 Thank you very much for sharing your code. It has been extremely helpful and inspiring. I appreciate your contributions to the development of PINN. 
 I have downloaded your source code and tried running the code related to the Viscous Burgers equation. However, I'm experiencing gradient explosions and ending up with NaN values for the loss when using the L-BFGS algorithm. Do you have any suggestions on how to address this issue?
