Questions for trainning on University-1652

[nono-zz]

Hi,

I directly trained the model to match images from two views (satellite -> drone) through the 'train.py', but the accuracy remained extremely low (from 0.0000 to 0.0060), and didn't grow with epoch increases.

I changed some of the parameters for training on my computer, the changes are as follow:
batchsize = 2
num_workers = 0
inputs2, labels2 are from the 'drone' directory
LPN = True

I wonder how I could achieve the accuracy. Are there any preparations upon the dataset needed before training? Thank you very much for your help!

Hi，
I do not know whether you have set opt.views=2. If you want to training and testing using two view (satellite->drone), you can refer to this link layumi/University1652-Baseline#12 (comment).
In short, you need to set opt.views=3 and change the loss weight of street view （street and google） to 0 when training.

Also, if you change the batchsize, you need to re-adjust the learning rate.

Hi,
Thank you very much for your prompt reply! I changed the opt.view from 2 to 3, and then adjusted the learning rate according to the batchsize. The result turned out to be great!
