Please kindly help us about Not convergent network #12
Comments
@yaoanderson thank you very much for this issue... please git pull to get few changes I found thanks to your issue... and then I would recommend burn_in=10 not 1000... and please let me know if that is better :D... I tested and it should be :D. thanks again! |
thanks so much sowson, I will try now and give your feedback for this problem. |
Hi @sowson , I continue to train my network by using the newest code (git pull and cmake and make) and burn_in=10 now. By the way, can I continue to train my network based on the training result by old code from round 960 like as above screenshot ? Or I just retrain my new network based on your new code from round 1 ? |
Hi @sowson, your code based on opencl: Could you please speed up your code based on opencl ? : ) |
Hi @sowson thanks for your reply. This is my PC hardware config. Is it different from your PC ? Do you have any idea about my PC or run cmd ? |
wow! :D check this out: add -i 1 (index of your gpu 0 is intel, 1 is radeon) :D |
The default option is to use 0 intel ? right ? |
@sowson Another questions:
|
That is correct. |
I wish I knew what anchors value means :D |
Hi @sowson I solve it, yolov2 set < 13 is ok. Very nice thanks so much for your help. :) |
Hi sowson,
We used your darknet network which running in our Macbook Pro Opencl, but so weird about our training based on your code, and it seems to be Obj: 0.500000, No Obj: 0.500000 all the time for hundreds circle training. And training is not convergent all the time.
Our data is from https://timebutt.github.io/static/how-to-train-yolov2-to-detect-custom-objects/ this article dataset.
network as below:
my yolov2.cfg as below:
