Did you update of the registered coco dataset? And what parameters and its values, you used in config file? |
The following are the parameters we used in training without any modification. I don't quite understand what you mean by "the registered coco dataset" /root/anaconda3/envs/detectron2/bin/python3.6 /jmx/centermask2/train_net.py --config-file configs/centermask/centermask_lite_V_19_eSE_FPN_ms_4x.yaml --num-gpus 4 sys.platform linux PyTorch built with:

@jiameixia1202 I mean by "the registered coco dataset" you use coco dataset not custom dataset. You can debug and check the pre_nms_top_n value in ''centermask/modeling/fcos/fcos_outputs/'
When cfg.SCORE_THRESH_TEST = 0.05 then self.pre_nms_thresh = 0.05. This value may cause of make pre_nms_top_n empty and make zero accuracy. So, check if pre_nms_top_n is tensor([0, 0] or not. |
I use the registered coco dataset, and I check the pre_ nms_ top_ n is tensor([0, 0] . It is normal for me to test with the weight provided by you, but when I train myself, the accuracy is 0 (without modifying the network, data and parameters) |
cfg.SCORE_THRESH_TEST = 0.05 then self.pre_nms_thresh = 0.05 How do I modify these two parameters? |
You can modify it through config file ''configs/centermask/centermask_lite_V_19_eSE_FPN_ms_4x.yaml' under MODEL and FCOS. If FCOS not exist, add it and modify the value 0.05 of INFERENCE_TH_TRAIN and INFERENCE_TH_TEST. Like this: |
I'm sorry, there may be something wrong with what I just said, |
can we change the optimizer to Adam? |
My server does not have 8 GPUs. When I use 4 GPUs for training (without any modification to the network), I just change num-gpus to 4. After training, the segmentation accuracy is always 0.00. Do you need to modify other parameters?
