Results isssue

[Maryam483]

Hai, I have trained supervised model just like steps you give (step 1-4), after training supervised baseline model on COCO dataset, I have run semi_dest.sh with corresponding file paths to determine performance of supervised model, and the performance is 12% ( I have used 10% as partially labelled data) but in Table 1 of your paper the result is "23.70 ± 0.22". How I solve this issue??

Secondly, I am training model on 1 GPU device. This is the only difference.

I am waiting for your positive response and guidance please. Thanks.

Learning rate and running epochs might be adjusted for different GPU numbers.

I did not understand should I kept learning rate low or high, with one GPU device???? Because, I have result of 12% and your results is 23%. I have added code of config file below? Please tell me which parameters should I tune??? Secondly, does GPU devices matter in achieving same performance like you used 8 GPUs, but i have used 1 GPU.??

@Maryam483 Sorry, I didn't test on 1 gpu. So I cannot tell you how to change the value. You can try by your self, good luck~

[Maryam483]

The semi-supervised model requires 158 days on my "1 GPU device" . Why??

You have used 8 GPUs but I have 1 GPU device.

I have "Titan XP (12GB VRAM) GPU with 16 GB RAM". I have added screenshot below.

[chenbinghui1]

@Maryam483 ; Please check (1) Whether moving model to GPU for computing

If yes, emm, you can change a task. Titan Xp might not be good for detection task.

I use 8 NVIDIA-V100 for training
