 60 和 75 轮会降learning rate

应该是正常的

但都已经训练了30多个Epoch了,rank@5还不到90%,这也正常吗??

@郑博士 你好。我这边运行train+virtual数据集,当运行到40个Epoch的时候,太慢了,我把它停了,然后跑测试集,但结果rank@5才不到90%,mAP才0.35,这正常吗??会是哪里出错了呢??

你有这个比赛的数据集吗?

@layumi 郑博士,我用真实数据集(也就是400个目标)进行训练,把80个Epoch都跑完了,但是mAP仍是只有0.47,请问这正常吗?

@s20163081161
是的。差不多。因为我validation用的gallery比较大。
之后你可以尝试post processing之类的,继续提升。

关于您所说的“gallery比较大”,我看您这里边的gallery是36900多张图片,那么多大的数量算大呢??有没有个衡量便准啥的??

您好@s20163081161,请问您跑的测试集是怎么制作的?我看readme只讲了训练集的制作。谢谢!

您好@s20163081161,打扰了,我在网上申请并得到了所有数据集。您说的mAP的测试代码是submit.py还是test_2020.py?

@layumi @s20163081161
I am running test_2020.py and as @layumi has mentioned earlier I am going to use val for test.
But how could I use val as a test dataset?
Should i split it to gallery and query?
Should I use val dataset as gallery or both gallery and query?

@s20163081161 test_2020 is to verify the effectiveness of the model on validation ( no offical valid set, so I splitted ). The final test result is obtained by the submission to the official test website.

@martianvenusian
Test set is provided by the offical aicity organizer. If you want to verify the final result, please run submit_result.py.
But they do not provide valid set, so I splitted the set to verify the model by using test_2020.py

@layumi Thank you for your support.
I have split val set to gallery and query as following if it is right way:

val/000341/
-- 000341_c010_7.jpg
-- 000341_c016_11.jpg
-- 000341_c017_5.jpg

query/000341/
-- 000341_c010_7.jpg

gallery/000341/
-- 000341_c016_11.jpg
-- 000341_c017_5.jpg

你好,我想问一下在prepare_2020.py中生成的gallery这个文件夹,prepare_2020.py并没有向里面添加图片,但是在后面大量用到,这个文件夹是用来做什么的,谢谢
