How to take points in the field?

[Fankunkun123]

Hello, sorry to bother you. I am currently experiencing the following issue when reimplementing the code for deepXDE: After taking points in the domain, how do I extract all the points "train_x" in the domain, boundary, and initial conditions? I hope you can help me answer this question. Thank you!

Use data.num_bcs

Hello, Dr. Lu. First of all, thank you very much for answering my question, which has been solved very well. Thank you.

I used the data.train_points() method to retrieve the training points, which is all the training points(including boundary points, initial points and in-domain points).
