Hi,

Hi, I was training and.... nan..nan,

maybe you can reduce the learn_rate first, if it doesn't work, try to look for errors in your code and datasets?

@juanmanuelrq Have you solved this problem? I'm training VOC dataset, I got test loss = NAN, but train loss equals to sth. reasonable.

This indicates that you have a problem with train txt file what format are using ? it should be Filepath x1,y1,x2,y2 no headers @llmpass @juanmanuelrq

Train loss: nan Test loss: nan，This happened to me at the beginning of training，but the format of train.txt is same as you said

@juanmanuelrq Have you resolved the issue?

I have the same problem.

I am training one class and dataset is about 7000 images.

I read the following issues and solved the problem https://github.com/YunYang1994/tensorflow-yolov3/issues/294 https://github.com/YunYang1994/tensorflow-yolov3/issues/350 https://github.com/YunYang1994/tensorflow-yolov3/issues/170 https://github.com/YunYang1994/tensorflow-yolov3/issues/149

@qncsn2016 Thank you so much.

hello，I ran into the same problem and wanted to reinitialize the VOC dataset instead of training on the basis of Coco's pre-training weights.Test_loss =nan was the first epoch when I retrained VOC. How did you solve the problem?Thank you very much
