Too long test time

[ppengtang]

Hi, I haven't met this problem before. I have asked my friends to help me test on their machines and the test time looks normal (2-3 hours to test on VOC 2007 test). Could you check whether you run multiple experiments on the same GPU at the same time?

Thanks you for your codes.
But I also encountered this problem.
My GPU is 3080, and the test time is also very very long(~36hours), while the training time is normal(~6hours).
My Pytroch version is 1.7.0 with CUDA 11.1(Nvidia Driver Version : 455.38).
And I used default setting. (Although I installed mmcv for CUDA 11).
Are this problem related to CUDA or driver version?
Thanks a lot.

Hi @MRRRKING @U201714643 , we have tested on V100 and 2080Ti GPUs. The testing speed looks reasonable (less than 3 hours on VOC 2007 test). Could you try to follow install.sh to set up environments? Could you also check the GPU utilization rate by nvidia-smi?

Yes, I followed the install.sh file. And the GPU utilization is 100%.
I try to set the parameter TEST.BBOX_AUG.ENABLED to False, and the testing time is normal(~2 hours).
I suspect the problem lies in the im_detect_bbox_aug function.

Do you have any direction to solve the problem?

That's weird. Sorry I don't have 1080Ti GPUs and thus cannot reproduce the issue. Could you try to record the time cost of each part in im_detect_bbox_aug and the time cost of each line in these codes?

In addition, if TEST.BBOX_AUG.ENABLED is set to False, the test time will be reduced by about 10x, so the reasonable test time should be less than half an hour.

Hi.
I think this line might lead to long test time:

blob_conv = self.Conv_Body(im_data).contiguous()

This is my way to measure its run time:

    torch.cuda.synchronize()
    start = time.time()
    ############################
    blob_conv = self.Conv_Body(im_data).contiguous()

Do you have any direction to solve the problem?

[ppengtang]

Could you try to add torch.cuda.empty_cache() after this line of codes? I'm not sure about the exact reason. I guess one possible reason is the GPU cache has not been released after testing each image.

[ppengtang]

Btw, could you also make sure to add CUDA_VISIBLE_DEVICES=0 at the beginning of the test command and do not use --multi-gpu-testing? There are some bugs in multi-gpu testing.

[MRRRKING]

I test the running time in this way:
` print(target_scale)
print('*************************************')
time4 = time()
return_dict = model(**inputs)
time5 = time()
print('time5: ', time5 - time4)
# cls prob (activations after softmax)
scores = return_dict['refine_score'][0].data.cpu().numpy().squeeze()

for i in range(1, cfg.REFINE_TIMES):
    scores += return_dict['refine_score'][i].data.cpu().numpy().squeeze()

scores /= cfg.REFINE_TIMES
# In case there is 1 proposal
scores = scores.reshape([-1, scores.shape[-1]])

time6 = time()
print('time6: ', time6 - time5)`

And the result is below:

I see. Maybe dilation 1 is the reason for performance drop.

From the test results, time is not spent on model prediction, but on data conversion.

pcl.pytorch/lib/core/test.py

Line 109 in 0896c82

scores = return_dict['refine_score'][0].data.cpu().numpy().squeeze()

I test the old codes which run on the pytroch 0.4.1 environment, and its testing time is normal.
Is it related to the pytorch version?

Could you try to change these codes to the following codes?

    scores = return_dict['refine_score'][0].squeeze()
    for i in range(1, cfg.REFINE_TIMES):
        scores += return_dict['refine_score'][i].squeeze()
    scores /= cfg.REFINE_TIMES
    # In case there is 1 proposal
    scores = scores.view(-1, scores.size[-1]).data.cpu().numpy()

I don't think the issue is from pytorch version. On my GPUs, I could get correct results using pytorch 1.6.0

I replaced these codes, but it didn't work.
The testing time is normal with dilation 1, but the mAP is lower too.

Are you using pytorch 1.7.0 or 1.7.1？

Hello, I meet the same problem in the test.
I use gtx1080ti, pytorch 1.6.0
but I made the following changes in install.sh:
①pip --no-cache-dir install mmcv-full==latest+torch1.6.0+cu101 -f https://openmmlab.oss-accelerate.aliyuncs.com/mmcv/dist/index.html
Change to
pip install mmcv-full -f https://download.openmmlab.oss.com/mmcv/dist/cu101/torch1.6.0/index.html (according to the official)
(because I always report mistakes in the original method)
②pip --no-cache-dir install numpy==1.16.0
Change to pip -- no cache dir install numpy==1.19.5
(for the reason when trying to solve the problem of mmcv, the environment always downloads 1.16.0 first, then automatically deletes it and uses 1.19.5.)
After that, training for 13 hours is normal, and the test showed that it was expected to be 6 days.
I don't know if these will lead to problems in the test.

Could you also try to add torch.backends.cudnn.enabled = False after this line of codes for dilation=2? Other people observed a similar issue of low speed of dilated convolution on some GPU cards: https://discuss.pytorch.org/t/speed-drop-with-dilated-conv-on-different-gpus/82412

No, I use pytorch 1.6.0.

Thanks for your advice.
It works.
Now mAP is 51.7%, and CorLoc is 68.2%.(Model is trained with with dilation 2)
In addition, testing time is about 80 minutes.
Besides, VRAM usage ranges between 7500MB and 9500MB, which is more than testing with cudnn.

It works. Thanks a lot.
Now the testing time is about 2.5 hours, and mAP is 51.9.

It works. the testing time is normal about 2h24min,
Mean AP = 0.5231

Hi,
Did you re-train your model with cudnn disabled?

[ppengtang]

Great! Thanks for helping to debug! It is unnecessary to re-train the model with cudnn disabled. Btw, you could try different random seeds (1~10) by changing cfg.RNG_SEED to reproduce the reported numbers.

i just add "torch.backends.cudnn.enabled = False" in test_net, and all other codes are default

您是否还可以尝试在这行代码torch.backends.cudnn.enabled = False之后添加膨胀= 2？其他人在某些 GPU 卡上观察到类似的扩张卷积速度低的问题：https ://discuss.pytorch.org/t/speed-drop-with-dilated-conv-on-different-gpus/82412

谢谢你的帮助！ 有用。测试时间正常约2h24min， 平均AP = 0.5231

您好！请问您知道怎么可视化检测结果吗？
