How to set the value of "multfact" in HeatmapDataParameter? #1

Closed fengyang0317 closed 8 years ago

fengyang0317 commented 9 years ago

The value is 0 by default. However, it is multiplied and divided by some some other value in data_heatmap.cpp, leading to nan error.

Hi fengyang0317, are you still using this code? I'm having difficulty in using the heatmap-Caffe, and a lot of strange errors came up when I want to run the .sh file. Could you tell me the version of your CUDA? I want to know if that matters. Thx!

Hi Feng, The default value of multfact should be 1 (it is a multiplication factor for the regression coordinates in your label file). This has been fixed in the latest commit.

I'm having the same error please; and I couldn't find a solution. What I want to know is how to set the value of "multfact" please ?? because in the readme file, is said that "Note these files require multfact=282 in both training and testing data layers": mean that the images have to have mulfact=282 and @tpfister you said that the dafault value is 1? Can you explain me that please ;

fengyang0317 commented 8 years ago

Hi, If you are using Pfister's data, you should set multfact to 282. If you prepare data yourself, it should be 1.

Pfister's data is transformed using the value 282.

I prefer to use fengyang0317@gmail.com.

Thanks @fengyang0317. So I have to add this variable "multfact" in the "train_val.prototxt" file , and set it to 282, isn't ?

fengyang0317 commented 8 years ago

yes，if you want to use his data.
