Thanks for your question. That's a bug due to a recent update. Now it should be fixed. Could you please pull the update and try again?
from squeezedet.
It works now. On speed performance, I found SqueezeDet is slower than tiny-yolo model of Darkflow on afirefly-3399 platform: SqueezeDet: 0.9138s/image vs Tiny-Yolo: 0.6s/image.
This is a surprise to me as I expect SqueezeDet should run faster.
Thanks,

This measurement is from demo.py. The time is measured below:
t_start = time.time()
det_boxes, det_probs, det_class = sess.run(
[model.det_boxes, model.det_probs, model.det_class],
feed_dict={model.image_input:[input_image]})
t_end = time.time()
times['detect'] = t_end - t_start
Firefly-3399 has 2 A72 core running at 2Ghz and 4 A53 cores (??Ghz). Tensorflow version: 1.0.1

I have converted VOC2012 datasets to KITTI format required by squeezedet.
Training is running OK, but converge is very slow if I keep original image size 1248x384 in kitti_squeezeDet_config.py
The issue of aspect ratio is quite distorted. If I change image size to 480x384, I got the following error during training:

Any other files should I change in order to to use this new image size?

@kaishijeng Could you share you scripts to convert VOC to KITTI format?
from squeezedet.
Here is what I did:
- Follow Training YOLO on VOC in https://pjreddie.com/darknet/yolo to download Pascal VOC dataset.
- Use my modified voc_pascal_new.py (below) to generate squeezeDet format of label.

I wonder how you fix the problem in _add_interpretation_graph @kaishijeng
