataset should only require modifying the hypes/overfeat_rezoom.json file.

Training on your own data

TensorBox supports several data formats for bounding boxes description (idl, json, ...). The easiest way to fid your dataset is making a json-file description. It could be made using script or you can convert other annotation description into json. The file formats are described here.

Now you are able to change input size of image in hypes files. Make sure that it is multiple 32. Also a couple of experimental and not working models has been added recently.

ReInspect Installation & Training

ReInspect, initially implemented in Caffe,
is a neural network extension to Overfeat-GoogLeNet in Tensorflow.
It is designed for high performance object detection in images with heavily overlapping instances.
See the paper for details or the video for a demonstration.

 $ git clone     
 $ cd tensorbox        
 $ ./      
 $ # Download the cudnn version used by your tensorflow verion and         
 $ # put the libcudnn*.so files on your LD_LIBRARY_PATH e.g.       
 $ cp /path/to/appropriate/cudnn/lib64/* /usr/local/cuda/lib64     
 $ cd /path/to/tensorbox/utils && python install && make hungarian && cd ..      
 $ python --hypes hypes/lstm_rezoom.json --gpu 0 --logdir output      
 $ #see evaluation instructions below


Python script

The following instructions demonstrate how was used after one of my experiments - you will need to change paths as appropriate:

$ # kill training script if you don't have a spare GPU
$ cd /path/to/tensorbox
$ python --weights output/overfeat_rezoom_2017_01_17_15.20/save.ckpt-130000 --test_boxes data/brainwash/val_boxes.json
$ # val_boxes should contain the list of images you want to output boxes on, and
$ # the annotated boxes for each image if you want to generate a precision recall curve
$ cd ./output/overfeat_rezoom_2017_01_17_15.20/images_val_boxes_130000/
$ ls # ... notice the images with predicted boxes painted on, and the results saved in results.png
$ python -m SimpleHTTPServer 8080 # set up a image server to view the images from your browser
$ ssh myserver -N -L localhost:8080:localhost:8080 # set up an ssh tunnel to your server (skip if running locally)
$ # open firefox and visit localhost:8080 to view images


If you get some decent results and want to improve your performance, there are many things you can try. For hyperparameter optimization, the Learning rate, dropout ratios, and parameter initializations are a great place to start. You may want to read this blog post for a more generic tutorial on debugging neural nets. We have recently added a resnet version as well, which should work slightly better on larger boxes (this repo has historically done poorly on these, as they weren't port of the original research goal). I would recommend using the overfeat version over the lstm as well if you have a large variation in box sizes.


You can visualize the progress of your experiments during training using Tensorboard.

$ cd /path/to/tensorbox
$ tensorboard --logdir output
$ # (optional, start an ssh tunnel if not experimenting locally)
$ ssh myserver -N -L localhost:6006:localhost:6006
$ # open localhost:6006 in your browser

For example, the following is a screenshot of a Tensorboard comparing two different experiments with learning rate decays that kick in at different points. The learning rate drops in half at 60k iterations for the green experiment and 300k iterations for red experiment.
