Order of losses

[shanmukhi1998]

Hi.
Can anyone please clarify what is the order of losses that are displayed after every set of iterations?
Step Train loss Test loss Test metric
0 [2.63e+12, 6.19e-02] [2.64e+12, 6.19e-02] []
1000 [4.98e+07, 5.10e-02] [4.20e+07, 5.10e-02] []

In the above case, the first one is PDE loss or the second one?

Any help appreciated. Thanks.

See FAQ Q: What is the output of DeepXDE? How can I visualize the results?

Hi @lululxvi ,

Looking through the FAQ Q, referenced, I found info on train.dat but not loss.dat. Could you explain the contents of loss.dat? I noticed that the number of elements in loss.dat is the same as the number of equations plus the number of IC_BC

Also how to the write a loss.dat while the training is going on and has not yet finished?
