Hi Jianming Zhang, Manting Huang, Xiaokang Jin and Xudong Li,

I enjoyed reading your paper and I am impressed with the good work. My issue is this, when I use five anchor boxes, it works perfectly. When I use eight anchor boxes, after 250+ steps I experience NaNs. Have you experienced this? Do you have any understanding about why this could be occurring?

Thanks,

Trent

Hey, I actually was implementing Yolo for Traffic Sign Detection using LISA Dataset but it turns out that the dataset is fit for faster RCNN model. Can you please provide the annotations for YOLO model?

Hello, in the lisa.data file we can see that we have number of classes which is 6, but for the whole LISA data set of the traffic sign, we have 47 different type of the traffic signs. This information is from the categories.txt file of the LISA traffic sign dataset. Did you filter out the type of signs that you don't need? Would you mind provide more information about what are the traffic signs that you used for training? thank you.

Would be really useful if you added the accuracy of your trained model. Thanks! 😃

I have some questions about how to use the python tool to get the dataset format that we can use. In the lisa.names file we find there were 5 labels that we need:speedLimit, warning, noTurn, stop, pedestrianCrossing, signalAhead. I assume we need to use the extractAnnotations.py to get those annotations for the training and here is what I did
`:~/Desktop/CUelectrical car/DATASET/tools$ python extractAnnotations.py -c [speedLimit, noTurn, stop, pedestrainCrossing, signalAhead]

usage: extractAnnotations.py [-h] [-f acceptedTag] [-c category] [-m 5]
{copy,mark,blackout,crop} filename.csv

extractAnnotations.py: error: argument mode: invalid choice: 'noTurn,' (choose from 'copy', 'mark', 'blackout', 'crop')
`
Can you help me to find the way that I can convert the dataset into the format that I need? thank you!!

hi,
I searched for the whole project but can't find the weight file. Could you pls tell me where can I download the file, thanks.

Hi,
Can you share the LISA weights?

./darknet detector train cfg/lisa.data cfg/yolo-lisa.cfg darknet19_448.conv.23

Excuse me, i am new to YOLO, am i doing right?
It prompts me an error with "Couldn't open file: LISATS/train/train.txt".
