loss is descending,but the val loss=nan,anybody have face this problem?
Guys, i have such pproblem and i don't know what to do.It says that number mask dimensions is not specified? What is this and how to fix it Traceback (most...
when I run "python yolo_video.py --image", it loads model successfully. But then I input the name of test picture, error occurs as follows: ************************************************************************************************** Input image filename:1.jpg (416, 416, 3)...
hi. I've searched but didn't quite understand how I should create train.txt file. i have voc annotation files, in xml, and image's path, but i don't know how to combine...
Do anyone tried to convert trained .h5 model to Tensorflow Lite or Tensorflow Serving? I got some difficulties due to some python functions such as 'yolo_loss' and 'yolo_head'.
我在用视频测试yolov3时，速度只能达到最快十几帧，最少时只有几帧是什么情况啊，在其他地方搜集信息说是和darknet的Makefile有关系，请问这是什么情况啊
After training a model, and converting the model to tfjs, if I try to use the model in TFJS getting this error. Error loading layer ValueError: Unknown layer: Lambda. This...
Hello i trained yolov3 with this repo and converted to tensorflow js format with using tensorflowjs_converter. But when model loading it throw "Error: Unknown layer: Lambda. This may be due...
