Hi,sir.
It confused me a lot that if I change 'stacked' to True, error happens:
Traceback (most recent call last):

Hi Prof. Lu,
Thank you for providing the code for the experiments!
I'm trying to run the models on the Burgers' equation, but I get errors on the PyTorch and TF sides.
For example, when runni…

Hello Prof. @lululxvi
Thank you for putting together DeepXDE. I was trying to run the Burgers code with a PyTorch backend however got a variety of errors. The first one was in the following lines

Hello, I have the following questions:
1. What version of Jax are you using?
When I ran PI_DeepONet_DR, I found that index_update and index were deprecated in newer versions of Jax, and optimizers…

The tests don't seem to cover the use and training of the operators, just a few properties. It would be good to get a few integration tests.

你好!
我在40G的A100卡上训练您的burgers方程的deepONet.py文件时,报错oom:

Hi Lu,
I am running your code for example of darcy_rectangular_pwc. I note that in your paper, you used hard constraints, as mentioned, "We use the coefficient 20 such that 20x(1−x)y(1−y) is of ord…

Hi,
I am trying to get the residuals during/after training a DeepONet.
Using the same approach that works in the "standard" PINN case
`residuals = np.absolute(self.model.predict(x, callbacks=..…

Great job! I wish that I had seen this earlier.
I would like to recommend

Hi, thank you for your nice work and code!
I have a few questions about the code.
1. In your PI_DeepONet_pendulum.ipynb,the input of branch net is u_train, the input of trunk net is y_train, and t…
